WebGas Exchange Processes The exchange of oxygen and carbon dioxide occurs between the alveoli and the capillaries in the lungs Oxygen and carbon dioxide are exchanged in a process of simple diffusion; (passive movement from high to low concentration) The air in the alveoli contains a high concentration of oxygen.
WebAnimal respiratory systems are designed to facilitate gas exchange. In mammals, air is warmed and humidified in the nasal cavity. Air then travels down the pharynx, through the trachea, and into the lungs. In the lungs, air passes through the branching bronchi, reaching the respiratory bronchioles, which house the first site of gas exchange. mmtc gold rateWebJun 8, 2024 · Gas exchange in birds occurs between air capillaries and blood capillaries, rather than in alveoli.
