HEarT (Anterior Cut)

Pulmonary Arteries

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

Superior Venacava

This is a large vein carrying deoxygenated blood into the heart. There are two in humans, the inferior vena cava (carrying blood from the lower body) and the superior vena cava (carrying blood from the head, arms, and upper body);

Right Atrium

The right upper chamber of the heart. The right atrium receives deoxygenated blood from the body through the vena cava and pumps it into the right ventricle which then sends it to the lungs to be oxygenated;

Right Av Valve

The tricuspid valve, or right atrioventricular valve, is on theright dorsal side of the mammalian heart, between the rightatrium and the right ventricle. The function of the valve is to prevent back flow of blood into the right atrium;

Right Ventricle

The right ventricle is the chamber within the heart that is responsible for pumping oxygen-depleted blood to the lungs. The right ventricle is one of the heart’s four chambers. It is located in the lower right portion of the heart below the right atrium and opposite the left ventricle;

Chordae Tenddinae

The chordae tendineae (tendinous chords), colloquially known as the heart strings, are cord-like tendons that connect the papillary muscles to the tricuspid valve and the mitral valve in the heart;

Inferior Venacava

This is a large vein carrying deoxygenated blood into the heart. There are two in humans, the inferior vena cava (carrying blood from the lower body) and the superior vena cava (carrying blood from the head, arms, and upper body);

Aorta

This is the main artery of the body, supplying oxygenated blood to the circulatory system. In humans it passes over the heart from the left ventricle and runs down in front of the backbone;

Pulmonary Veins

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

Pulmonary Trunk

The pulmonary trunk is a major vessel of the human heart that originates from the right ventricle. It branches into the right and left pulmonary arteries, which lead to the lungs. From here, the blood travels through each of the pulmonary arteries to reach the corresponding lungs;

Left Atrium

The left atrium is one of the four chambers of the heart, located on the left posterior side. Its primary roles are to act as a holding chamber for blood returning from the lungs and to act as a pump to transport blood to other areas of the heart;

Papillary Muscle

The papillary muscles are muscles located in the ventricles of the heart. They attach to the cusps of the atrioventricular valves (also known as the mitral and tricuspid valves) via the chordae tendineae and contract to prevent inversion or prolapse of these valves on systole (or ventricular contraction);

Aortic Valve

This is a semilunar valve between the aorta and the left ventricle of the heart that prevents the blood from flowing back into the left ventricle. Examples from the Web for aortic valve;

Left AV Valve

This is a valve which separate the atria from the ventricles, allow blood to flow from the atria to the ventricles, but prevent flow in the opposite direction. The right AV valves is called the tricuspid valve. The left AV valve is called the mitral valve;
