Question | Answer |
Diastole | phase of a cardiac cycle when a heart chamber wall relaxes |
cardiac output | amount of bllood per minute pumped by the heart |
Endocardium | inner lining of heart chambers |
Epicardium | outside of pericardium. on surface of heart |
ischemia | deficiency of blood to a body part. |
mitral valve(bicuspid) | between left atrium and left ventricle. |
myocardium | heart muscle tissue |
systole | phase of cardiac cycle when a heart chamber wall contracts. |
Epicardium | outer layer of the heart that reduces friction from surrounding organs |
Endocardium | covers heart valves and lines heart chambers. |
Cardiac Veins | parallel to coronary arteries. Drain into coronary sinus. Empties into right atrium. Located on posterior side of heart. |
3 layers of heart blood vessels | tunica intima(endothelium), Tunica media, and tunica externa |
Tunica media | middle layer of heart blood vessel. Thickest layer in arteries. |
Tunica externa | Outer layer of heart blood vessel. This is the thickest layer in a vein. |
Portal circulation | carries blood drained from the stomach, intestines, and spleen to the liver. |
P-Wave | atria depolarization. Sa-nod spreads impulse |
QRS Complex | ventricular depolarization. Atria repolarization. |
T-Wave | Ventricular repolarization. |
Parasympathetic nerve impulses(in relation to heart rate) | causes heart rate to slow down. |
sympathetic nerve impulses(in relation to heart rate) | causes heart rate to speed up. |
High levels of serum potassium(K+)(in relation to cardiac cycle) | causes the heart to be excitable |
Calcium(Ca2+) (in relation to cardiac cycle) | important to cardiac muscle contraction. If too much is present, prolonged contractions. Too little, heart becomes weak. |
First heart sound(s1 or LUB) | Caused by the closure of the atrioventrical valves. |
Second heart sound(s2 or DUB) | caused by the closure of the semilunar valves |
