IMMUNOLOGY

Detailed explanation-1: -A type of blood cell that is made in the bone marrow and found in the blood and lymph tissue. White blood cells are part of the body’s immune system. They help the body fight infection and other diseases.

Detailed explanation-2: -Leukocytes move out of blood vessels to the location of tissue damage in a movement known as extravasation.

Detailed explanation-3: -White blood cells are a part of your immune system that protects your body from infection. These cells circulate through your bloodstream and tissues to respond to injury or illness by attacking any unknown organisms that enter your body.

Detailed explanation-4: -But where do these dead cells go? Cells on the surface of our bodies or in the lining of our gut are sloughed off and discarded. Those inside our bodies are scavenged by phagocytes-white blood cells that ingest other cells. The energy from the dead cells is partly recycled to make other white cells.
