⫸ Location of Hart in mediastinum and thorax. Answer: Apex -
apical impulse PMI
Left and right atria - smaller and superior
Left and right ventricles Dash larger and inferior separated by intro
ventricular septum
⫸ Right atrium/ventricle. Answer: Right atrium delivers
deoxygenated blood ejected through the tricuspid into right ventricle
Right ventricle ejects blood through pulmonary semi lunar valve to
trunk of pulmonary arteries
⫸ Left atrium/ventricle/. Answer: Left atrium receives oxygenated
blood and pumps through mitral valve into left ventricle
Left ventricle is egg shaped most muscular, permits pumping of blood
through aortic semi lunar valve into aorta, females is smaller
⫸ systole and diastole. Answer: systole= contraction
,diastole=ventricular relax
⫸ AV valves. Answer: tricuspid- separate atrium from ventricle
between the right
Mitral - thicker, separates atrium from ventricle left, S1 sound
⫸ Semi-lunar valves. Answer: pulmonary -separate right ventricle
from trunk of pulmonary artery
aortic-separates left ventricle from aorta
comptenent vlaves=no regurgitation
⫸ Heart sounds. Answer: s1: lub- AV vales close, vents fill
s2: dub- aortic/pulmonic close
s3 ans s4- usually abnormal, sometimes healthy
s4 before s1=atrial gallup
s3 after s2=vent gallup
, ⫸ s4 sounds consider. Answer: may be heard in children, athletes,
healthy elderly individuals without cardiac disease
According to pitch duration and intensity
⫸ s3 sounds consider. Answer: Might be hurting children, young
adults, pregnant females
AV valves open, blood flow into ventricles may cause vibrations
⫸ S3 and S4 Soundz. Answer: Associated with MI or HF,
S3 occurs when the ventricles reach elastic limit, blood flow from
atrium to slow
S4 sounds are associated with active atrial contractions that cause late
ventricular filling
⫸ Click and snaps. Answer: Clicks and snaps may be heard in
valvular disease
Opening snap is mitral stenosis
Ejection clicks occur in damaged permanently and aortic valve's
