1. arteries
2. respiratory system
3. The pulse and breathing rate increases to provide more oxygen.
4. This would reduce blood flow and prevent tissues from oxygenating.
5. This would prevent the body from obtaining the vitamins and nutrients it needs in order to perform properly.

3. A person sprints across a football field to make the touchdown. The person’s muscles use up most of the oxygen in the blood to accomplish this. Which response do you predict would happen because of this?(1 point)
Responses
The heart rate decreases to give more time for oxygen to enter.
The pulse and breathing rate increases to provide more oxygen.
The blood pressure drops because of a drop in blood volume.
The muscles begin to use carbon dioxide to power contractions.
4. Atherosclerosis is a disease that involves the accumulation of fatty deposits on the inner walls of the arteries that causes them to harden over time. This prevents the arteries from expanding and contracting. Which statement best describes the effect would this have on the circulatory system? (1 point)
Responses
This would prevent body tissues from getting much oxygen.
This would reduce blood flow and prevent tissues from oxygenating.
This would reduce the amount of blood flowing through the arteries.
There would be no effect on the flow of blood through arteries.
5. A person has a disease that damages the lining of the small intestine, preventing this organ from performing its function. How would this affect the body?
(1 point)
Responses
This would prevent the body from getting the amount of oxygen it needs to function properly.
This would prevent the body from obtaining the vitamins and nutrients it needs in order to perform properly.
This would have no effect on the body because the stomach and large intestine would compensate.
This would prevent the body from feeling any pain because no signals would make it to the brain.
