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 ( 4 + 1 ⁄ 2 inches) in ...
The unipapillary kidney with a single renal pyramid is the simplest type of kidney in mammals, from which the more structurally complex kidneys are believed to have evolved. [ 17 ] [ 6 ] [ 18 ] Differences in kidney structure are the result of adaptations during evolution to variations in body mass and habitats (in particular, aridity ) between ...
This illustration demonstrates the normal kidney physiology, including the Proximal Convoluted Tubule (PCT), Loop of Henle, and Distal Convoluted Tubule (DCT). It also includes illustrations showing where some types of diuretics act, and what they do. Renal physiology (Latin renes, "kidneys") is the study of the physiology of the kidney.
The thoracic cavity (or chest cavity) is the chamber of the body of vertebrates that is protected by the thoracic wall (rib cage and associated skin, muscle, and fascia). The central compartment of the thoracic cavity is the mediastinum .
Image credits: cat_prophecy #10. When you get a kidney transplant they don’t take out your original kidneys, so you have 3 kidneys after a transplant. Also, they transplant the new kidney into ...
Unlike mammals, the kidneys of reptiles do not have a clear distinction between cortex and medulla. [43] The kidneys lack the loop of Henle, have fewer nephrons (from about 3,000 to 30,000), and cannot produce hypertonic urine. [3] [21] Nitrogenous waste products excreted by the kidneys may include uric acid, urea and ammonia. [55]
Reasons why we have chest pain on the left Since the heart shares space with other organs , tissues, and nerves, chest pain on the left side could be from a number of other things.
In other words, the word refers to the area of the ventral trunk that is located below the costal cartilages. [4] The word once referred only to the soft portion of the abdomen between the rib cage and the navel (the region once believed to be the seat of hypochondriasis ), but it is not used that way in modern anatomy's schemes for the regions ...
