Human Heart - Structures and Functions
pulmonary artery
Carries deoxygentated blood from the heart to the lungs for oxygenated-deoxygenated
septum
Divides the right and left chambers of the heart
Myocardium
Muscle of the heart
Aorta
Opens to allow blood to leave the left ventricle-oxygenated
mitral valve
a valve in the heart that guards the opening between the left atrium and the left ventricle-oxygenated
coronary arteries
blood vessels that branch from the aorta and carry oxygen-rich blood to the heart muscle-oxygenated
inferior vena cava
carries blood from lower regions of the body to right atrium-deoxygenated
pulmonary veins
carry the oxygenated blood from the lungs into the left atrium of the heart-oxygenated
pulmonary semilunar valve
controls flow of blood from the right ventricle to the pulmonary artery-deoxygenated
right atrium
deoxygenated blood enters the heart through veins from the tissues-deoxygenated
aortic semilunar valve
opens the way for blood from your lungs to pass from left ventricle into the aorta-oxygenated
right ventricle
pumps blood to the lungs-deoxygenated
left ventricle
pumps oxygenated blood to the body-oxygenated
superior vena cava
receives blood from the head and arms and chest and empties into the right atrium of the heart-deoxygenated
left atrium
receives oxygenated blood from the lungs-oxygenated
tricuspid valve
regulates blood flow between the right atrium and right ventricle-deoxygenated
brachiocephalic artery
supplies head, neck, and right upper limb-oxygenated
ascending aorta
the ascending part of the aorta as it emerges from the left ventricle-oxygenated
descending aorta
the descending part of the aorta that branches into the thoracic and abdominal aorta-oxygenated
papillary muscle
they attach cusps of the atrioventricular valves contract to prevent inversion
chordae tendineae
thin bands of fibrous tissue that attach to the valves in the heart and prevent them from inverting
