6. Why is pulmonary ventilation essential in the respiratory process?
Pulmonary ventilation, which is the process of moving air in and out of the lungs, is essential for maintaining proper gas exchange. It ensures a continuous supply of fresh oxygen to the alveoli for diffusion into the blood and the efficient removal of carbon dioxide from the blood to be exhaled. Without adequate ventilation, gas exchange would be impaired, leading to hypoxia or hypercapnia.
