Science 701 Chapter 6 Lesson 5 Noninfectious Disease Review
allergen
any substance that causes an allergy
Type II
this form of diabetes usually develops in adulthood. either body cells stop responding normally to insulin or the pancreas stops making enough insulin. some of these people can control their symptoms through diet, weight control, and exercise.
stress, heavy exercise, tobacco smoke, air pollution, strong odors, and respiratory infections
list some factors that can trigger an asthma attack
histamine
this is a chemical that is responsible for the symptoms of an allergy, such as a rash, sneezing, and watery eyes
asthma
this is a disease in which the airways in the lungs narrow significantly
allergy
this is a reaction caused when the immune systen is overly sensative to a foreign substance--something not normally found in the body
insulin
this is the substance that enables body cells to take glucose from the blood and use it for energy
false. not all
true or false: *all* tumor cells are cancerous
false. allergens
true or false: *asthma* signals cells in the body to release a substance called histamine
true
true or false: people with diabetes have high leels of insulin in their blood but not enough of it in their *body* cells
pollen, dust, molds, some foods, pet dander, and some medicines
what are some examples of an allergen?
surgery, radiation, and drugs
what are the 3 ways you can treat cancer?
the muscles around the airways tighten and the inner walls of the airways become irritated, red, swollen, and warm. they produce mucus, which clogs the airways
what happens during an asthma attack?
a disease in which cells multipy uncontrollably destroying healthy tissue
what is cancer?
pancreas
what organ in your body produces insulin?
to open the airways and to reduce swelling
why wouuld you need to use an inhaler during an asthma attack?
noninfectious disease
these are disease that are not caussd by pathogens
Type I
this form of diabetes often forms in childhood. the pancreas produces little or no insult. these people need insulin injections
antihistamines
______ are drugs that interfere with the action of histamine may lesson the reaction
tumors
as cells divide over and over, they often form abnormal masses of cells called this
carcinogens
factors in the environment called _______ can also cause cancer
avoiding tobacco and sunlight, low-fat diet with fruits and veggies, and regular check-ups
how can someone prevent getting cancer?
allergies cause an inflammatory response, asthma affects breathing, and diabetes affects how body cells take up glucose
how do allergies, asthma, and diabetes affect the body?
cells from a tumor break away and enter the blood or lymph vessels. the blood or lymph carries the cancer cells to other parts of the body
how do cancerous tumors invade and destroy the healthy tissue around them?
diabetes
in the condition called ______, either the pancreas produces too little insulin or body cells do not insulin properly
