What are the 4 components of the human blood?

Answer 1

There are four components of blood; red cells, white cells, platelets, and plasma. A little bit about each of them...

Red Blood CellsRed blood cells are the most prevalent of the four compounds in blood. Their main purpose is to get oxygen to all parts of the body. Blood is pumped through the heart, blood is oxygenated, then the red blood cells take this oxygen to parts of the body that need it, like the lungs. White Blood CellsWhite blood cells are the body's immune defenders. Once they detect a pathogen inside of the body, they spring into action and fight back. White blood cells literally consume the pathogens, completely engulfing them and erasing them from existence. The body has much less white cells than red cells, but the white cells are unequivocally vital. Platelets

The platelets help with homeostasis, which is the body's way of adapting to new external temperatures while keeping the inside within healthy levels, but they're also essential for blood clotting. When you get a cut, even a small one, maybe a paper cut, for instance! Anyway, the platelets clot the blood and stop the bleeding. Without them, the cut would just keep bleeding and bleeding. Now, that would just be a minor cut. If it was a larger injury, the danger would be even more sever. Extremely large injuries require medical attention though, as often the area is too large for the platelets to clot before significant blood loss occurs.

PlasmaPlasma is the body's main transport service. As I said above, the red cells do have a hand in transporting oxygenated cells, however, the body needs more than just oxygen, and that's when the plasma comes in. The plasma takes things the body needs, such as vitamins, minerals, cholesterol, etc. And transports it to the different parts of the body.

As you can see, each of the four things that make up the blood serve an essential role, and if any one of them was removed, you wouldn't be able to survive!
