MICROANATOMY

Detailed explanation-1: -Red blood cells also remove carbon dioxide from your body, bringing it to the lungs for you to exhale. Red blood cells are made in the bone marrow. They typically live for about 120 days, and then they die.

Detailed explanation-2: -The main role of red blood cells is to carry oxygen around your body and to transport carbon dioxide to the lungs, from where it can be exhaled.

Detailed explanation-3: -There are three means by which carbon dioxide is transported in the bloodstream from peripheral tissues and back to the lungs: (1) dissolved gas, (2) bicarbonate, and (3) carbaminohemoglobin bound to hemoglobin (and other proteins).

Detailed explanation-4: -In the human body, carbon dioxide is formed intracellularly as a byproduct of metabolism. CO2 is transported in the bloodstream to the lungs where it is ultimately removed from the body through exhalation.

Detailed explanation-5: -Red blood cells carry oxygen from our lungs to the rest of our bodies. Then they make the return trip, taking carbon dioxide back to our lungs to be exhaled.
