Kidney. In humans, the kidneys are two reddish-brown bean-shaped blood-filtering organs [1] that are a multilobar, multipapillary form of mammalian kidneys, usually without signs of external lobulation. [2] [3] They are located on the left and right in the retroperitoneal space, and in adult humans are about 12 centimetres ( 41⁄2 inches) in ...
Renal physiology ( Latin rēnēs, "kidneys") is the study of the physiology of the kidney. This encompasses all functions of the kidney, including maintenance of acid-base balance; regulation of fluid balance; regulation of sodium, potassium, and other electrolytes; clearance of toxins; absorption of glucose, amino acids, and other small ...
This article contains a list of organs in the human body. It is widely believed that there are 79 organs (this number goes up if you count each bone and muscle as an organ on their own, which is becoming a more common practice [1] [2]); however, there is no universal standard definition of what constitutes an organ, and some tissue groups' status as one is debated. [3]
Excretory system. The excretory system is a passive biological system that removes excess, unnecessary materials from the body fluids of an organism, so as to help maintain internal chemical homeostasis and prevent damage to the body. The dual function of excretory systems is the elimination of the waste products of metabolism and to drain the ...
Anatomical diagram of RAS [ 1] The renin–angiotensin system ( RAS ), or renin–angiotensin–aldosterone system ( RAAS ), is a hormone system that regulates blood pressure, fluid and electrolyte balance, and systemic vascular resistance. [ 2][ 3] When renal blood flow is reduced, juxtaglomerular cells in the kidneys convert the precursor ...
Blood tests are also used to assess kidney function. These include tests that are intended to directly measure the function of the kidneys, as well as tests that assess the function of the kidneys by looking for evidence of problems associated with abnormal function. One of the measures of kidney function is the glomerular filtration rate (GFR).
Body without organs. A schizoanalytical diagram of the social dynamic of the body without organs, from Anti-Oedipus. The body without organs (or BwO; French: corps sans organes or CsO) [1] is a fuzzy concept used in the work of French philosophers Gilles Deleuze and Félix Guattari. The concept describes the unregulated potential of a body ...
Exercise. Staying physically active is important to maintain fluid balance in the body and prevent water retention, the experts note. Exercise can also promote fluid loss through sweating ...
