What are the main functions of the respiratory system and what is the role of the diaphragm in breathing?
user
The network of tissues and organs that aids in breathing is known as the respiratory system. It comprises the blood vessels, lungs, and airways. The respiratory system also includes the muscles that move your lungs. Together these components circulate oxygen throughout the body and remove waste gases like carbon dioxide.
The respiratory system serves a variety of purposes. In addition to assisting with breathing, it also:
• It enables you to speak and smell.
•It also warms the temperature of the air to that of your body and moisturizes it to the humidity levels a body needs.
•Provides the body cells with oxygen
•Enables a body to exhale waste gases from the body
•Keeps irritants and harmful substances out of the airways.

The main muscle used for breathing is the diaphragm, which is situated below the lungs. It is a sizable, dome-shaped muscle that frequently contracts continually and rhythmically. The diaphragm's role in breathing is it contracts and tightens during inhalation and the chest cavity widens. This creates a vacuum through the contractions, drawing air into the lungs. The diaphragm relaxes and assumes its dome-like shape during exhalation, forcing air out of the lungs.
