Blood Flow

The arrow indicates the

• Right ventricle

• Aorta

• Right atrium

• Atrium

Name the part.

• Pulmonary vein

• Right atrium

• Aorta

• Pulmonary artery

What does the letter A represent?

• Superior vena cava

• Inferior vena cava

• Aorta

• Pulmonary artery

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.

Select ALL of the Following Factors that CAN affect Blood Flow.

• Blood Pressure

• Heart Rate

• Respiratory Rate

• Viscosity

• Blood Sugar

Type of blood vessels taking blood AWAY from the Heart

• Venules

• Veins

• Capillaries

• Arteries

Type of blood vessels taking blood TO the Heart

• Venules

• Veins

• Capillaries

• Arteries

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.

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.

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
