GROSS ANATOMY

Detailed explanation-1: -White blood cells, also called leukocytes (LOO-kuh-sytes), play an important role in the immune system. Some types of white blood cells, called phagocytes (FAH-guh-sytes), chew up invading organisms. Others, called lymphocytes (LIM-fuh-sytes), help the body remember the invaders and destroy them.

Detailed explanation-2: -The acquired immune system, with help from the innate system, makes special proteins (called antibodies) to protect your body from a specific invader. These antibodies are developed by cells called B lymphocytes after the body has been exposed to the invader. The antibodies stay in your child’s body.

Detailed explanation-3: -Antibodies are protective proteins produced by your immune system. They attach to antigens (foreign substances)-such as bacteria, fungi, viruses and toxins-and remove them from your body.

Detailed explanation-4: -Granulocytes are a key component of the innate immune system (ie, nonspecific immune defense system). The granulocyte network includes 3 main components: neutrophils, eosinophils, and basophils. This network makes up 50% of the body’s circulating WBCs.
