Right side of the heart pumps to... ......ANSWER........Lungs
Left side of heart pumps... ......ANSWER........simutaneously to
body
Septum ......ANSWER........wall that separates two pumps
atrioventricular valves ......ANSWER........separate atria and
ventricles
heard at apex, located at bottom of heart: 5th rib intercostal
space
,age 2 of 61
Apical pulse is also called ......ANSWER........Mitral
area/PM/Apex
Right AV valve = ......ANSWER........tricuspid valve, 5th intercostal
space at left sternal border
Left AV valve = ......ANSWER........Mitral valve, 5th intercostal
space at left midclavicular line
Semilunar (SL) valves ......ANSWER........between ventricles and
arteries
3 cusps that look like half moons
heard at BASE, located at TOP of heart
pulmonic valve ......ANSWER........located on right side of heart,
2nd L intercostal space
,age 3 of 61
aortic valve ......ANSWER........located on left side of heart, 2nd R
intercostal space
Diastole phase ......ANSWER........ventricles relax, heart fills with
blood
2/3 of cycle
AV valves (tricuspid and mitral) are OPEN
pressure in atria is higher than in ventricles.
1st filling phase is called early or protodiastolic filling.
2nd filling is called presystole or atrial systole
Systole phase ......ANSWER........blood pumped from ventricles
and fills pulmonary and systemic arteries
1/3 of cardiac cycle
, age 4 of 61
ventricular pressure is now HIGHER than that of atria, causing
atria to close. After blood ejection, pressure falls in ventricles.
When pressure falls below pressure in aorta, some blood flows
backward towards ventricle, causing aortic valve to shut.
S1 or Lub ......ANSWER........closer of AV valve
S2 or Dub ......ANSWER........closure of semilunar valve
S3 heart sound ......ANSWER........↑ventricular filling pressure
(e.g., mitral regurgitation, HF), common in dilated ventricles.
VIBRATIONS heard over chest. A gallop.
Occurs immediately after S2 (LUB DUB DUB). May be early sign
of heart failure.
S4 heart sound ......ANSWER........occurs at end of Diastole, at
presystole. HEARD BEST AT APEX w/ pt turned to LEFT LATERAL
