Lesson 3.1 Class Questions
1. People who do little or no physical activity that tend to suffer more health
problems than active people. These health problems are known as
hypokinetic conditions. What are some examples of hypokinetic
conditions?
Cardiovascular disease, cancer, diabetes, obesity, osteoporosis
2. What does the cardiovascular system do?
Heart pumps blood into the arteries, arteries carry blood with oxygen to
the muscles and other body tissues, veins carry blood back to the heart;
heart pumps blood to the pulmonary artery and lungs provide oxygen to
the body.
3. What are the risk factors for cardiovascular disease?
Sedentary living ( not active), high fat diet, smoking, and high blood
pressure.
4. Two kinds of cardiovascular disease are coronary artery disease and
stroke. In each case, what happens to the arteries and what is this
process called and how is this related to blood pressure?
Coronary artery disease is the clogging of the arteries; stroke is a
condition that occurs when a blood vessel in brain is blocked or ruptured
so that oxygen is not supplied to the brain tissues; high blood pressure
occurs when the pressure in the arteries become too high or when the
arteries are clogged.
5. After having your blood pressure taken, you are given two numbers.
What do these numbers represent?
The higher number is the systolic pressure and it represents the pressure
in the arteries right after the heart beats; the lower number is the
diastolic pressure and it represents the pressure in the arteries before the
heart bears.
6. Describe what diabetes is. There are two types. Do you know the
difference? Why is Type II diabetes referred to as a hypokinetic
condition?
Diabetes is too much sugar in the blood; having too little insulin to help
control blood sugar is Type I and not being able to use insulin to control
blood sugar is Type II.
