What is the purpose of the respiratory system?

The respiratory system’s primary function is to supply oxygen to the blood and remove carbon dioxide from the body. The process begins when air is inhaled into the lungs, where oxygen is transferred into the bloodstream through tiny air sacs called alveoli. The oxygenated blood is then transported to tissues throughout the body. The respiratory system also helps regulate the body’s pH by controlling the levels of carbon dioxide in the blood. Efficient respiration is vital for cellular metabolism and overall bodily functions.
