How to See Components of Blood?

Use a microscope, because of these components can’t see with naked eyes.

Then you would see lots of cells floating here. Most of them are red color. They are Red Blood Cells.

Now add a little drop of dilute Acetic Acid.

Now you can see other blood cells. They are White Blood Cells.

Red blood cells also known as Red Blood Corpuscles or Erythrocytes.

Erythrocytes have bi-concave shape with a movement.

Red blood cells are bigger in size.

Red color of the red blood cells is coming from Hemoglobin.

Hemoglobin is made from a Haematin that consist of iron and protein.

OxyHemoglobin is formed by the oxygen and hemoglobin in red blood cells.

Red Blood Cells

This is larger than red blood cells, however the amount of white blood cells is low. This is also known as, Leukocytes.

White blood cells are colorless and have nucleus.

1 white blood cell in 600 red blood cells

1 ml blood = 4000-11000 white blood cells

White Blood Cells

•Defeats bacteria production of antibodies.

•Produces anti-clotting protein called Heparin. •Produces chemical to stimulate the tissue damage repair called Hisstmine.

Certain leukocytes display an amoeboid movement, they engulf bacteria and viruses that enter to your body. This process of killing bad stuffs is known as Phagocytosis.

Phagocytes

Phagocytosis

Phagocytes are cells that protect the body by harmful foreign particles, bacteria anddead or dying cells,

Platelets are very small and have no nuclei.

These cells have granules.

When you are wounded, blood will not come out of the wound continuously due to the blood clotting process and it is quickened by platelets.
