Adipose tissue (also known as body fat or simply fat) is a loose connective tissue composed mostly of adipocytes. [ 1 ] [ 2 ] It also contains the stromal vascular fraction ( SVF ) of cells including preadipocytes , fibroblasts , vascular endothelial cells and a variety of immune cells such as adipose tissue macrophages .
The right coronary sulcus begins anteriorly and superiorly on the sternocostal surface of the heart. Its position is marked by the location of the right coronary artery, and small cardiac vein. The right coronary sulcus separates the right atrium and its atrial appendage from the right ventricle inferiorly. The right coronary sulcus then passes ...
[15] [7] It remains to be determined whether these deposits are 'classical' brown adipose tissue or beige/brite fat. [16] [17] Brown fat in humans in the scientific and popular literature refers to two cell populations defined by both anatomical location and cellular morphology.
A typical fat cell is 0.1 um in diameter [2] with some being twice that size, and others half that size. However, these numerical estimates of fat cell size depend largely on the measurement method and the location of the adipose tissue. [2] The fat stored is in a semi-liquid state, and is composed primarily of triglycerides, and cholesteryl ester.
The heart requires a continuous supply of oxygen to function and survive, much like any other tissue or organ of the body. [1] The coronary arteries wrap around the entire heart. The two main branches are the left coronary artery and right coronary artery. The arteries can additionally be categorized based on the area of the heart for which ...
A kind of memory of obesity may be retained by fat tissues even after weight loss, increasing the chance of some people regaining it, a new study suggests. The research, published in the journal ...
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 connective tissue, along with the paranodal cells, insulate the SA node from the rest of the atrium, preventing the electrical activity of the atrial cells from affecting the SA node cells. [2] The SA node cells are smaller and paler than the surrounding atrial cells , with the average cell being around 8 micrometers in diameter and 20-30 ...
