Anatomy- gross anatomy of heart
what are the 2 destinations of the heart?
body and lungs
systematic circuit
heart- body- heart
pulmonary circuit
heart- lung- heart
what are the 4 chambers of the heart?
right atrium, right ventricle, left atrium, left ventricle
interatrial septum
separates left and right atriums
Intrventricular septum
separates left and right ventricles
the heart is enclosed in a double-walled sac called
the pericardium
right atrium
the right upper chamber of the heart that receives oxygen poor blood from the systemic circuit
capillaries
tiny vessels that connect arteries and veins for diffusion
What is the main function of the heart?
to deliver oxygen to tissues and pickup/remove carbon dioxide
left atrium
Left upper Chamber of the heart that receives oxygenated blood from the pulmonary circuit
what are the 4 great vessels of the heart?
Pulmonary trunk/arteries, pulmonary veins, inferior vena cava/superior vena cava, and aorta`
aorta
The largest artery in the body; brings blood from left ventricle to the rest of the body.
pulmonary veins
The veins that return oxygenated blood from the lungs to the left atrium of the heart.
chordae tendineae
attach the cusps of the tricuspid and bicuspid valves to the papillary muscles of the wall; heart strings
pulmonary trunk
carries blood from right ventricle to pulmonary arteries
artery
carry blood AWAY from heart
veins
carry blood TOWARDS heart
pulmonary arteries
carry deoxygenated blood from the heart to the lungs
endocardium
inside layer; mostly simple squamous epithelium
ventricles are
lower chambers
right and left ventricles
lower chambers of the heart that pump blood
myocardium
middle layer of the heart, mostly muscle
epicardium
outer layer of the heart
the right side of heart is?
oxygen poor and co2 rich
the left side of heart is?
oxygen rich and co2 poor
what are the 2 pumps of the heart?
pulmonary and systemic circuit
right ventricle
pumps deoxygenated blood to the lungs
left ventricle
pumps oxygenated blood to the body
What are the 4 valves?
tricuspid, pulmonary, mitral, aortic
artias are
upper chambers
right and left atrium
upper chambers of the heart; receives blood from vessels
aorta valve
valve between left ventricle and aorta
pulmonary valve
valve between right ventricle and pulmonary trunk
bicuspid valve
valve between the left atrium and the left ventricle.
tricuspid valve
valve between the right atrium and the right ventricle
inferior vena cava
vein that brings oxygen-poor blood from the lower part of the body to the right atrium
superior vena cava
vein that carries deoxygenated blood from the upper half of the body to the heart's right atrium
