B.Hypertension
C.Heart valve stenosis
D.Back flow of the valves
E.Both A and B

Stenosis restricting the opening of a heart valve, causing turbulence as
bloodflows through it.
Valve insufficiency (or regurgitation) allows backflow of blood when
theincompetent valve is supposed to be closed. (Found on the last slide in 11C
powerpoint)

C. Block sodium channel
D. Simulate sodium channel Right Ans - C. Block sodium channels (found in
PowerPoint 11C slide 11)
QRS complex is to depolarization of the ventricle, as P wave is to ____
A. Depolarization of AV node
B. Depolarization of the atria
C. Repolarization of the ventricles
D. Period of rest Right Ans - B. Depolarization of the atria (think of how the
charge is dispersed)
Glucose in the urine shows worry for
A. Hypoglycemia
B. Kidney disease
C. Nothing its normal
D. Hyporglycemia Right Ans - B. Kidney disease
Function of platlets
A. Make antibodies

The collecting tubule
A. Secretes protein
B. Secretes potassium
