Question

11. What is breathing? During the breathing cycle, what is the
advantage of the residual volume of air in the lungs? Explain
How is breathing different from respiration?​

Answer 1

Answer:

The residual volume functions to keep the alveoli open even after maximum expiration. In healthy lungs, the air that makes up the residual volume allows for continual gas exchange to occur between breaths. The oxygen-depleted residual air is then mixed with newly inhaled air to improve gas exchange at the alveoli.As stated above, breathing is the biological process of inhaling and exhaling of the gases between the cells and the environment. The mechanism of breathing involves various respiratory structures such as the windpipe, lungs, and nose. Respiration, on the other hand, is a chemical process that takes place in the

Answer 2

Answer:

Breathing is the process of moving air into and out of the lungs to facilitate gas exchange with the internal environment, mostly by bringing in oxygen and flushing out carbon dioxide.
