Illnesses of the Immune System
Illnesses of the Immune System
Allergies- when the immune system reacts to harmless antigens
(____________________) such as pet dander, pollen, or dust. This triggers
the inflammatory response, causing sneezing, watery, itchy eyes, etc.
__________________________ can counteract these symptoms. Allergic
reactions in the respiratory system can create _____________________.

Autoimmune diseases- when the immune system attacks the body’s own
cells. Examples include _______________________________, in which
insulin-producing cells of the pancreas are attacked, causing increased or
erratic blood sugar levels, and also __________________, in which the
immune system makes antibodies that attack a person’s own proteins.

HIV and AIDS- HIV is a virus that attacks key cells within the immune system
(_____________________________________), leaving the body with
inadequate protection against pathogens. When an HIV-infected person’s T
cell count reaches about 1/6th the normal level, he or she is diagnosed with

(AIDS).

Leukemia- a group of cancers that affect the _________________________
and the blood cells made in the bone marrow. Remember, cancer Is caused
by mutations in genes that control the cell cycle, leading to unchecked cell
division. Chronic leukemia causes a high number of

resulting in an inadequate ability to fight pathogens. Leukemia can also
affect blood platelets and red blood cells, which can cause excessive
bleeding and anemia.
