aortic valve
Give this one a try later!
located on left side of heart, 2nd R intercostal space
The function of the pulmonic valve is to:
a. Divide the left atrium and left ventricle
b. Guard the opening between the right atrium and right ventricle
c. Protect the orifice between the right ventricle and the pulmonary artery
d. Guard the entrance to the aorta from the left ventricle

Cardiac Output (CO)

Amount of blood pumped in 1 minute (4-6 L)

The ability of the heart to contract independently of any signals or stimulation is due
to:
depolarization.
automaticity.
conduction.
repolarization.

Automaticity
The heart can contract by itself, independent of any signals or stimulation
from the body; this property is termed automaticity. Depolarization is the
reversal of the resting potential in excitable cardiac muscle cell membranes
when stimulated. Conduction is the process by which an electrical impulse
is transmitted through the heart. Repolarization is the process by which the
membrane potential of a cardiac muscle cell is restored to the cell's resting
potential.
Coolness occurs, avoid compression stockings b/c further constrict blood flow

tricuspid regurgitation
Give this one a try later!
backflow of blood through incompetent tricuspid valve into the right atria
◦Objective: Engorged pulsating neck veins, liver enlarged.
◦Murmur: Pansystolic
◦Best Heard: left lower sternal border
A murmur is heard after S1 and before S2. This murmur would be classified as:
a. Diastolic (possibly benign)
b. Diastolic (always pathologic)
c. Systolic (possibly benign)
d. Systolic (always pathologic)
