Where is the heart location?
Left of the midline in the thoracic cavity
What are the two layers of the pericardium?
Fibrous and serous pericardium
What is the blow flow cycle?
Deoxygenated blood goes in the superior and inferior vena cava, into right atrium, into the right ventricle, through the pulmonary trunk through the left and right pulmonary artery. The oxygenated blood goes into the pulmonary veins into the left atrium, to the left ventricle, which goes into the aorta.
What is the right AV valve called?
Triscuspid
What is the left AV valve called?
Mitral valve
What are the coords connecting the papillary muscle and the right ventricle?
Tendinous cords
What are the two major arteries?
The right and left coronary arteries
What is the artery on the right more in the center?
Posterior descending artery
What splits off the right coronary artery?
Right marginal artery
What is the artery right under the coronary artery?
The left circumflex artery
What left artery is more on the back?
The left marginal artery
What left artery is more towards the center?
Left anterior descending artery
What vein is under the superior vena cava?
The anterior cardiac vein
What is the lowest under the superior vena cava?
Small cardiac vein
What is under the left atrium?
The great cardiac vein
What connects most of the veins?
The coronary sinus
What vein runs down the center?
The middle cardiac vein
What does systole mean?
Contraction
What does diastole mean?
Relaxation
What is the strove volume formula?
SV = End-diastolic volume - End-systolic volume
What is the formula for CO?
CO= heart rate (HR) x Stroke volume (SV)
What is the cardiac resting potential?

What happens during depolarization?
Na open and Ca open
What happens during early repolarization?
K efflux and Na close
What happens during plateau phase?
K and Ca equilibrium
What happens during repolarization?
Ca close and K influx
