plaque accumulation within the lumen of the artery

Question 2

What is associated with Atherosclerosis?

Answer 2

HTN, stroke, angina, heart attack, renal failure

Question 3

CHF is usually caused by these 2 things:

Answer 3

NTN, AMI

Question 4

Left side of the heart is:

Answer 4

Thicker than the right because the left pumps the blood to the body.

Question 5

Septum

tricuspid 3 flaps

mitral (bicuspid) 2 flaps

Question 7

Semilunar valves:

Answer 7

aortic valve

pulmonic valve

Question 8

S1 heart sound is what?

Answer 8

“lubb” closing of the AV valves

Question 9

S2 heart sound is what?

Answer 9

“dubb” closing of the semilunar valves

Question 10

Stenosis

Answer 10

thickening or hardening of tissue

Question 11

Anastomoses

Answer 11

When the body creates its own bypass

Question 12

Poiseuille’s Law

Answer 12

Amount a vessel can transport is related to its diameter

Question 13

Heart beat is what wave to what wave?

Answer 13

end of the T wave to the end of the T wave

Question 14

Atrial kick is related to what % of cardiac output?

Answer 14

30%

Question 15

Stroke volume:

Answer 15

amount of blood ejected from the ventricle with each hear beat. (Basically your heart beat)

Question 16

Preload:

Answer 16

pressure in the filled ventricle at the end of diastole

Question 17

Frank-Starling Law

Answer 17

greater the volume of blood in the heart during diastole the myocardium will stretch causing a more forceful contraction.

Question 18

Frank-Starling Law works on what?

Answer 18

Inotropic effect

Question 19

Systemic Vascular Resistance

Answer 19

resistance to flow of blood determined by the vessel diameter

Question 20

Hypertrophy

Answer 20

process of thickening of cardiac chamber wall

Question 21

Excitability

Answer 21

ability of cardiac muscle cells to respond to an external stimulus. “When David gets excited, Wes gets irritated.”

Question 22

Conductivity

Answer 22

ability of cardiac cells to receive an electrical stimulus and conduct that impulse to an adjacent cell. 1 cell fires another cell accepts and continues.

Question 23

Automaticity

Answer 23

ability of cardiac pacemaker cells to spontaneously initiate an electrical impulse

Question 24

Contractility

Answer 24

ability of cardiac cells to shorten causing muscle contraction in response to electrical stimulus
