They are tiny air sacks sometimes described as being cauliflower-shaped. Oxygen diffuses across the lining of the alveoli and blood capillaries into and into red blood cells. Carbon dioxide diffuses from the blood to the alveoli. A concentration gradient is maintained by breathing as well as blood flow. The main adaptation of the gas exchange surface are: 1. Large surface area 2. Thin wall 3. Moist lining 4. Good blood supply 5. Good ventilation

Lung Anatomy and Physiology | Gas Exchange in the Lungs Respiration Transport Alveoli Nursing
 
08:01
Lung anatomy and physiology of gas exchange in the lung alveoli during respiration nursing lecture. This lecture details the anatomy of the lungs and how gas exchange in the lungs takes place between carbon dioxide and oxygen. The lung is made up of many components that participant in gas exchange. Inhaled air with oxygen enters into the upper respiratory system via the nose or mouth then through the nasal cavities, larynx, and trachea which splits at the carina into the right and left bronchus (primary bronchi). The primary bronchi and pulmonary vein and artery enter into the lungs at the hilum. The pulmonary artery delivers unoxygenated blood to the lungs, and the pulmonary vein delivers oxygenated blood back to the heart. The primary bronchi branches off into the lobar bronchi (also called secondary bronchi) then into the segmental bronchi (also called tetiary bronchi), and then into even smaller areas such as the bronchioles. The bronchioles connect to the alveolar sacs via the alveolar ducts. Gas exchange occurs in the alveolar sac within the alveoli. The alveoli sacs contain capillaries that help with transporting carbon dioxide and oxygen in and out of the body. The pulmonary artery brings unoxygenated blood through the capillary and carbon dioxide transports across the thin capillary wall and is transported out of the body through exhalation. Then the inhaled oxygen transports across the capillary wall onto the red blood cells which is taken via the pulmonary vein back to the heart to replenish the body with fresh oxygenated blood. Other facts about lung anatomy: the right lung has three lobes while the left lung has two lobes. The lung is made up of two layers: visceral pleura (surrounds the lungs) and parietal pleura (attaches to the thoracic cavity). In between these layers, is a small space of fluid that allows the lungs to glide on each other during inhalation and exhalation.

Gas exchange in different animals | Biology for All | FuseSchool
 
02:54
Respiration is carried out by all living things. Animals need oxygen to carry out aerobic respiration and they need to get rid of the waste product called carbon dioxide. This is called gas exchange. Swapping one gas for another. Animals have evolved different mechanisms for carrying out gaseous exchange. The most important thing is to create a large surface area, the bigger the surface area the faster diffusion of the gases can occur. Secondly they all have a good blood supply. You want to get oxygen into the blood and carbon dioxide out as quickly as possible so the blood travels very close to the exchange surface to once again maximise diffusion.

What Happens When You Breathe? How The Lungs Work Animation - Respiratory System Gas Exchange  Video
 
03:05
Breathing In (Inhalation) When you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. This increases the space in your chest cavity, into which your lungs expand. The intercostal muscles between your ribs also help enlarge the chest cavity. They contract to pull your rib cage both upward and outward when you inhale. As your lungs expand, air is sucked in through your nose or mouth. The air travels down your windpipe and into your lungs. After passing through your bronchial tubes, the air finally reaches and enters the alveoli (air sacs). Through the very thin walls of the alveoli, oxygen from the air passes to the surrounding capillaries (blood vessels). A red blood cell protein called hemoglobin (HEE-muh-glow-bin) helps move oxygen from the air sacs to the blood. At the same time, carbon dioxide moves from the capillaries into the air sacs. The gas has traveled in the bloodstream from the right side of the heart through the pulmonary artery. Oxygen-rich blood from the lungs is carried through a network of capillaries to the pulmonary vein. This vein delivers the oxygen-rich blood to the left side of the heart. The left side of the heart pumps the blood to the rest of the body. There, the oxygen in the blood moves from blood vessels into surrounding tissues. Breathing Out (Exhalation) When you breathe out, or exhale, your diaphragm relaxes and moves upward into the chest cavity. The intercostal muscles between the ribs also relax to reduce the space in the chest cavity. As the space in the chest cavity gets smaller, air rich in carbon dioxide is forced out of your lungs and windpipe, and then out of your nose or mouth. Breathing out requires no effort from your body unless you have a lung disease or are doing physical activity. When you're physically active, your abdominal muscles contract and push your diaphragm against your lungs even more than usual. This rapidly pushes air out of your lungs. How the Lungs and Respiratory System Work You usually don't even notice it, but twelve to twenty times per minute, day after day, you breathe -- thanks to your body's respiratory system. Your lungs expand and contract, supplying life-sustaining oxygen to your body and removing from it, a waste product called carbon dioxide. The Act of Breathing Breathing starts at the nose and mouth. You inhale air into your nose or mouth, and it travels down the back of your throat and into your windpipe, or trachea. Your trachea then divides into air passages called bronchial tubes. For your lungs to perform their best, these airways need to be open during inhalation and exhalation and free from inflammation or swelling and excess or abnormal amounts of mucus. The Lungs As the bronchial tubes pass through the lungs, they divide into smaller air passages called bronchioles. The bronchioles end in tiny balloon-like air sacs called alveoli. Your body has over 300 million alveoli. The alveoli are surrounded by a mesh of tiny blood vessels called capillaries. Here, oxygen from the inhaled air passes through the alveoli walls and into the blood. After absorbing oxygen, the blood leaves the lungs and is carried to your heart. Your heart then pumps it through your body to provide oxygen to the cells of your tissues and organs. As the cells use the oxygen, carbon dioxide is produced and absorbed into the blood. Your blood then carries the carbon dioxide back to your lungs, where it is removed from the body when you exhale. The Diaphragm's Role in Breathing Inhalation and exhalation are the processes by which the body brings in oxygen and expels carbon dioxide. The breathing process is aided by a large dome-shaped muscle under the lungs called the diaphragm. When you breathe in, the diaphragm contracts downward, creating a vacuum that causes a rush of fresh air into the lungs. The opposite occurs with exhalation, where the diaphragm relaxes upwards, pushing on the lungs, allowing them to deflate. Clearing the Air The respiratory system has built-in methods to prevent harmful substances in the air from entering the lungs. Respiratory System Hairs in your nose help filter out large particles. Microscopic hairs, called cilia, are found along your air passages and move in a sweeping motion to keep the air passages clean. But if harmful substances, such as cigarette smoke, are inhaled, the cilia stop functioning properly, causing health problems like bronchitis. Mucus produced by cells in the trachea and bronchial tubes keeps air passages moist and aids in stopping dust, bacteria and viruses, allergy-causing substances, and other substances from entering the lungs. Impurities that do reach the deeper parts of the lungs can often be moved up via mucous and coughed out or swallowed. In the lungs, oxygen and carbon dioxide (a waste product of body processes) are exchanged in the tiny air sacs (alveoli) at the end of the bronchial tubes.

Travel of Air Through Respiratory System - Gas Exchange in the Lungs - Nose to Alveoli Pathway
 
02:10
Gas Exchange - Delivery of Oxygen & Elimination of Carbon dioxide - Medical Animation Air first enters the body through the mouth or nose, quickly moves to the pharynx (throat), passes through the larynx (voice box), enters the trachea, which branches into a left and right bronchus within the lungs and further divides into smaller and smaller branches called bronchioles. The smallest bronchioles end in tiny air sacs, called alveoli, which inflate during inhalation, and deflate during exhalation. Gas exchange is the delivery of oxygen from the lungs to the bloodstream, and the elimination of carbon dioxide from the bloodstream to the lungs. It occurs in the lungs between the alveoli and a network of tiny blood vessels called capillaries, which are located in the walls of the alveoli. The walls of the alveoli actually share a membrane with the capillaries in which oxygen and carbon dioxide move freely between the respiratory system and the bloodstream. Oxygen molecules attach to red blood cells, which travel back to the heart. At the same time, the carbon dioxide molecules in the alveoli are blown out of the body with the next exhalation.

Always seek the advice of a qualified healthcare provider with any questions you may have regarding a medical condition. pH is an indicator of acidity. The body’s blood pH is strictly regulated within a narrow range between 7.35 and 7.45. This is because even a minor change in acidity may have devastating effects on protein stability and biochemical processes. Normal cellular metabolism constantly produces and excretes carbon dioxide into the blood. Carbon dioxide combines with water to make carbonic acid which dissociates into hydrogen ions and bicarbonate. This equilibrium is central to understand acid-base regulation. CONTINUED carbon dioxide production by all cells of the body drives the equilibrium to the right to generate more hydrogen ions. Because pH is basically a function of hydrogen ion concentration, more hydrogen means higher acidity and lower pH. Normal metabolism, therefore, constantly makes the blood more acidic. The body must react to keep the blood pH within the normal limits. This is achieved by 2 mechanisms: - Elimination of carbon dioxide through exhalation. The amount of carbon dioxide exhaled by the lungs is regulated in response to changes in acidity. A decrease in pH is sensed by central or arterial chemoreceptors and leads to deeper, faster breathing; more carbon dioxide is exhaled, less hydrogen is made, blood acidity decreases and blood pH returns to normal. Pulmonary regulation is fast, usually effective within minutes to hours. - Excretion of hydrogen ions and reabsorption of bicarbonate through the kidneys. The kidneys control blood pH by adjusting the amount of excreted acids and reabsorbed bicarbonate. Renal regulation is slower; it usually takes days to respond to pH disturbances. Pathologic changes may cause acid-base disturbances. Acidosis refers to a process that causes increased acidity, while alkalosis refers to one that causes increased alkalinity. It’s not uncommon for a patient to have several processes going on at once, some of them in opposite directions. The resulting plasma pH may be normal; too acidic, called acidemia; or too basic, called alkalemia. Acidosis may result from inadequate function of the lungs which causes arterial carbon dioxide to accumulate. This is RESPIRATORY acidosis. On the other hand, METABOLIC acidosis may result from excessive production of metabolic acids, decreased ability of the kidneys to excrete acids, ingestion of acids, or loss of alkali. Metabolic acidosis is characterized by primary decrease in plasma bicarbonate.

ANATOMY OF THE LUNGS
 
05:22
The lungs are organs that allow you to breathe and are located in the thoracic cavity on either side of the heart and near the backbone. Their bases sit on the diaphragm, and their apexes extend into the root of the neck. The lungs perform gas exchange in microscopic alveoli, extracting oxygen from the air and transferring it to your bloodstream, while releasing carbon dioxide. The respiratory system can be functionally divided into a conducting zone and a respiratory zone. The conducting zone forms a continuous passage for air moving in and out of the lungs, and includes the nose, pharynx, larynx, bronchi, and bronchioles. The respiratory zone is found deep in the lungs and is involved in gas exchange. This includes the respiratory bronchioles, alveolar ducts, and alveoli, which are air sacs 100-300 µm wide that allow gas exchange. The respiratory system can also be divided anatomically into the upper and lower respiratory tracts. The upper respiratory tract consists of structures in the head and neck – in other words, the nose, pharynx, and larynx. The lower respiratory tract is located in the chest and includes the trachea, bronchi, bronchioles, alveolar ducts, and alveoli. The lungs weigh around 1.3 kg and contain around two and a half thousand km of airways. The right lung is larger and heavier than the left, because the left needs to leave room for the heart. The right lung is subdivided into three lobes, while the left has two. However, the left lung has a structure homologous to the middle lobe of the right lung. On the left lung, the upper lobe has a projection called the “lingula”. The boundaries of these lobes are defined by fissures. The right lung has two fissures, one oblique and one horizontal. The left lung has only an oblique fissure. The main, or primary, bronchi enter the lungs at the hilum, which is the area on the mediastinal surface of the lung through which structures enter and leave the lung. These primary bronchi branch into lobar, or secondary, bronchi, which supply air to each lobe of the lungs. The secondary bronchi then branch into segmental, or tertiary bronchi, which supply air to bronchopulmonary segments, which are subdivisions of the lobes. A bronchopulmonary segment has its own segmental bronchus and arterial supply. The bronchi branch into bronchioles. The primary lobule, otherwise called the acinus, is the functional unit of the lung. It is composed of a single terminal bronchiole, numerous respiratory bronchioles, alveolar ducts, alveolar sacs, and around 10,000 alveoli. Pulmonary blood is delivered to it by a pulmonary arteriole and taken away by a pulmonary venule. The alveoli are where gas exchange takes place. Their 0.5-2 µm thick membranes form the blood-air barrier. Together, the 300-500 million alveoli in the lungs provide a huge surface area for gas exchange. Elastic fibers allow the alveoli to expand on inhalation. These spring back on exhalation to help expel carbon dioxide. The lungs have a unique blood supply. They have two forms of circulation – pulmonary and bronchial. The pulmonary circulation brings deoxygenated blood from the body to the lungs via the pulmonary arteries and returns it via pulmonary veins. Meanwhile, the bronchial circulation provides oxygenated blood to the tissue of the lungs. The lungs have very specific indentations from surrounding structures. The outer surface of the lungs faces the ribs, which make light indentations on them. The medial surfaces are even more interesting. We can see impressions of the heart, and the great vessels, which are the large vessels that bring blood to and from the heart. The lungs can’t power the breathing process on their own, but only expand with the expansion of the thoracic cavity. Instead, muscles of respiration, primarily the diaphragm, drive breathing. The broad, concave base of the lungs sits on the convex surface of the diaphragm. The intercostal muscles pull the rib cage upwards. The respiratory muscles relax when you breath out. When you’ve breathed out, the volume of the air remaining in your lungs is called the functional residual capacity (FRC), which is around 2.5-3 L in an adult. When you’re exercising, heavy breathing recruits accessory muscles in the neck and abdomen, pulling the ribcage down upon exhalation and further decreasing the volume of the thoracic cavity to around 1 L. The movement of the lungs encounters little friction thanks to the pleural sac. This sac also divides the lungs into lobes. The pleurae are two serous membranes, one lining the inner wall of the ribcage, and one resting on the surface of the lungs. Between these membranes is the pleural cavity, which contains pleural fluid for lubrication. 3D MODELS: https://www.turbosquid.com/3d-models/3d-model-respiratory-anatomy-lung/602818 https://www.turbosquid.com/3d-models/human-torso-muscles-max/647193 https://www.turbosquid.com/3d-models/3ds-max-alveoli-anatomy/608346
