WORKSHEET QUESTIONS
What branch of the autonomic nervous system regulates
vasoconstriction of arterioles?
In times of stress, why do skeletal muscles arterioles vasodilate?
The blood vessels to the brain and heart never vasoconstrict - why?
Kidneys can reabsorb water (into the bloodstream). What effect does
this have on blood pressure?
When you cut a vein, blood flows out evenly, but an artery spurts –
why?
Why must the aorta have elastic walls?
If the CO is 5000 ml/min, what % of the total blood volume is pumped
per minute?
How many ml of blood is pumped from each ventricle in a heart
beat?
If the SV is too low, how would an increase in heart rate
compensate?
If the AV node is damaged, what would happen?
Why does arteriosclerosis (hardening of the arteries) increase blood
pressure?

2 ways to:
Click for answer

Locally vasodilate (autoregulation)

Increase heart rate

Decrease blood pressure
Vasodilation, decrease HR

Increase EDV
Execise, increase venous
return to RA

Monitor blood pressure
Aortic and carotid
baroreceptors

Increase resistance to blood flow
More blood vessels,
vasocontrict

Send blood out of heart
Nitric oxide and low O2 in cells
Epinephrine, exercise
Through RA and RV

The only layer found in capillaries
A single layer of endothelium
A middle coat, composed of smooth muscle and elastic
fibers
Supporting, protective layer
Plays a role in blood pressure regulation
In direct contact with the lumen
Thicker in an artery than in a vein
Can vasoconstrict
Thicker in artery, thinner in vein
Valves in veins
Provides elasticity to elastic arteries
