Arteries
- 3. Multiple Choice
Which of the following describes High Blood Viscosity?
There is a High Concentration of Blood cells and Solutes.
The Blood is Thicker
Blood Pressure Decreases
Heart rate and Pressure increase to move the Blood.
- 4. Multiple Choice
Which statement best describes Blood Pressure?
The Force applied on the Blood Vessels by the Heart
It’s Normal and Healthy to have extended periods of High Blood Pressure.
Your Blood Pressure is Higher when you Sleep.
Being Nervous can Decrease your Blood Pressure.
- 5. Multiple Choice
When an individual has Atherosclerosis, it forms Plaque within the Arteries.
How does Atherosclerosis affect Blood Flow?
Arterial plaque clogs the arteries, limiting or stopping blood flow.
Arterial plaque changes the direction of blood flow, which forces oxygenated blood to the heart.
Arterial plaque changes the size of blood cells, which prevents blood from flowing in the arteries.
Arterial plaque clears the arteries, increasing blood flow.
- 6. Multiple Choice
Flexibility in blood vessels allows the vessels to stretch and move based on changes in Blood Volume. Conditions like Hypertension can cause the arteries to harden and lose their Flexibility.
How would the hardening of the arteries most likely affect Blood Flow?
The hardening of the arteries would likely cause blood flow to remain constant.
The hardening of the arteries would likely increase blood flow.
The hardening of the arteries would likely cause blood flow to stop completely.
The hardening of the arteries would likely restrict blood flow.
- 7. Multiple Choice
Arteriosclerosis is a disease which clogs arteries in the human body. In arteriosclerosis, artery walls become thick. Fatty deposits build up on inner walls of arteries. This condition reduces the ability of arteries to perform their function. The diagram above shows a comparison between a healthy artery and one with arteriosclerosis. Which of the following explains how Atherosclerosis affects the Body?
Decreases the circulation of Blood to tissues
Assembles Amino Acids into Proteins
Replaces damaged Cells with new Cells
Breaks down Food particles into Molecules
- 8. Multiple Choice
Blood Volume and Blood Pressure are related.
What happens to Blood Pressure and the Heart Rate when there's an increase in Blood Volume?
Increase in Volume leads to a Decrease in HR and BP.
Increase in Volume leads to a Decrease in HR and an Increase in BP.
Increase in Volume leads to a Increase in HR and an Increase in BP.
Increase in Volume leads to a Increase in HR and BP.
- 9. Multiple Choice
A Doctor prescribes a Blood Thinner, like Aspirin, to a patient with a Heart Condition.
How will this Blood Thinner affect the Flow and Viscosity of Blood?
The Blood Thinner will Increase the Flow and Decrease the Viscosity
The Blood Thinner will Decrease the Flow and Increase the Viscosity
The Blood Thinner will Increase the Flow and the Viscosity
The Blood Thinner will Decrease the Flow and the Viscosity
- 10. Multiple Choice
If the Arteries are Narrow and Hard, the Blood Pressure is likely to be _____ than Normal
Higher
Lower
- 11. Multiple Choice
If there is an Increase in Blood Viscosity, then there will be a ________ in Resistance flowing within the Blood Vessels.
Increase
Decrease
- 12. Multiple Choice
An Athlete comes in Dehydrated from the Field because his body lacks ALOT of Fluids.
How does Dehydration affect the Flow and Viscosity of Blood?
Dehydration will Increase the Flow and Decrease the Viscosity
Dehydration will Decrease the Flow and Increase the Viscosity
Dehydration will Increase the Flow and the Viscosity
Dehydration will Decrease the Flow and the Viscosity
- 13. Multiple Choice
The Blood Vessels vasodilate when the Heart Rate increases, like during Exercise.
Why is that?
Vasodilation widens the Vessels allowing more Blood Flow
Vasodilation narrows the Vessels allowing more Blood Flow
Vasodilation widens the Vessels allowing less Blood Flow
Vasodilation narrows the Vessels allowing less Blood Flow
- 14. Multiple Choice

Which statement below explains the "Why?"
You can be predisposed to Health Conditions and be MORE likely to have them if it runs in the Family
You can be predisposed to Health Conditions and be LESS likely to have them if it runs in the Family
You can be predisposed to Health Conditions and it WON'T AFFECT your likelihood of having them if it runs in the Family
