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 ...
The heart is a muscular organ found in most animals. This organ pumps blood through the blood vessels of the circulatory system. [ 1 ] The pumped blood carries oxygen and nutrients to the body, while carrying metabolic waste such as carbon dioxide to the lungs. [ 2 ]
The right atrial appendage is a pouch-like extension of the right atrium and is covered by a trabecula network of pectinate muscles. The interatrial septum separates the right atrium from the left atrium; this is marked by a depression in the right atrium – the fossa ovalis. The atria are depolarised by calcium. [6]
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] There are two main types of dextrocardia: dextrocardia of embryonic arrest (also known as isolated ...
The function of the right heart, is to collect de-oxygenated blood, in the right atrium, from the body via the superior vena cava, inferior vena cava and from the coronary sinus and pump it, through the tricuspid valve, via the right ventricle, through the semilunar pulmonary valve and into the pulmonary artery in the pulmonary circulation ...
The circulatory system is a system of organs that includes the heart, blood vessels, and blood which is circulated throughout the entire body of a human or other vertebrate. [ 1 ][ 2 ] It includes the cardiovascular system, or vascular system, that consists of the heart and blood vessels (from Greek kardia meaning heart, and from Latin vascula ...
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.
7100. Anatomical terminology. [edit on Wikidata] A ventricle is one of two large chambers located toward the bottom of the heart that collect and expel blood towards the peripheral beds within the body and lungs. The blood pumped by a ventricle is supplied by an atrium, an adjacent chamber in the upper heart that is smaller than a ventricle.
