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
