APHY 164 - CVS Heart Anatomy Diagram | Quizlet

TERM

Aorta

DEFINITION

Carries oxygenated blood from the left ventricle of the heart to the rest of the body

TERM

Superior Vena Cava

DEFINITION

Large vein that carries deoxygenated blood from the upper body to the right atrium

TERM

Pulmonary trunk (artery)

DEFINITION

Delivers deoxygenated blood from the right ventricle to the lungs

TERM

Pulmonary veins

DEFINITION

Deliver oxygenated blood from the lungs to the left atrium

TERM

Right Atrium

DEFINITION

Receives deoxygenated blood from the superior vena cava, inferior vena cava, and coronary sinus

TERM

Tricuspid Valve

DEFINITION

atrioventricular valve, three cusps, prevents the back flow of deoxygenated blood from the right ventricle into the right atrium during ventricular contraction

TERM

Chordae Tendineae

DEFINITION

thin bands of fibrous tissue that anchor the atrioventricular valves to the papillary muscles in the ventricles, prevent valves from inverting

TERM

Bicuspid (Mitral) Valve

DEFINITION

atrioventricular valve, two cusps, prevents the back flow of oxygenated blood from the left ventricle into the left atrium during ventricular contraction

TERM

Pulmonary valve

DEFINITION

semilunar valve, prevents the backflow of deoxygenated blood from the pulmonary trunk into the right ventricle during ventricular relaxation

TERM

Left atrium

DEFINITION

receives oxygenated blood from the lungs via the pulmonary veins

TERM

Right ventricle

DEFINITION

pumps deoxygenated blood to the lungs via the pulmonary trunk/arteries

TERM

Left ventricle

DEFINITION

pumps oxygenated blood to the body via the aorta

TERM

Inferior vena cava

DEFINITION

Large vein that carries deoxygenated blood from lower regions of the body to right atrium

TERM

Aortic valve

DEFINITION

semilunar valve, prevents the backflow of oxygenated blood from the aorta into the left ventricle during ventricular relaxation
