Name: A type of white blood cells that “chew” up invading organisms. Phagocytes Are parts of the blood and have three main functions. White Blood Cells A set of proteins made in the liver that work with antibodies. Complement System Makes new blood cells both red and white. Is a lymph node that produces lymphocytes, and is behind your scapula. Thymus A type of white blood cells that allow the body to recognize and remember previous invaders and help destroy them. Lymphocytes Is a clearish/white liquid that surrounds cells with water, nutrients and oxygen. It collects wastes and gets proteins from cells. Lymph Is an organ that filters the blood for foreign cells and worn out red blood cells. Are glands that filter and trap bacteria and viruses. They are “bean-shaped.”’ Lymph Nodes Are produced by the white bold cells and are “Yshaped” proteins that attach to specific germs (bacteria, virus, and/or toxins). They signal other cells to destroy them. Antibodies The reaction of the body to a germ that has gotten passed the physical barriers and into the body. These white blood cells produce antibodies. They mature in bone marrow. B-cells Tonsils These white blood cells destroy virus-infected cells. They mature in the thymus. T-cells Immune Response A series of vessels that drain and filter lymph to find and remove bacteria. Bone marrow Spleen Are cells that engulf (surround) cells that have been infected by viruses. They transfer a piece of the virus to its surface to signal other cells. Macrophages Is when your body remembers how to fight a disease you have had before. Immunity Is a lymph node at the back of your throat. Lymph System Lymph moves through the body in hollow tubes of tissue. Lymph vessels Are chemicals produced by the body to control different functions and/or lymphocytes production. Hormones Is the organ that is the body’s primary defense against pathogens invading the body. Skin
