Select one of the following:

Central Venous Pressure (measured from the height of the jugular vein to “see how high the column of blood is in the jugular vein and above that it’s collapsed”)
Cardiac Venous Pressure (measured from the height of the jugular vein to “see how high the column of blood is in the jugular vein and above that it’s collapsed”)
Central Ventricular Pressure (measured from the height of the jugular vein to “see how high the column of blood is in the jugular vein and above that it’s collapsed”)
Cardiac Ventricular Pressure (measured from the height of the jugular vein to “see how high the column of blood is in the jugular vein and above that it’s collapsed”)

Question 3 of 9

4

If Cardiac Output (CO) falls 50%, BP will also fall 50% (because BP = CO * TPR). >> Reduced baroreceptor firing >> increased sympathetic activity. This results in which of the following:
(after a while, this is useless, but of benefit immediately)

Select one or more of the following:

Increased HR
Decreased HR
Increased contractility
Decreased contractility
Selective arteriolar vasoconstriction
Selective arteriolar vasodilation
Venoconstriction
Venodilation

Explanation

Question 4 of 9

1

ANF is a peptide hormone stored in atrial cells of the heart. It inhibits Na+ reabsorption in Kidney and promotes Na+ and H2O loss. This is a way that the RAAS thing works. ANF = ??

Select one of the following:

Atrial Naturetic Factor
Arterial Naturetic Factor
Atrial Natiuric Factor
Arterial Natiuric Factor

Explanation

Question 5 of 9

1

Which of the following are pathways by which the heart responds to reduced CO?

Select one or more of the following:

Baroreceptor/sympathetic response
RAAS response
Hypertrophy of the heart

Explanation
