Worksheet #2: IMMUNE SYSTEM
Find the term and write something about it.
Adenoid- are lymph tissues that sit in your upper airway between your nose and the back of your throat.
Antibody- is a protein produced by the body's immune system when it detects harmful substances, called
antigens.
Axillary- The axillary region is the area between the superior portion of the upper limb and the thorax.
Cell- The smallest unit that can live on its own and that makes up all living organisms and the tissues of the
body.
Dendritic- dendritic cells are immune cells that effectively link the innate and adaptive arms of the immune
system.
Fluid- having particles that easily move and change their relative position without a separation of the mass and
that easily yield to pressure
Immunity- the immune system's way of protecting the body against an infectious disease.
Immunoglobulin- Also called antibodies. Antibodies are proteins that your immune system makes to fight
germs, such as viruses and bacteria.
Immunotherapy- a type of cancer treatment that helps your immune system fight cancer.

cancer.
Interleukin- One of a group of related proteins made by leukocytes and other cells in the body.
Lymph- Lymph is the fluid that flows through the lymphatic system, a system composed of lymph vessels and
intervening lymph nodes whose function, like the venous system, is to return fluid from the tissues to be
recirculated.
Macrophage- A type of white blood cell that surrounds and kills microorganisms, removes dead cells, and
stimulates the action of other immune system cells.
Monoclonal- Monoclonal antibodies are man-made proteins that act like human antibodies in the immune
system.
Natural- Natural immunity happens after a person gets sick with a disease. The body may recover after several
days of rest, but re-infections can happen, and may still result to death.
Node- small bean-shaped structure that is part of the body's immune system.
Paste- a thick, soft, moist substance typically produced by mixing dry ingredients with a liquid.
Plasma- the liquid portion of blood and about 55% of our blood is plasma.
Reading- The act of viewing and interpreting letters, words, sentences, and others.
Spleen- A small organ inside your left rib cage, just above the stomach. It's part of the lymphatic system.
Suppressor- A type of immune cell that blocks the actions of some other types of lymphocytes, to keep the
immune system from becoming over-active.
System- In medical meaning, a group of related organs that act together to perform a common function.
Thoracic- The thorax is also called the chest and contains the main organs of respiration and circulation.
Tolerance- In medical term, it is a condition that occurs when the body gets used to a medicine so that either
more medicine is needed or different medicine is needed.
Tonsil- a pair of soft tissue masses in the rear of the throat that trap germs that are breathed in.
Toxin- Substance created by plants and animals that are poisonous to humans. Toxin may also include some
medicines that are helpful in small doses, but poisonous in large amounts.
Vaccination- the administration of a vaccine to help the immune system develop immunity from a disease.
