Circulatory System

Front 1

Left atrium

Back 1

the left upper chamber of the heart, receives oxygen-rich blood from the pulmonary veins and pumps blood to pulmonary veins.

Front 2

Right atrium

Back 2

the upper right chamber of the heart, receives deoxygenated blood from the superior and inferior vena cava and then sent to the right ventricle.

Front 3

Coronary arteries:

Back 3

supplies the heart muscle (myocardium) with oxygen rich blood, runs outside the heart and branches out to each side.

Front 4

Coronary veins:

Back 4

takes deoxygenated blood away from the heart and to the coronary sinus.-

Front 5

Anterior vena cava:

Back 5

deoxygenated blood from body to heart, veins from upper body feed into cava, empties into the right atrium-Posterior

Front 6

vena cava:

Back 6

deoxygenated blood to the heart, from the lower body, empties into right atrium-

Front 7

Aorta:

Back 7

largest artery receives oxygen-rich blood from the left ventricle and transports to all parts of the body

Front 8

-Pulmonary artery:

Back 8

the artery carrying blood from the right ventricle of the heart to the lungs for oxygenation

Front 9

.-Pulmonary vein:

Back 9

a vein carrying oxygenated blood from the lungs to the left atrium of the heart

Front 10

Pulmonary trunk:

Back 10

a blood vessel that divides to form the left and right pulmonary arteries, receives blood from right ventricle-

Front 11

Atrioventricular valves:

Back 11

Tricuspid Valve: controls blood flow between right atria and right ventricle.

Front 12

Bicuspid Valve (mitral):

Back 12

controls blood flow between left atria and left ventricle.

Front 13

Chordae tendineae:

Back 13

"heart strings" are tiny white collagenic cords that anchor the valves to the ventricular walls, prevent the atrioventricular valves from opening again once closed. They originate from the papillary muscles

Front 14

Pulmonary Valve:

Back 14

Stands at the opening from the right ventricle in the pulmonary artery trunk. The pulmonary valve moves blood toward the lungs and keeps it from backflowing from the pulmonary artery into the heart.

Front 15

Semi-lunar valves:

Back 15

each of a pair of valves in the heart, at the bases of the aorta and the pulmonary artery, consisting of three cusps or flaps that prevent the flow of blood back into the heart.

Front 16

Aortic Valve:

Back 16

located between the left ventricle and the aorta, lets blood from the left ventricle to be pumped up into the aorta but prevents blood once it is in the aorta from backflowing to the heart.-Septum: separates the left ventricle from the right ventricle.
