They migrate towards tissues where they are needed and become functional performing various activities. WBCs can be divided into 2 groups: Polymorphonuclear granulocytes and mononuclear agranulocytes. Both types are spherical while suspended in blood plasma but when they invade tissues after leaving the blood vessels they become amoeboid...

The Lymphatic System

contains white blood cells (lymphocytes) and drain it back into the blood. This helps get rid of; toxins, waste and any foreign bodies within a human. The lymphocytes are cells of the immune system which helps the body to fight diseases. There are two types of lymphocytes; T and B lymphocytes. Unlike our blood, which travels through the body in a continuous loop, lymph only travels in one direction which is up towards the neck, within its own system. The tissue fluid flows into our venous blood stream...

The Inflammatory Response

the body’s cells. These toxins trigger the initiation of the inflammatory response. The changes that occur are initiated by the interactions between bacterial products and inflammatory mediators. Inflammatory mediators are chemicals that are released by protective cells or plasma when harmful agents invade the body. Inflammatory mediators include histamine, prostaglandins, and leukotrienes (Kumar, Abbas, Fausto, Robbins, & Cotran, 2005). The main cells involved are the mast cells and are located...

Informative Speech

are children. (St. Judes, 2013) • Leukemia is cancer of the blood and develops in the bone marrow. The bone marrow is the soft, spongy center of certain bones that produces the three major blood cells: white blood cells to fight infection; red blood cells that carry oxygen; and platelets that help with blood clotting and stop bleeding. When a child has leukemia, the bone marrow, for an unknown reason, begins to make white blood cells that do not mature correctly, but continue to reproduce themselves...

Staying Healthy

protects the body from physical damage, microbe infection and dehydration. Its dry, dead outer cells are difficult for microbes to penetrate, and the sebaceous glands produce oils that help kill microbes. Blood clotting If microorganisms get into the body through a cut in the skin, the most important thing to do is close the wound quickly so that no more microorganisms can enter. A scab does just that. The blood contains tiny structures called platelets, and a protein called fibrin. A scab is basically...
