The brachiocephalic artery, brachiocephalic trunk, or innominate artery is an artery of the mediastinum that supplies blood to the right arm, head, and neck. [1] [2] It is the first branch of the aortic arch. [3] Soon after it emerges, the brachiocephalic artery divides into the right common carotid artery and the right subclavian artery. [4]
The heart is a muscular organ situated in the mediastinum.It consists of four chambers, four valves, two main arteries (the coronary arteries), and the conduction system. The left and right sides of the heart have different functions: the right side receives de-oxygenated blood through the superior and inferior venae cavae and pumps blood to the lungs through the pulmonary artery, and the left ...
During the development of the human heart, the right horn and transverse portion of the sinus venosus ultimately become incorporated with and form a part of the adult right atrium. [1] The right sinus horn [ 4 ] of the sinus venosus develops into the sinus venarum ; in the adult right atrium, the portion of right atrium derived from the sinus ...
The right coronary artery supplies oxygenated blood to the right atrium, the right ventricle, and the posterior third and inferior end of the interventricular septum. [2] [5] It may also supply 25% to 35% of the left ventricle (LV). [10] There is significant overlap of supply of the coronary arteries. [2]
The upper part of the heart is located at the level of the third costal cartilage. [8] The lower tip of the heart, the apex, lies to the left of the sternum (8 to 9 cm from the midsternal line) between the junction of the fourth and fifth ribs near their articulation with the costal cartilages. [8]
The Absolute Best Arm To Get Vaccines In, According to Research and Experts Dr. Handel says scientists are still hashing that out, and recent research has produced conflicting results.
Dextrocardia (from Latin dextro ' right hand side ' and Greek kardia ' heart ') is a rare congenital condition in which the apex of the heart is located on the right side of the body, rather than the more typical placement towards the left. [1]
The right and left fibrous rings of heart (annuli fibrosi cordis) surround the atrioventricular and arterial orifices. The right fibrous ring is known as the annulus fibrosus dexter cordis, and the left is known as the annulus fibrosus sinister cordis. [3] The right fibrous trigone is continuous with the central fibrous body.
