ANATOMY

Detailed explanation-1: -CO2 is toxic and must be eliminated; thus, CO2 exits the cells, enters the bloodstream, travels back to the lungs, and is expired out of the body during exhalation. The primary function of the respiratory system is to deliver oxygen to the cells of the body’s tissues and remove carbon dioxide.

Detailed explanation-2: -Warms air to match your body temperature and moisturizes it to the humidity level your body needs. Delivers oxygen to the cells in your body. Removes waste gases, including carbon dioxide, from the body when you exhale. Protects your airways from harmful substances and irritants.

Detailed explanation-3: -The nose, throat, and lungs are just a few parts of the body that make up the respiratory system. They work together to bring oxygen into the body and take carbon dioxide (a waste product) out.

Detailed explanation-4: -Gas exchange allows the body to replenish the oxygen and eliminate the carbon dioxide. Doing both is necessary for survival.

Detailed explanation-5: -Respiratory acidosis occurs when the lungs can’t remove enough of the carbon dioxide (CO2) that the body produces. Excess CO2 causes the pH of your blood and other bodily fluids to decrease, making them too acidic.
