Blood is a highly specialised tissue , composed of many different kinds of components, red cells, white cells, platelets and plasma.
The blood plasma in needed because without it nothing would flow. Plasma is the liquid part of the blood and is about 90% water in which the RBC, WBC and platelets are suspended. The rest of it consists of dissolved food and waste substances, mineral ions. The major protein in plasma is Albumin. Albumin helps keep the blood from flowing out of the blood vessels and into tissues. Albumin binds to and carries substances like hormones. Albumin is made in the liver serum it helps it transport round the body together. The serum Albumin helps maintain the osmotic pressure of the blood.
Red blood cells specialist name is erthocytes and the white blood cells specialist name is leukocytes.
RBC transport oxygen from the lungs to the where it is needed and carry away carbon dioxide.
WBC identify and bind to bacteria, viruses and fungi so they can be removed. WBC are larger than red cells and there aren't as many white cells as red.
Platelets are produced by cells which break up into small fragments, these fragments do not contain a nucleus but are capable of producing enzymes involved in blood clotting.
Plasma carries RBC, WBC, platelets around, they contain sugar fat and protein. 55% of blood volume is made up of plasma. Plasma allows blood to navigate fast moving substances in solution, and slow moving thicker substances in suspension. Solution(dissolves) suspension (sits on the water).
As the heart pumps blood to the cells the plasma brings nourishment to them and removes any waste products.
