How do red blood cells do their job?

Answer 1

A red blood cell's main function is carrying oxygen in the blood to various cells in the body, it uses a protein called haemoglobin for that purpose, where it picks up oxygen in the lungs, or gills in case of fish and releases it in the tissues via the blood.

Red blood cells also remove carbon dioxide from the body

Answer 2

The primary function of red blood cells is to carry oxygen from the lungs to every cell in the body. Red blood cells are composed mostly of hemoglobin and lack many of the components found in most cells, including a nucleus. Hemoglobin captures oxygen molecules as the blood moves through the lungs. The oxygen is released to cells as the heart pumps the blood throughout the body.

Answer 3

The function of red blood cells is to transport oxygen. To do this they need a chemical that will loosely combine with oxygen, so that it will carry oxygen along with it but will also release it when needed. This chemical is called hemoglobin. That is a large, complicated protein which contains one iron atom. Becasue the iron is bonded to the protein, it does not form as strong a bond to oxygen as it would in the case of pure iron that was rusting. The degree of bonding is very precise.

Answer 4

Red blood cells transport oxygen from the lungs to the body's tissues and carry carbon dioxide back to the lungs for excretion. They achieve this through the protein hemoglobin, which binds to oxygen in the lungs and releases it in tissues. Red blood cells lack a nucleus, maximizing their capacity to carry oxygen.

Answer 5

It helps transports oxygen through-out the body.

Answer 6

they bring oxygen from the lungs to bring the oxygen to the organs,muscles,etc, that need the oxygen.

Answer 7

blood cells work in ether if there red they are ment to send oxeygen around there bodey and white are made to fight of infections and viruses

Answer 8

it goes through your blood
