ANATOMY

Detailed explanation-1: -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.

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: -White blood cells do not transport carbon dioxide. White blood cells are part of the immune system and are responsible for identifying and removing pathogens from the body. Red blood cells are responsible for transporting oxygen and very small amounts of carbon dioxide.

Detailed explanation-4: -The majority of carbon dioxide is transported as part of the bicarbonate system. Carbon dioxide diffuses into red blood cells. Inside, carbonic anhydrase converts carbon dioxide into carbonic acid (H2CO3) ( H 2 CO 3 ), which is subsequently hydrolyzed into bicarbonate (HCO−3) and H+.

Detailed explanation-5: -Red blood cells contain a protein called hemoglobin, which carries oxygen from the lungs to all parts of the body. Checking the number of red blood cells in the blood is usually part of a complete blood cell (CBC) test. It may be used to look for conditions such as anemia, dehydration, malnutrition, and leukemia.
