Renal corpuscle showing glomerulus and glomerular capillaries Figure 2: (a) Diagram of the juxtaglomerular apparatus: it has specialized cells working as a unit which monitor the sodiujuxtaglomerular apparatus: it has three types of specm content of the fluid in the distal convoluted tubule (not labelled - it is the tubule on the left) and adjust the glomerular filtration rate and the rate of ...
Damage to skeletal muscle may take various forms. Crush and other physical injuries cause damage to muscle cells directly or interfere with blood supply, while non-physical causes interfere with muscle cell metabolism. When damaged, muscle tissue rapidly fills with fluid from the bloodstream, including sodium ions.
Causes of edema that are generalized to the whole body can cause edema in multiple organs and peripherally. For example, severe heart failure can cause pulmonary edema, pleural effusions, ascites and peripheral edema. Such severe systemic edema is called anasarca. In rare cases, a parvovirus B19 infection may cause generalized edemas. [9]
The renal corpuscle is composed of two structures, the glomerulus and the Bowman's capsule. [3] The glomerulus is a small tuft of capillaries containing two cell types. . Endothelial cells, which have large fenestrae, are not covered by dia
In the physiology of the kidney, tubuloglomerular feedback (TGF) is a feedback system inside the kidneys.Within each nephron, information from the renal tubules (a downstream area of the tubular fluid) is signaled to the glomerulus (an upstream area).
Low pressure in the arteries, causes the opposite reflex of constriction of the arterioles, and a speeding up of the heart rate (called tachycardia). If the drop in blood pressure is very rapid or excessive, the medulla oblongata stimulates the adrenal medulla , via "preganglionic" sympathetic nerves , to secrete epinephrine (adrenaline) into ...
Failure of kidneys to remove excess fluid may cause: Swelling of the hands, legs, ankles, feet, or face; Shortness of breath due to extra fluid on the lungs (may also be caused by anemia) Polycystic kidney disease, which causes large, fluid-filled cysts on the kidneys and sometimes the liver, can cause: Pain in the back or side
Proper function of the kidney requires that it receives and adequately filters blood. This is performed at the microscopic level by many hundreds of thousands of filtration units called renal corpuscles, each of which is composed of a glomerulus and a Bowman's capsule.
