HEART ANATOMY - Coggle Diagram
HEART ANATOMY
surface anatomy
shaped roughly like a cone
consists of four muscular chambers
pumping chambers: ventricles
deliver blood to ventricles: Atria
the apex is formed by the tip of left ventricle
anterior surface: shaped by the right atrium and ventricle
left atrium and ventricle lie more posteriorly
four border
internal structure
four major valves
direct blood flow - prevent backward leakage
atrioventricular valves (AV) - van nhĩ thất
tricuspid valve: van 3 lá - stops blood from the returning into the right atrium from right ventricle
mitral valve - van 2 lá - stops blood from the returning into the left atrium from left ventricle
semilunar valves: van bán nguyệt
pulmonic valves
aortic valve
separate the ventricle from great arteries
are attached to the fibrous cardiac skeletion
is composed of dense connective tissue
endocardium
a single layer of endothelial celss
lines the surface of heart valves and the interior surface
myocardium
thickest layer of the heart and consists bundles cardiac muscle cells
external to the myocardium
is a layer of connective tissue and adipose tissue through which pass the larger blood vessels and nerves that supply the heart muscle.
epicardium
the outermost layer of the heart
another term for visceral pericardium
