Question

Name the following:

WBCs squeeze through the walls of capillaries into the tissue.

Answer 1

WBC

1. Leukocytes (also called white blood cells) are a cellular component of the blood that lacks haemoglobin, has a nucleus and is capable of motility.
2. They defend the body against infection and disease by ingesting foreign materials and cellular debris and by destroying infectious agents.
3. Granulocytes and agranulocytes are the two types of white blood cells or leukocytes.
4. Granulocytes contain granules in their cytoplasm and agranulocytes do not.
5. The three types of granulocytes are neutrophils, eosinophils, and basophils.
6. The two types of agranulocytes are lymphocytes and monocytes.

Diapedesis

1. It is the movement of leukocytes out of the circulatory system and towards the site of tissue damage or infection.
2. Most WBCs are amoeboid and can produce pseudopodia with which they can squeeze through the walls of capillaries into the tissues to fight the disease causing agents.
