Chronic kidney disease (CKD) is a type of kidney disease in which there is gradual loss of kidney function over a period of months to years. Initially there are generally no symptoms; later, symptoms may include leg swelling, feeling tired, vomiting, loss of appetite, and confusion. Complications include an increased risk of heart disease, high blood pressure, bone disease, and anemia.
The glomerulus (plural glomeruli), is a network of small blood vessels (capillaries) known as a tuft, located at the beginning of a nephron in the kidney. The tuft is structurally supported by the mesangium - the space between the blood vessels - made up of intraglomerular mesangial cells. The blood is filtered across the capillary walls of this tuft through the glomerular filtration barrier, which yields its filtrate of water and soluble substances to a cup-like sac known as Bowman's capsule. The filtrate then enters the renal tubule, of the nephron.
Steak and kidney pie is a savoury pie that is filled principally with a mixture of diced beef, diced kidney (often of beef, lamb, or pork ), fried onion, and brown gravy. Steak and kidney pie is a representative dish of British cuisine.
In the blood supply of the kidney, the straight arterioles of kidney (or vasa recta renis) are a series of straight capillaries in the medulla (Latin: vasa, "vessels"; recta, "straight"). They lie parallel to the loop of Henle.
The reniculate kidney is a multilobed kidney found in marine and aquatic mammals such as pinnipeds (seals, sea lions and walruses ) and cetaceans (dolphins and whales ) but absent in terrestrial mammals except bears. Kidneys of this morphology have increased surface area for removing toxins from the body more efficiently than a non-lobed kidney.
The National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) is part of the United States National Institutes of Health, which in turn is part of the Department of Health and Human Services. NIDDK is approximately the fifth-largest of the 27 NIH institutes. The institute's mission is to support research, training, and communication with the public in the topic areas of "diabetes and other endocrine and metabolic diseases; digestive diseases, nutritional disorders, and obesity; and kidney, urologic, and hematologic diseases". As of 2015, the Director of the institute is Griffin P. Rodgers, who assumed the position on an acting basis in 2006 and on a permanent basis in 2007.
