Answer 1

Answer:

Hey

Explanation:

Your respiratory system's primary function is to breathe in air, absorb oxygen into the bloodstream and breathe out carbon dioxide. ... Air comes into the body through the nose or mouth, and enters the airways. Airways are the tubes that carry air into our lungs.

Answer 2

Explanation:

The process of physiological respiration includes two major parts: external respiration and internal respiration. External respiration, also known as breathing, involves both bringing air into the lungs (inhalation) and releasing air to the atmosphere (exhalation). During internal respiration, oxygen and carbon dioxide are exchanged between the cells and blood vessels.
