cardiac test

what are the receiving heart chambers called? the discharging chambers? where are they located?

atria, ventricles,

where does blood go after leaving the left ventricles?

aorta

what is pulmonary circulation?

leaves right side of heart, goes to the lungs, and returns back to the heart

what heart wall is the thickest and why?

left ventricle because it’s the systemic pump

what does systole mean?

heart contraction

what is stroke volume?

volume of blood pumped out with each heart beat

what type of blood vessel is often used for blood draws?

veins

what is the purpose of valves?

prevents back flow of blood

140/90 or above

what blood vessels does oxygen rich blood travel through to get back to the left atrium?

pulmonary veins(they do have oxygen rich blood)

what blood vessel carries blood toward the heart?

veins

what chamber of the heart contains the SA node?

right atrium

what chamber of the heart pumps blood into the pulmonary arch?

right ventricle

what chamber of the heart is the discharging chamber on the left side?

what type of blood vessels is the aorta?

artery

what are tiny beds of vessels called?

capillaries

how are arteries, capillaries, and veins structurally different?

arterial walls are thicker, stronger, higher pressure

veins are thinner, weaker, and low pressure

capillaries are very very thin walls

aortic valve stenosis would affect which type of circulation; pulmonary or systemic? why?

systemic; aorta goes to the whole body
