-Oxygen Supply: Breathing allows the body to take in oxygen from the air. Oxygen is essential for the process of cellular respiration, where it combines with glucose to produce energy (ATP) that powers various bodily functions.
-Removal of Carbon Dioxide: As the body uses oxygen for energy, it produces carbon dioxide (CO2) as a waste product. Breathing helps eliminate excess CO2 from the body, preventing it from building up and becoming toxic.
-Maintaining pH Balance: The removal of CO2 through breathing also helps regulate the body's pH balance, ensuring that the blood remains at a slightly alkaline level, which is crucial for normal bodily functions.
-Respiration: Breathing facilitates the exchange of gases in the lungs, where oxygen is absorbed into the bloodstream, and CO2 is removed from the bloodstream and expelled through exhalation. This process is necessary to supply oxygen to the body's cells and remove waste gases.
-Brain Function: Oxygen is particularly essential for the brain. Without a continuous supply of oxygen, brain cells can quickly become damaged, leading to impaired cognitive function or even cell death.
