Question

Explain how respiratory gases move in and out of type 1 alveolar cells. Explain why the movement of gases is important to respiratory physiology

Answer 1

Answer:

1)

Gas Exchange Between Alveolar Spaces and Capillaries:-

The function of the respiratory system is to move two gases: oxygen and carbon dioxide. ... Three processes are essential for the transfer of oxygen from the outside air to the blood flowing through the lungs: ventilation, diffusion, and perfusion

2)

Ventilation is the process that moves air into and out of the alveoli, and perfusion affects the flow of blood in the capillaries. Both are important in gas exchange, as ventilation must be sufficient to create a high partial pressure of oxygen in the alveoli
