Flashcards in Vocab Deck (24):
1

Atherosclerosis

plaque accumulation within the lumen of the artery

2

What is associated with Atherosclerosis?

HTN, stroke, angina, heart attack, renal failure

3

CHF is usually caused by these 2 things:

NTN, AMI

4

Left side of the heart is:

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

5

Septum

wall

6

AV valves:

tricuspid 3 flaps
mitral (bicuspid) 2 flaps

7

Semilunar valves:

aortic valve
pulmonic valve

8

S1 heart sound is what?

"lubb" closing of the AV valves

9

S2 heart sound is what?

"dubb" closing of the semilunar valves

10

Stenosis

thickening or hardening of tissue

11

Anastomoses

When the body creates its own bypass

12

Poiseuille's Law

Amount a vessel can transport is related to its diameter

13

Heart beat is what wave to what wave?

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

14

Atrial kick is related to what % of cardiac output?

30%

15

Stroke volume:

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

16

Preload:

pressure in the filled ventricle at the end of diastole

17

Frank-Starling Law

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

18

Frank-Starling Law works on what?

Inotropic effect

19

Systemic Vascular Resistance

resistance to flow of blood determined by the vessel diameter

20

Hypertrophy

process of thickening of cardiac chamber wall

21

Excitability

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

22

Conductivity

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.

23

Automaticity

ability of cardiac pacemaker cells to spontaneously initiate an electrical impulse

24

Contractility

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