• Capillaries

• Arteries

Type of blood vessels taking blood TO the Heart

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.

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.

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

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.

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

If the Arteries are Narrow and Hard, the Blood Pressure is likely to be _____ than Normal

• Higher

• Lower
