-
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”)

Pregunta 2
Pregunta
"Starling curves" (Ventricular function curves).
Which is which?
Respuesta
-
Normal
-
Sympathetically stimulated (eg exercise)
-
Following heart attack
Pregunta 3
Pregunta
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)
Respuesta
-
Increased HR
-
Decreased HR
-
Increased contractility
-
Decreased contractility
-
Selective arteriolar vasoconstriction
-
Selective arteriolar vasodilation
-
Venoconstriction
-
Venodilation
Pregunta 4
Pregunta
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 = ??
