HEART PARTS & RANDOM INFO
2 entrance valves of the heart
tricuspid
bicuspid
separates right and left sides of heart
septum
only way to oxygenate the blood
alveoli & capillaries
the apex is located here
on the diaphragm
the build-up of fat deposits on the walls of the arteries is a major cause of
arteriosclerosis
fibrous outer fluid-filled layer that covers the heart and separates it from the contents in the chest cavity
pericardium
pointed end of heart
apex
as blood returns to the heart from the body, it enters
right atrium
this is the upper border of the heart and it is broad in shape
base

pericardium
function of the heart
pump sufficient amounts of blood
to all of the cells of the body

this is heart pain from the lack of circulation to coronary arteries
angina

in the mediastinum
the heart is classified as
a hollow, muscular organ
blood flows from the left atrium to the left ventricle through the
mitral/bicuspid valve
the myocardium gets its nurishment from the
coronary arteries
when the heart rate gores down to 40-60, the impulse is probably generated in the
AV node
size of a normal heart
size of a fist
the valves of the heart are made of
endocardium
this blood vessel leave the heart and carries blood to all parts of the body
aorta
if blood supply to the myocardium stops
the area dies
thickest layer of the heart
myocardium
