Red blood cells transport ____ around our body.
A
oxygen and carbon dioxide
B
plasma
C
oxygen
D
carbon dioxide
Explanation: 

Detailed explanation-1: -What do red blood cells do? Red blood cells are responsible for transporting oxygen from your lungs to your body’s tissues. Your tissues produce energy with the oxygen and release a waste, identified as carbon dioxide. Your red blood cells take the carbon dioxide waste to your lungs for you to exhale.

Detailed explanation-2: -Red blood cells squeeze through narrow capillaries in single file. Haemoglobin molecules inside red blood cells pick up and carry the oxygen. These oxygen-rich cells travel in the blood vessels from the lungs to the left side of the heart. The blood is then pumped around the body.

Detailed explanation-3: -A protein called haemoglobin in the red blood cells then carries the oxygen around your body. At the same time, carbon dioxide that is dissolved in the blood comes out of the capillaries back into the air sacs, ready to be breathed out.

Detailed explanation-4: -Carbon dioxide can be transported through the blood via three methods. It is dissolved directly in the blood, bound to plasma proteins or hemoglobin, or converted into bicarbonate. The majority of carbon dioxide is transported as part of the bicarbonate system.

Detailed explanation-5: -What Is the Function of Red Blood Cells? 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.
