The heart is located on the right side of the thorax, the stomach and spleen on the right side of the abdomen and the liver and gall bladder on the left side. The heart's normal right atrium occurs on the left, and the left atrium is on the right. The lung anatomy is reversed and the left lung has three lobes while the right lung has two lobes.
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 ...
In a rare congenital disorder (dextrocardia) the heart is offset to the right side and is felt to be on the left because the left heart is stronger and larger, since it pumps to all body parts. Because the heart is between the lungs, the left lung is smaller than the right lung and has a cardiac notch in its border to accommodate the heart. [8]
Neither levocardia nor dextrocardia is indicative of the orientation of the visceral organs, which can be in situs solitus, where the remainder of the organs are on normal side as well; or situs inversus, in which the viscera (stomach, liver, intestines, lungs, etc.) are on the opposite side as normal. The latter condition may or may not be ...
The opposite is true for the term "posteroanterior," while side-to-side projections are known as either "lateromedial" (from the outside of the left or right side of the body toward the inside) or "mediolateral"(from the inside of that side of the body toward the outside.
Gross anatomy (also called topographical anatomy, regional anatomy, or anthropotomy) is the study of anatomical structures that can be seen by unaided vision. Microscopic anatomy is the study of minute anatomical structures assisted with microscopes , and includes histology (the study of the organization of tissues), and cytology (the study of ...
When one of the astronauts dies, x-rays from his post-mortem exam reveal that his internal organs are located on the wrong side of his body. In The Ink Black Heart of the Cormoran Strike series, an online troll named Anomie attacks the co-creators of a cartoon of the same title as the novel, Edie Lewell and Josh Blay. He kills Edie Ledwell, but ...
For example, the shoulders are lateral to the heart, and the umbilicus is medial to the hips. The medial side of the left knee is the side toward the opposite knee. Radial and ulnar, which describe only structures at or distal to the elbow and may be used interchangeably with medial and lateral in that particular area because they are less ...
