what are the three layers of the pericardial sac

fibrous pericardium, parietal pericardium, visceral pericardium

outermost layer of myocardial tissue

Epicardium

myocardial middle layer

myocardium

innermost layer of myocardial tissue

endocardium

the tricuspid valve separates the

right ventricle & atrium

what valve separates the right ventricle and the pulmonary artery

pulmonary valve

what is the only artery to carry deoxygenated blood

pulmonary

contains the interatrial pathway known as Bachmann’s Bundle

Left atrium

Separated by the mitral valve also known as the bicuspid valve

left ventricle and atrium

Separates the atriums from the ventricles

Atrioventricular Septum

what is the only thing to pass through the Atrioventricular Septum

Bundle of HIS

separates the ventricles

Interventricular septum

this septum is nonconductive

Atrioventricular Septum

this septum is conductive

Interventricular septum

RCA stands for

Right Coronary Artery

LCA stands for

LEFT CORONARY ARTERY

The Widowmaker AKA

LEFT ANTERIOR DESCENDING

the LCA that wraps around to the posterior side

LEFT CIRCUMFLEX ARTERY

The amount of blood the heart pumps through the circulatory system in a minute.

CARDIAC OUTPUT

Average Cardiac Output =

4.9L

Average Stroke volume =

70mL

Average heart rate =

70 bpm

Cardiac output =

Stroke volume X Heart rate (SV X HR=CO)

Volume of blood in the LV (End Diastolic Volume)

PRELOAD

Pressure that the ventricle must pump against to eject the blood

AFTERLOAD

Inotropic is

the strength of contractions

Chronotropic is related to the

heart rate

Dromotropic refers to the

speed of electrical impulse
