The Immune System A lymphosyte is invited to a monosYte's house. "Would you like some coffee?"- asks the monoSyte. The lymphosyte replies "i'm more of a tea cell"

The immune system protects your body from pathogens. Pathogens are germs that cause disease. When white blood cells attack pathogens, the pathogens are filtered into the lymph. Lymph is a clear liquid that surrounds body cells and circulates in lymph vessels. Lymph carries harmful pathogens and other particles to lymph nodes. Lymph nodes are structures that filters and destroys pathogens. The spleen is an organ on the left side of the abdomen that filters foreign matter from the blood and lymph.
Immunity is the body's resistance to disease-causing agents. White blood cells are formed in bone marrow and circulates in the blood. These white blood cells are changed into T cells within the thymus gland. A T cell is a white blood cell that destroys pathogens. A B cell is another kind of specialized white blood cell that produces antibodies. An antibody is a special protein that helps fight infection.
How to Keep Your Immune System Healthy: 1. Choose foods that are high in protein and vitamin B.
2. Keep accurate records of all immunizations.
3. Get plenty of rest and sleep.
4. Exercise to keep bones dense and to protect bone marrow.
