Anatomy Of The Heart

Front 1

Chordae Tendineae

Back 1

Attaches AV valves to papillary muscles. The chordae tendineae (tendinous chords), or heart strings, are cord-like tendons that connect the papillary muscles to the tricuspid valve and the mitral valve in the heart

Front 2

Papillary muscles

Back 2

muscular extensions from the ventricular walls which attach to chordae tendineae to help hold valve cusps in place.

Front 3

Auricles

Back 3

External “earlike” structures which increase the volumes of the atria. These landmarks indicate top and sides of heart.

Front 4

Right Atrium

Back 4

The right atrium is a weak pump that fills the right ventricle. It fills via the superior and inferior vena cavae, and it ejects past the tricuspid valve into the right ventricle below it for delivery to the lungs and re oxygenation of the bluish blood it carries

Front 5

Left Atrium

Back 5

The left atrium is a stronger pump that fills the left ventricle. It fills via the pulmonary veins coming from the lungs, and ejects past the mitral valve into the left ventricle below it for delivery of the bright red, freshly oxygenated blood it contains to the remainder of the body

Front 6

Right Ventricle

Back 6

the right ventricle pumps blood into the pulmonary circulation to/for the lungs. Right ventricle has thinner walls than left

Front 7

Left Ventricle

Back 7

left ventricle pumps blood into the systemic circulation through the aorta (systemic circulation) Thicker walls than the right.

Front 8

Pulmonary Trunk

Back 8

the pulmonary trunk is the "pipe" that your blood goes through to get from the right side of the heart to the lungs to get oxygenated

Front 9

Ascending Aorta

Back 9

The aorta distributes oxygenated blood to all parts of the body through the systemic circulation. is the largest artery in the human body, originating from the left ventricle of the heart and extending down to the abdomen,

Front 10

Descending Aorta

Back 10

The descending aorta is the part of the aorta beginning at the aortic arch that runs down through the chest and abdomen. The descending aorta is divided into two portions, the thoracic and abdominal, in correspondence with the two great cavities of the trunk in which it is situated. Within the abdomen, the descending aorta branches into the two common iliac arteries which serve the pelvis and eventually legs

Front 11

Right Coronary Artery

Back 11

The right coronary artery is the major artery that supplies blood to the upper and lower chambers on the right side of the heart. There is also a left coronary artery.

Front 12

The Great Cardiac Vein

Back 12

It drains blood from the left atrium to the left lung.The great and middle cardiac vein drains blood to the coronary sinus. The coronary sinus also receives blood from left marginal and left posterior veins. It then open and carries deoxgenated blood into the right atrium.

Front 13

Inferior Vena Cava

Back 13

The inferior vena cava (or IVC), also known as the posterior vena cava,[1] is the large vein that carries de-oxygenated blood from the lower half of the body into the right atrium of the heart.

Front 14

Superior Vena Cava

Back 14

The superior vena cava in the upper chest near the heart. It’s purpose is to carry deoxygenated blood to the right atrium of the heart, from the upper right portion of the body.
