Heart Flashcards
Right atrium
Receives deoxy blood
Inferior vena cava
Carries deoxy blood from lower body to right atrium
Atrioventricular valve (AV valve)
Controls direction of blood flow
Right ventricle
Contracts to push blood through semilunar valve into pulmonary artery
Semilunar valve
Controls direction of blood flow
Pulmonary arteries
Carries blood to lungs to get O2 and release O2
Pulmonary vein
Carries oxy blood back to left atrium
Left atrium
Receives oxy blood
Atrioventricular valve
Controls direction of blood flow
Left ventricle
Pushes blood into aorta
Aorta
Largest artery, carries oxy blood to body
Septum
Separated R and L sides; prevents mixing of oxy and deoxy blood
Pericardium
Fluid-filled sac, prevents friction while beating
Superior vena cava
Carries deoxy blood from head to right atrium
Coronary artery
Provides the heart with blood
