1. Blood is taken to the lungs to become oxygenated and returned to the heart before being pumped through the body. Which blood vessels carry blood away from the heart?(1 point)
Responses
capillaries
veins
arteries
elastic
2. Oxygen is taken into the body from the environment, and carbon dioxide is removed from the body and released into the environment. Which body system is responsible for exchanging gases with the environment? (1 point)
Responses
endocrine system
circulatory system
nervous system
respiratory system
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.

1. The blood vessels that carry blood away from the heart are arteries.
2. The body system responsible for exchanging gases with the environment is the respiratory system.
3. The response predicted to happen when the person's muscles use up most of the oxygen in the blood is that the pulse and breathing rate increase to provide more oxygen.
4. The effect of atherosclerosis on the circulatory system would be that it would reduce blood flow and prevent tissues from oxygenating.
5. If the lining of the small intestine is damaged, it would prevent the body from obtaining the vitamins and nutrients it needs in order to perform properly.
1. The blood vessels that carry blood away from the heart are called arteries. To answer this question, you can recall the basic anatomy of the circulatory system. The circulatory system consists of the heart, blood vessels, and blood. The heart pumps oxygen-rich blood to the body through a network of blood vessels. The vessels that carry blood away from the heart are arteries.
2. The body system responsible for exchanging gases with the environment is the respiratory system. To answer this question, you can identify the different systems of the body and their functions. The respiratory system is specifically designed to facilitate the exchange of gases, such as oxygen and carbon dioxide, between the body and the environment. It includes organs such as the lungs, bronchi, and diaphragm.
3. The response that would happen because the muscles use up most of the oxygen in the blood during sprinting is that the pulse and breathing rate would increase to provide more oxygen. To answer this question, you can draw upon your knowledge of the body's response to exercise. During intense physical activity, the demand for oxygen increases, and the body responds by increasing the heart rate and breathing rate to deliver more oxygen to the muscles.
4. The effect that atherosclerosis would have on the circulatory system is that it would reduce blood flow and prevent tissues from oxygenating. To answer this question, you can recall the definition of atherosclerosis and its impact on the arteries. Atherosclerosis involves the build-up of fatty deposits on the artery walls, which can obstruct blood flow and reduce the amount of oxygen-rich blood reaching the tissues. This can lead to various health issues.
5. If the lining of the small intestine is damaged and prevents it from performing its function, it would affect the body by preventing it from obtaining the vitamins and nutrients it needs in order to function properly. To answer this question, you can consider the role of the small intestine in the digestive system. The small intestine is responsible for absorbing nutrients from digested food. If its lining is damaged, the absorption process would be impaired, leading to a deficiency in essential vitamins and nutrients that the body needs for proper functioning.
