Cardio Overview Part 2 Flashcards
What type of circulation includes the following:
Pulmonary arteries and veins
Pulmonary circulation
What type of circulation includes the following:
Blood vessels between the aorta and venae cavae
Systemic circulation
What type of circulation includes the following:
Coronary arteries and veins
Supplies blood to heart itself
Coronary circulation
What type of pressure is the following:
Left ventricle contracts and ejects the blood into aorta- aorta becomes distended with blood- aortic blood pressure = peak value
Systolic aortic pressure
What type of pressure is the following:
Between ejections, blood flows out of aorta into downstream arteries- outflow of blood from aorta = aortic pressure to decrease
Minimal value of aortic blood pressure reached before next cardiac ejection =
Diastolic aortic pressure
What type of pressure is the following:
Average value of pulsatile blood pressure in aorta
Mean aortic pressure
What is the volume of blood pumped each minute by one ventricle & cardiac outputs of the left and right ventricles are almost equal
Cardiac output
Which circulation is represented by the mean aortic pressure?
Systemic circulation
What pressure is the following:
Difference between mean aortic pressure and mean venae cavae pressure?
Systemic perfusion pressure
What is the perfusion rate for the systemic circuit typically?
95mm Hg
What pressure is the following:
Difference between mean pulmonary artery and pulmonary veins?
Pulmonary perfusion pressure
Pulmonary perfusion pressure of blood flow through lungs?
8mm Hg
The perfusion pressure for systemic circulation is _______ than the perfusion pressure for the pulmonary circulation
Greater
Which circulation is referred to as the high-pressure, high-resistance side of the circulation?
Systemic circulation
Which circulation is referred to as the low-pressure, low-resistance side of the circulation?
Pulmonary circulation
Blood pressure is measured at the heart level with reference to ____________ pressure
Atmospheric
Which vessels of the systemic circulation distribute the most blood volume?
Venues and veins
What is the most numerous, smallest inside diameter, largest cross-sectional area, smallest length and lowest velocity of blood flow blood vessels of systemic circulation?
Capillaries
Which vessel of the systemic circulation has the largest inside diameter and smallest mean blood pressure?
Venae cavae
Which vessel of the systemic circulation has the highest mean blood pressure and velocity of blood flow, and longest in length?
Aorta
