True
False
Which side of the heart carries oxygenated blood?
Left
Right
When the heart contracts, it squeezes the blood out of the ventricle and into the arteries. This is called the ______ phase of the hearts contraction.
Systole
Diastole
Cisily
Circulatory
The amount of blood ejected by the left ventricle in one contraction/heart beat is called what:
Heart rate
Stroke Volume
Cardiac Output
Systemic Circulation
A measure of the volume of blood ejected from the left ventricle of the heart per minute is called:
Heart Rate
Stroke Volume
Cardiac Output
Systemic Circulation
During an increasing intensity exercise, which component will plateau at 40-50% of max exercise capacity.
Heart Rate
Stroke Volume
Cardiac Output
Systemic Circulation
Blood transports oxygen from the lungs and heart to the working (a) , and then removes metabolic by-products such as carbon dioxide from muscle sites.
_______ results in less blood moving through capillaries, and more blood being redirected to areas

Pre capillary sphincters
___________ is elevated body temperature due to failed thermoregulation
Hyothermia
Hyperthermia
Increased _______________; is the difference in the amount of oxygen in the arteries with the amount of oxygen in the veins.
Muscle Oxygen Intake (MO-I)
Arteriovenous Oxygen Difference (a-VO2 diff)
Arteriol Delivery Effect (AD-eff)
Carbon Dioxide Extract (CDE)
Arterio - venous oxygen difference (a-Vo2 diff) is greatest at:
A/ maximal exercise
B/ sub maximal exercise
C/ rest
D/ none of the above – it remains constant
Maximal exercise
Submaximal exercise
Rest
It remains constant
After leaving the heart the blood will take the following pathway:
arteries - arterioles - (a) - venules - veins.
