Cardiovascular: Hemodynamics and Pressures

Question 1

what is the flow through the right side of the heart?

Answer 1

superior/inferior vena cava – RA – tricuspid valve – RV – pulmonary valve – pulmonary arteries – lungs

Question 2

is the blood on the right side of the heart oxygenated or deoxygenated?

Answer 2

deoxygenated

Question 3

what is the blood flow through the left side of the heart?

Answer 3

pulmonary veins – LA – mitral valve – LV – aortic valve – aorta – body

Question 4

is the blood in the left side of the heart oxygenated or deoxygenated?

Answer 4

oxygenated

Question 5

what are the purpose of valves?

Answer 5

ensure one way flow

Question 6

what is the function of lymph vessels in the capillary bed?

Answer 6

they get rid of the extra fluid, if they don’t edema will occur

Question 7

why is it important for mean arterial pressure (MAP) to be above 60?

Answer 7

to diffuse organs properly

Question 8

how does increased arterial resistance cause increased pressure?

Answer 8

decreases compliance of blood vessels which makes it harder for blood to flow so more pressure is needed to overcome
