Heart Structures Flashcards
oxygen-rich side
left
oxygen-poor side
right
carry blood away from the heart
arteries
carry blood towards the heart
veins
pulmonary
lungs
systemic
body
prevent back-flow of blood
valves
largest artery in the human body
Aorta
carries oxygen-rich blood to the systemic circulation
Aorta
begins in the left ventricle
Aorta
upper chamber of the heart; oxygen-rich blood enters from the lungs (pulmonary circulation)
Left Atrium
blood vessels that carry oxygen-rich blood from the lungs to the left atrium
Pulmonary veins
AV valve that allows blood to flow from left atrium to left ventricle;
Bicuspid valve
semilunar valve that prevents backward flow of blood from aorta to left ventricle
Aortic valve
lower chamber of the heart; oxygen-rich blood leaves this chamber to go out to the systemic circulation (body);
Left ventricle
chamber with the thickest muscular layer
left ventricle
separates the left and right side of the heart
Septum
prevents oxygen-rich blood from mixing with oxygen-poor blood
septum
lower chamber of the heart; oxygen-poor blood leaves this chamber to go out to the lungs
Right ventricle
vessel by which oxygen-poor blood is returned to the heart from the lower body
Inferior Vena Cava
vessel by which oxygen-poor blood is returned to the heart from the upper body
Superior Vena Cava
AV valve that allows blood to flow from right atrium to right ventricle;
Tricuspid valve
prevents blood from flowing backwards from ventricle to atrium
tricuspid and Bicuspid valve
semilunar valve that prevents backward flow of blood from pulmonary trunk (arteries) to right ventricle
Pulmonary valve
upper chamber of the heart; oxygen-poor blood enters from the body
Right atrium
blood vessels that carry oxygen-poor blood from the right ventricle to the lungs
Pulmonary arteries
