Heart Anatomy Flashcards
Left ventricle
bottom left chamber of the heart that receives oxygenated blood from lungs
Right atrium
top right chamber of the heart that receives deoxygenated blood from the body
Tricuspid valve
AV valve; between right atrium and ventricle; prevents club bouncer
Papillary muscle
bundles of cardiac muscle; attached to ends of chordae tendineae; contract to tense chordae tendineae; prevents valve cusps from moving into atria
Mitral (bicuspid) valve
AV valve; between left atrium and ventricle; prevents backflow into left atrium during ventricular contraction
Systemic circulation
pumps oxygen-rich blood to the body and returns deoxygenated blood back to the heart to be sent out for to the lungs to be exchanged for oxygen
Pericardium
a multilayered membrane that forms a protective sac around the heart
Left atrium
chamber of the heart, receives blood from pulmonary veins
Aorta
largest artery in the body, carries blood from the left ventricle to the rest of the body through the systemic pathway
Right coronary artery
Located on the surface of the heart, responsible for carrying oxygen and nutrients to the surface of the heart.
Septum
muscular wall that separates left and right ventricles
Arteries
blood vessels that carry oxygenated blood away from the heart
Veins
blood vessels that carry deoxygenated blood back towards the heart
Myocardial Infarction
A heart attack (MI) usually occurs when a blockage in the coronary artery prevents blood flow to the heart tissue.
What is the purpose of a valve?
To prevent backward flow of blood
