Blood carries oxygen round the body; arteries are the vessels that take it from the heart after it has been oxygenated by the lungs, while veins carry it back to the heart when it has been depleted of oxygen.
Blood is the bright red fluid that is pumped from the heart and is circulating in human body through arteries, veins and capillaries. It is not a mere liquid, for there are several minute bodies floating in it. These area known as corpuscles. Some of them are red and some white. Red corpuscles form nearly one half of the volume of blood. There for the color of the blood is red. White corpuscles are very little in blood, only 7,500 in one cubic millimeter of blood. But this small quantity of white cells is vitally important for the human body. They perform a very important function because they have the power to eat up invading becteria and thus protect the body from disease. Several functions of blood are :
(a) Blood absorbs the food-constituents from the food canal and distributes them to the tissues. The changes undergone by the food in different workshops enable the food constituents to mix with the blood .
(b) Blood absorbs the oxygen contained in the air, which is. Breathed in and takes it all over the body of oxidation. Red corpuscles of the blood carry out this function of carryingthe oxygen.
(c) Blood carries away the waste materials that are formed in the tissues to the kidneys, lungs and the skin from where they are thrown out.
(d) Besides the functions given above, blood serves another important purpose, that of defence. The white corpuscles constitute the arm y of the human body. When bacteria enters the body, it attacks the tissues and causes disease. The white corpuscles fight the bacteria, destroys it and get rid of it.

Two main functions include protection and support. A third function that can be considered is that it provides a place for muscles to attach to.
To synthesize proteins that are fed into the lumen of the rough ER by ribosomes that stud the rough ER surface and ship these proteins to the Golgi apparatus for further modification

Blood contains red blood cells. Red blood cells don't contain blood. Blood does not enter the red blood cell.
Blood cells are a part of blood. Blood is not a part of blood cells. Blood can't flow backward and forward within blood cells. Blood cells can flow backward and forward within blood.
55% of the whole blood is blood plasma.
Common blood can be transfered to rare blood but rare blood can not be transfered to common blood.
blood is made out of blood
