The Structure of a Human Heart Flashcards
Aorta
The main artery that carries blood away from the heart to the body (oxygen)
Pulmonary artery
Blood vessel that carries O2 poor blood from the right side of the heart to the lungs (de-oxygenated)
Aortic Valve
three leaflet valve between the left atrium and ventricle. ( de-oxygenated)
Mitral valve
two leaflet valve between the left atrium and ventricle (oxygenated)
Left atrium
Receives oxygen-rich blood from the lungs and pumps it into the left ventricle. (oxygenated)
Left ventricle
Pumps oxygen rich blood to the rest of the body via the aorta. ( oxygenated)
Right ventricle
Pumps oxygen poor blood to the lungs. ( de-oxygenated).
Tricuspid valve
Three leaflet valve between the right ventricle and the pulmonary artery.
Right atrium
Receives oxygen-rich blood from the lungs and pumps it into the right ventricle (de-oxygenated blood)
Pulmonary veins
Blood vessels that carry oxygen-rich blood from the lungs to the heart (oxygenated)
Pulmonary valve
Three leaflet valve between the right atrium and ventricle.
Superior vena cava
A major vein that carries blood from the upper body (head, chest, arms) to the heart
Order the blood flows
Aorta –> body –> vena super cava inferior –> right atrium–> tricuspid valve –> right ventricle –> pulmonary valve –> lungs (drop CO2 pick up O2) –> pulmonary veins–> left atrium –> mitral valve (aka bicuspid valve) –> left ventricle –> aortic valve –aorta
