glomerulus

…kidney, the tubules and the glomerulus, are associated with two groups of bone diseases: the former with a low level of phosphate in the blood (hypophosphatemia) and the latter with renal osteodystrophy (see below), both characterized by rickets and osteomalacia. In addition, kidney transplantation is associated with overactivity of the…

…kidney that produce urine: the glomeruli and the nephrons. The glomeruli are small round clusters of capillaries (microscopic blood vessels) that are surrounded by a double-walled capsule, called Bowman’s capsule. Bowman’s capsule in turn connects with a long tubule. The capsule and attached tubule are known as a nephron. In…

…on the vessels of the glomerular tuft. The suffix “-itis” suggests an inflammatory lesion, and glomerulonephritis is indeed associated with infection, in the limited sense that it may begin soon after a streptococcal infection and may be aggravated in its later course by infections of various kinds. Nevertheless, there is…

…pumps the blood into the glomerulus, an organ formed from an in-tucking of the hind wall of the proboscis cavity. From the glomerulus the blood is collected into two channels that lead backward to the ventral longitudinal vessel. This vessel supplies the body wall and gut with a network of…

…millions of small units called glomeruli. The glomeruli are contained within the nephrons, the so-called functional units of the kidneys. The nephrons can be divided into distinct regions in which the absorptive processes are different: the proximal tubule, leading directly from the glomerulus; the loop of Henle; the distal tubule,…

…of capillary blood vessels, the glomerulus. Bowman’s capsule is continuous with the proximal convoluted tubule, which also lies in the cortex. Following the proximal convoluted tubule is the loop of Henle, which descends into the medulla and then runs straight up again to the cortex where it continues as the…

…that filter blood from the glomerulus and tubules whose cells reabsorb water and nutrients and secrete nitrogenous wastes. Glomeruli are absent in some marine fish; urine then forms solely in the tubules, a process that conserves water. The tubules empty into a long tube, the Wolffian duct, a remnant of…

…of microscopic blood vessels—capillaries—called the glomerulus. The capsule and glomerulus together constitute the renal corpuscle. Blood flows into and away from the glomerulus through tiny arteries called arterioles, which reach and leave the glomerulus through the open end of the capsule. In the renal corpuscle, fluid filters out of the…
