Brachiocephalic Trunk

The brachiocephalic artery (or brachiocephalic trunk or innominate artery) is an artery of the mediastinum that supplies blood to the right arm and the head and neck;

Left Common Carotid Artery

This is an artery located in the front of the neck, through which blood from the heart goes to the brain. Together, these arteries provide the principal blood supply to the head and neck. The left common carotid artery arises directly from the aorta;

Left Sublavian Vein

The subclavian vein is a paired large vein, one on either side of the body. Their diameter is approximately that of the smallest finger;

Superior Vena Cava

This is a paired large vein, one on either side of the body. Their diameter is approximately that of the smallest finger;

Left Semilunar Cusp

One of the three semilunar segments serving as the three cusps of a valve preventing regurgitation at the beginning of the aorta: a similar valve guards the entrance of the pulmonary trunk, the segments are named, respectively, anterior, right and left in the pulmona ry valve, and posterior, right, and left in the aortic valve;

Posterior Semilunar Cusp

Of the three semilunar cusps of the aortic valve, the one that lies posteriorly in the fetal heart and in the right posterior position in the adult heart, it does not overlie the origin of either coronary artery;

Right Semilunar Cusp

Chordae Tenddineae

Thread-like bands of fibrous tissue which attach on one end to the edges of the tricuspid and mitral valves of the heart and on the other end to the papillary muscles, small muscles within the heart that serve to anchor the valves;

Posterior Papillary Muscle

These 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);

Left Brachiocephalic Vein

The left and right brachiocephalic veins (or innominate veins) in the upper chest are formed by the union of each corresponding internal jugular vein and subclavian vein. This is at the level of the sternoclavicular joint.[1] The left brachiocephalic vein is usually longer than the right. These veins merge to form the superior vena cava, a great vessel, posterior to the junction of the first costal cartilage with the manubrium sternum. The brachiocephalic veins are the major veins returning blood to the superior vena cava;

Right Brachiocephalic Vein

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 pulmonaryarteries to reach the corresponding lungs;

Right Auricle

The right auricle of the heart also called the right atrial appendage (RAA) is attached to the heart’s right atrium. It’s a small, cone-shaped pouch which comes out from the upper and front part of the atrium and overlaps the root of the aorta. The RAA is very muscular, and is lined with small muscles on its surface. It collects deoxygenated blood from the bloodstream and moves it into the heart’s right ventricle;

Right Pulmonary Artery

This is an artery in the pulmonary circulation that carries deoxygenated blood from the right side of the heart to the lungs. The largest pulmonary artery is the main pulmonary artery or pulmonary trunk from the heart, and the smallest ones are the arterioles which lead to the capillaries that surround the pulmonary alveoli;

Right Pulmonary Veins

Pulmonary veins are responsible for carrying oxygenated blood from the lungs back to the left atrium of the heart. Humans have four pulmonary veins in total, two from each lung. There are two right pulmonary veins, known as the right superior and right inferior veins;

Foramen Ovale 1

This is an opening in the septum between the two atria of the heart that is normally present only in the fetus 2: an oval opening in the greater wing of the sphenoid for passage of the mandibular nerve;

Inferior Vena Cava

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);
