Which of the following best describes the connection between cardiovascular disease and age?
As people age, their blood vessels become more elastic leading to less cardiovascular disease.
As people age, the heart becomes more efficient with each pump, increasing cardiac output.
As people age, blood pressure decreases leading to more cardiovascular disease.
As people age, plaque builds up in the arteries increasing vessel resistance, which leads to disease.
What causes atherosclerosis?
high blood pressure
an increase in blood viscosity
accumulation of fatty materials
an increase in blood volume
Which of the following characteristics describe the veins?
move away from the heart
have low blood pressure
distribute blood to body organs
have high blood pressure
What is the direction of blood flow in the circulatory system?

What part of the heart divides the heart into two?
Biscuspid valve

What is the role of veins in the cardiovascular system?
Carry blood away from the heart
Carry blood back to the heart
Carry blood to the lungs
Allows the exchanges of gases, nutrients and wastes between blood and the tissues
What are the 3 main types of blood vessels?
Capillaries, veins, aortas
Capillaries, arteries, platelets
Capillaries, veins, platelets
Capillaries, veins, arteries
Vasodilation can be defined as:
A process in which blood vessels constrict causing a decrease in blood flow
A process in which blood vessels increase their diameter causing an increase in blood flow
A process in which blood vessels constrict causing an increase in blood flow
A process in which blood vessels increase their diameter causing a decrease in blood flow

Name the 4 valves in the correct order that the blood will flow through from the vena cava to the aorta.
aortic semilunar valve, bicuspid (mitral) valve, pulmonary semilunar valve, tricuspid valve
tricuspid valve, bicuspid (mitral) valve, aortic semilunar valve, pulmonary semilunar valve
tricuspid valve, pulmonary semilunar valve, bicuspid (mitral) valve, aortic semilunar valve
bicuspid valve, tricuspid (mitral) valve, aortic semilunar valve, pulmonary semilunar valve
Which artery is the largest and why?
The vena cava is the largest artery because it carries all the body's blood back to the heart
The Pulmonary artery is the largest because it carries all the blood to the lungs
The Aorta is the largest because it carries all the blood out into the body and has to withstand the most force

Purkinje fiber
B points to this vessel

Purkinje fiber
Which valves have chordae tendinae and WHY?
The AV (tricuspid/bicuspid) valves because they need to withstand high pressure from ventricles
the semilunar valves because they need to withstand high pressure from the ventricles
the AV valves because they close under low pressure
the semilunar valves because they close under low pressure
