Heart Structure
Right Ventricle
The right ventricle is the chamber within the heart that is responsible for pumping oxygen-depleted blood to the lungs.
Superior Vena Cava
The superior vena cava (SVC) is the superior of the two venae cavae, the great venous trunks that return deoxygenated blood from the systemic circulation to the right atrium of the heart. It is a large-diameter (24 mm), yet short, vein that receives venous return from the upper half of the body, above the diaphragm.
Pulmonary Valve
a semilunar valve between the pulmonary artery and the right ventricle of the heart that prevents the blood from flowing back into the right ventricle. ... pulmonary valve
pulmonary trunk
It plays a vital role in pulmonary circulation by conducting deoxygenated blood from the heart to the lungs. The pulmonary trunk and its branches, the pulmonary arteries, are the only arteries in the human body that carry deoxygenated blood instead of oxygenated blood.
Tricuspid Valve
One of the four heart valves, the first one that blood encounters as it enters the heart. The tricuspid valve stands between the right atrium and the right ventricle, and it allows blood to flow only from the atrium into the ventricle.
pulmonary arteries (l/r)
Pulmonary artery definition, an artery conveying venous blood from the right ventricle of the heart to the lungs.
Pulmonary Veins (l/r)
Pulmonary vein: One of four vessels that carry aerated blood from the lungs to the left atrium of the heart.
aortic valve
The aortic valve is a valve in the human heart between the left ventricle and the aorta. It is one of the two semilunar valves of the heart, the other being the pulmonary valve. The heart has four valves and the other two are the mitral and the tricuspid valves.
Right Atrium
The atrium (plural: atria) is a blood collection chamber of the heart. It was previously called the auricle, and that term is still used to describe this chamber in, for example, the Mollusca, but in humans that name is now used for an appendage of the atrium.
Right auricle
The atrium (plural: atria) is a blood collection chamber of the heart. It was previously called the auricle, and that term is still used to describe this chamber in, for example, the Mollusca, but in humans that name is now used for an appendage of the atrium. Visually, they look like wrinkled pouch-like structures. Their purpose is to increase the capacity of the atrium, and so also increase the volume of blood that it is able to contain.
left ventricle
left ventricle n. The chamber on the left side of the heart that receives the arterial blood from the left atrium and contracts to force it into the aorta. ... The great artery that arises from the left ventricle of the heart.
Inferior Vena Cava
The inferior vena cava (or IVC) (Latin: vena, "vein", cavus, "hollow") is a large vein that carries deoxygenated blood from the lower and middle body into the right atrium of the heart. It is formed by the joining of the right and the left common iliac veins, usually at the level of the fifth lumbar vertebra.
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.
left auricle
The left auricle, also known as the left atrial appendage (LAA), is actually a small, muscular pouch at the upper corner of the left atrium. It collects oxygenated blood as it leaves the lungs and moves the blood into the left ventricle.
aorta
the aorta is the largest artery in the body. The aorta begins at the top of the left ventricle, the heart's muscular pumping chamber. The heart pumps blood from the left ventricle into the aorta through the aortic valve.
bicuspid (mitral valve)
A valve of the heart, composed of two triangular flaps, that is located between the left atrium and left ventricle and regulates blood flow between these chambers. Also called bicuspid valve, left atrioventricular valve. mitral valve in Science.
