Question 3
SURVEY
30 seconds
Q. The rate at which blood flows through the human body changes in response to many factors. Which statement describes one of these factors and its effect on blood flow?
answer choices
A high viscosity of blood causes an increased resistance in the blood vessels and leads to slow blood flow.
A low blood pH decreases the rate of diffusion through the blood vessels and leads to slow blood flow.
The changing of the shape of red blood cells to a crescent shape decreases resistance and lead to a faster blood flow.
The narrowing of blood vessels increases pressure and leads to a faster blood flow.

Question 7
SURVEY
30 seconds
Q. Which of the following best describes the connection between cardiovascular disease and age?
answer choices
As people age, their blood vessels become more elastic leading to less cardiovascular disease.
As people age, the heart becomes more efficient with each pump, increasing cardiac output.
As people age, blood pressure decreases leading to more cardiovascular disease.
As people age, plaque builds up in the arteries increasing vessel resistance, which leads to disease.

Question 8
SURVEY
30 seconds
Q. A doctor examines a patient who has high blood pressure and atherosclerosis in the coronary artery. What medical condition connected to blood flow is most likely to affect this patient in the future?
answer choices
The patient may develop headaches and confusion due to cancer in the brain caused by years of low levels of oxygen supplied to the brain.
The patient may develop stiff joints and chest pains from the high blood pressure applied to the muscle and joint tissues of the body.
The patient may show signs of confusion, weakness, and partial paralysis due to high blood pressure when the plaque dislodges and blocks blood flow to the brain.
The patient may suffer a heart attack because of the reduction in blood flow to the heart muscles due to severe plaque build-up in the coronary artery
