PPT 4 EXAM 3: blood pressure Flashcards
Select all the statements that are correct regarding blood pressure.
A.
It is essential to keep a pressure gradient inside the cardiovascular system to ensure proper blood flow.
B.
Veins have a higher average blood pressure than arteries.
C.
In the cardiovascular system, blood pressure is at its highest in the aorta and gets down to 0 mm Hg in the right atrium.
D.
Larger veins experience a higher pressure than venules.
E.
Blood pressure is the force applied by blood, during the cardiac cycle, on the walls of arteries.
A.

C.

E.
Blood pressure is the force applied by blood, during the cardiac cycle, on the walls of arteries.
Normal blood pressure is around 120/80 mmHg.
True or False.
In this result, 120 represents the pressure found in arteries when the ventricles contract and 80 represents the pressure found in arteries when the heart relaxes.
true
what is the name of the sensors found in important arteries that detect blood pressure?
baroreceptors
For each statement below, determine if the blood pressure will increase, decrease or remain the same.
1) The heart rate goes from 60 beats a minute to 100 beats a minute.
2) When at rest, the heart rate decreases.
3) Arteries and veins dilate.
4) Someone cut an artery and suffers an important bleeding.
1) increase in BP
2) decrease in BP
3) decrease in BP
4) decrease in BP
For each statement below, determine if the blood pressure will increase, decrease or remain the same.
5) The left ventricles contracts with more strength.
6) Arteries and veins vasoconstrict.
7) More water got attracted inside blood vessels.
8) During a heart attack, a quarter of the left ventricle’s contractile cells do not respond anymore
9) The fight-or-flight response cause the heart rate to increase and the cardiac muscle to pump harder; the cardiac output increases.
5) increase in BP
6) increase in BP
7) increase in BP WHY
8) decrease in BP
9) increase in BP
