The alveoli diagram
WebMar 28, 2024 · Respiratory zone: respiratory bronchioles, alveoli. Breathing cycle. Inspiration - diaphragm contracts and pulls down, intercostal muscles contract and expand the rib cage -> air enters the lungs. Expiration - diaphragm relaxes and goes up, intercostal muscles relax and rib cage collapses -> air exits the lungs. WebThe alveolar walls are moist - the layer of moisture allows the gases to dissolve more quickly. Alveoli have a good blood supply - due to close contact with capillaries making the gas exchange quicker and more efficient. Fig. 2 - Movement of gases between alveoli and capillaries.

WebThe alveoli are the final branchings of the respiratory tree and act as the primary gas exchange units of the lung. The gas-blood barrier between the alveolar space and the pulmonary capillaries is extremely thin, allowing for rapid gas exchange. To reach the blood, oxygen must diffuse through the alveolar epithelium, a thin interstitial space ... WebGas exchange occurs at two sites in the body: in the lungs, where oxygen is picked up and carbon dioxide is released at the respiratory membrane, and at the tissues, where oxygen is released and carbon dioxide is picked up. External respiration is the exchange of gases with the external environment, and occurs in the alveoli of the lungs.

WebMar 3, 2024 · Bronchiole Function. The function of the bronchioles is to deliver air to a diffuse network of around 300 million alveoli in the lungs. 5 As you inhale, oxygenated air is pulled into the bronchioles. Carbon dioxide collected by the alveoli is then released from the lungs as you exhale.
