Body system gas exchange
WebJul 13, 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. WebThe majority of animals and plants are comprised of different types of cells and organised as tissues, organs and systems. The respiratory system in humans is a body system, finely adapted for efficient gas exchange. Organisms have to take in food, oxygen and water, and other essential substances, from the environment in order to grow and survive.
