HEarT (Top Cut)

Pulmonary Trunk

This 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 pulmonaryarteries to reach the corresponding lungs;

Left Ventricle

This is one of four chambers of the heart. It is located in the bottom left portion of the heart below the left atrium, separated by the mitral valve. The left ventricle is the thickest of the heart’s chambers and is responsible for pumping oxygenated blood to tissues all over the body;

Left AV Valve

The mitral valve, also known as the bicuspid valve or left atrioventricular valve, is a valve with two flaps in the heart, that lies between the left atrium and the left ventricle;

Aorta

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 Valve

This is one of two valves that allow blood to leave the heart via the arteries. It is a one-way valve, meaning that blood cannot flow back into the heart through it. It is located in the right ventricle of the heart. The pulmonic valve opens into the pulmonary artery;

Pulmonary Muscle

The muscles of respiration are those muscles that contribute to inhalation and exhalation, by aiding in the expansion and contraction of the thoracic cavity. The diaphragm and, to a lesser extent, the intercostal muscles drive respiration during quiet breathing;

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;

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;
