What does blood do as it travels around your body?

Answer 1

Red blood cells aid in necessary functions of the body, such as carrying oxygen through your blood to muscles and organs. Pretty much everything in your body. Without red blood cells or low red blood cells you are either dying, anemic, or could have sickle cell anemia. Red blood cells also help remove CO2 and other waste gases from your body.

Answer 2

There are mutivolume books written on this, but in short:

red blood cells carry oxygen from the lungs to the rest of the body and Carbon Dioxide from the body back to the lungs to be exhaled

White blood cells aid in fighting infections and disease among other functions

Platelets allow the blood to clot

Plasma carries nutrients to body cells and transports wastes away to be disposed of

The blood also transports hormones throughout the body

A very incomplete answer, but that should get you started

Answer 3

Blood flows around all the vessels, and due to diffusion and osmosis, water, vitamins and gasses are exchanged between cells and blood. Oxygen is delivered and CO2 is taken away. Also, depending on circumstances, it can rise to the surface of the skin to cool the body down.

Answer 4

Answer 5

It transfers Oxygen and nutrients to each individual body cell.

Answer 6

Your body uses blood to transport oxygen from one body part to another. It also uses blood to transfer many other things like cells and whatnot. The blood is important.
