Question

Describe the various types of blood cells.Also discuss their functions​

Answer 1

The cellular portion of blood contains red blood cells (RBCs), white blood cells (WBCs) and platelets. The RBCs carry oxygen from the lungs. The WBCs help to fight infection, and platelets are parts of cells that the body uses for clotting. All blood cells are produced in the bone marrow.

Answer 2

Answer:

There are three types of blood cells. They are:

• Red blood cells (Erythrocytes)
• White blood cells (Leukocytes)
• Platelets (Thrombocytes)

Functions:

Red blood cells (Erythrocytes)

1. Transport oxygen from the lungs to the cells of the body.
2. Pick up carbon dioxide from other tissues and unload it in the lungs.

White blood cells (Leukocytes)

1. Kills bacteria through the process of phagocytosis.
2. They also release a burst of super oxides that have the ability to kill many bacteria at the same time.

Platelets (Thrombocytes)

• Platelets are the parts of cells that the body uses for clotting.
• Helps to promote other blood clotting mechanisms. Example: Secrete pro coagulant as (clotting factors) to promote blood clotting.
• They secrete vasoconstrictors which constrict blood vessels, causing vascular spasms in broken blood vessels.
• They secrete chemicals that attracted neutrophils and monocytes to sites of inflammation.
• Dissolve blood clots when they are no longer needed.
• Digest and destroy bacteria.
• They secrete growth factors to maintain the linings of blood vessels.
