WebAlveoli in exchange of gases: The human airway is composed of the nose, throat, nasal cavity, pharynx, trachea, epiglottis, alveoli, bronchioles, bronchi, and lungs. A small sac called alveoli helps with gas exchange. Alveoli have thin walls and a close network of blood arteries to allow gas exchange between blood and air-filled alveoli.

WebAdaptation of alveoli: The alveoli present in the lungs have thin walls composed only of a single layer of cells in order to minimize the diffusion distance. Their walls are moist which helps the gases to diffuse better. They are richly supplied with blood capillaries to ensure the efficient exchange of gases with the bloodstream. Webad 1 - Deoxygenated blood is brought to the alveoli. ad 2 - Diaphragm and intercostal muscles cause the volume of the lungs to increase and decrease in volume by CONTRACTIONS. This causes ventilation to occur. This in turn ensures a supply of high oxygen and low carbon dioxide AIR to the alveoli. Click the card to flip 👆.
