WebJun 8, 2024 · The purpose of the respiratory system is to perform gas exchange. Pulmonary ventilation provides air to the alveoli for this gas exchange process. At the respiratory membrane, where the alveolar and capillary walls meet, gases move across the membranes, with oxygen entering the bloodstream and carbon dioxide exiting. WebJan 24, 2024 · The gaseous exchange takes place between alveoli present in the lungs and the blood capillaries which are present around them. This is a process in which passive diffusion occurs. Oxygen is moved from the alveoli into the blood, and carbon dioxide is moved from the blood capillaries into the alveoli which is exhaled out of the body.
