45% cells, mostly red blood cells(Erythrocytes),other cells: white blood cells(leucocytes) and platelets(tiny fragments of cells)
What blood protein carrys fat around the body?
Lipoproteins
What are the two main forms of lipoprotein?
•High density lipoprotein (HDL) (good)
Prevents and reverses harmful deposits made by LDL.
•Low density lipoprotein (LDL) (bad)

What are some of the main areas in the body that the blood transports elements?
From the digestive system to the tissues or to storage areas such as the liver.
How is oxyhaemoglobin made?
The iron in red blood cells called haemoglobin combines with oxygen to create the dark red substance. Oxygen is released and darker hemoglobin is formed.
How is hemoglobin transported?
(Components of blood)
Erythrocytes have no cell nucleus so it’s able to carry the maximum amount of hemoglobin. As well as this they have a special disk shape to transfer the oxygen within. It will be transported around the bay providing oxygen to everything and on the trip back to the lungs carry a small amount of carbon dioxide.
What are some examples of hormones that blood transport? And how?
Insulin and adrenalin are produced in glands. They travel in blood to target organs m, to trigger response, process and growth. For example fertility or puberty.
