Where are the great vessels of the heart located? The great vessels of the heart connect to your heart’s chambers. The chart below shows where each vessel connects and the direction of blood flow.
Jan 8, 2024 · The great vessels of the heart function to carry blood to and from the heart as it pumps, located largely within the middle mediastinum. In this article we will consider the structure and anatomical relationships of the aorta, pulmonary arteries and veins, and the superior and inferior vena cavae.

Five great vessels enter and leave the heart: the superior and inferior vena cava, the pulmonary artery, the pulmonary vein, and the aorta. The superior vena cava and inferior vena cava are veins that return deoxygenated blood from circulation in the body and empty it into the right atrium.
Jul 25, 2023 · The large arteries and veins directly connected with the heart are termed the great vessels, consisting of the inferior vena cava, superior vena cava, pulmonary arteries, pulmonary veins, and root of the aorta.

- Heart anatomy. The heart has five surfaces: base (posterior), diaphragmatic (inferior), sternocostal (anterior), and left and right pulmonary surfaces. It also has several margins: right, left, superior, and inferior
- Heart valves. Heart valves separate atria from ventricles, and ventricles from great vessels. The valves incorporate two or three leaflets (cusps) around the atrioventricular orifices and the roots of great vessels.
- Blood flow through the heart. The blood flow through the heart is quite logical. It happens with the heart cycle, which consists of the periodical contraction and relaxation of the atrial and ventricular myocardium (heart muscle tissue).
- Coronary circulation. The heart must also be supplied with oxygenated blood. This is done by the two coronary arteries: left and right. Heart muscles work constantly (thank goodness!)
Sep 1, 2013 · Heart Valves. Blood flows through the heart in one direction: from the atria to the ventricles and out the great arteries leaving the superior aspect of the heart. Four valves enforce the one-way traffic. They open and close in response to differences in blood pressure. Atrioventricular (AV) Valves. There are two atrioventricular (AV) valves ...
Oct 20, 2024 · The great veins, the superior and inferior venae cavae, and the great arteries, the aorta and pulmonary trunk, are attached to the superior surface of the heart, called the base. The base of the heart is located at the level of the third costal cartilage, as seen in Figure \(\PageIndex{1}\).
