Answer 1

Explanation:

Blood, fluid that transports oxygen and nutrients to the cells and carries away carbon dioxide and other waste products. Technically, blood is a transport liquid pumped by the heart (or an equivalent structure) to all parts of the body, after which it is returned to the heart to repeat the process.

Blood cells are divided into three main types: Red cells (erythrocytes). These make blood a red colour. One drop of blood contains about five million red cells. A constant new supply of red blood cells is needed to replace old cells that break down.

Answer 2

Your blood is made up of liquid and solids. The liquid part, called plasma, is made of water, salts, and protein. Over half of your blood is plasma. The solid part of your blood contains red blood cells, white blood cells, and platelets. Red blood cells (RBC) deliver oxygen from your lungs to your tissues and organs.

One drop of blood contains about five million red cells. A constant new supply of red blood cells is needed to replace old cells that break down.

Blood is made mostly of plasma, but 3 main types of blood cells circulate with the plasma:

Platelets help the blood to clot. Clotting stops the blood from flowing out of the body when a vein or artery is broken. ...

Red blood cells carry oxygen. ...

White blood cells ward off infection.
