Does blood bring oxygen to the cells and carries carbon dioxide away?

Answer 1

Yes. It takes oxygen everywhere. Your feet, hands, arms, elbows, legs, head, stomach, etc.

Arteries branch almost endlessly down into capillaries [capillary tubules - lined by a single epithelial-Cell layer thick capillary membrane] and then immediately de-branch into the collecting veins.

Answer 2

CO2 is a small molecule. In most cases, it diffuses out of the cell into surrounding interstitial fluid which is then reabsorbed into the lymphatic vessels and dumped into the blood to be taken to the lungs where the CO2 is exchanged for O2.

Answer 3

The red blood cells collect carbon dioxide from the cells in the body and carry it back to the lungs. Carbon dioxide binds to the heme moiety on the hemoglobin molecule in a way that's similar to how oxygen does.

Depending on how you look at it, you might say the blood plasma carries some carbon dioxide also, in the form of a carbonate buffer. This helps your body maintain the proper blood pH.

Answer 4

Yes, red blood cells transport oxygen from the lungs to the cells and tissues, and they also carry carbon dioxide away from the cells back to the lungs to be exhaled. This process is essential for the body to function properly and maintain cellular respiration.

Answer 5

Red blood cells, after they "drop off" the oxygen. This exchange happens in the capillaries.

Answer 6

no the blood is only flowing on our body

Answer 7

yes

Answer 8

Yes!
