The glomerular basement membrane of the kidney is the basal lamina layer of the glomerulus.The glomerular endothelial cells, the glomerular basement membrane, and the filtration slits between the podocytes perform the filtration function of the glomerulus, separating the blood in the capillaries from the filtrate that forms in Bowman's capsule. [1]
The glomerulus receives its blood supply from an afferent arteriole of the renal arterial circulation. Unlike most capillary beds, the glomerular capillaries exit into efferent arterioles rather than venules. The resistance of the efferent arterioles causes sufficient hydrostatic pressure within the glomerulus to provide the force for ...
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 diaphragms. Mesangial cells are modified smooth muscle cells that lie between the capillaries.
A heart attack, or myocardial infarction, occurs when blood flow to the heart is suddenly blocked. This medical emergency is often the result of coronary artery disease. ... The causes of heart ...
This can cause an increase of fluid pressure within the glomeruli, thus causing their hypertrophy, or breakdown. [10] Amyloidosis: This disease causes the buildup abnormal proteins called amyloid fibrils. Depositions of amyloid fibrils in the kidneys will eventually lead it to the primary filtration unit, the glomerulus, and cause blockages.
Heart disease is a leading killer around the world and the top cause of death in the United States. It killed an estimated 17.9 million people in 2019, representing 32% of all deaths globally ...
The most common cause of heart attack is coronary artery disease (CAD), which happens when plaque builds up in the arteries that supply blood to the heart. It is possible to have COVID-19 and ...
This process is the myocardial infarction or "heart attack". [73] If the heart attack is not fatal, fibrous organization of the clot within the lumen ensues, covering the rupture but also producing stenosis or closure of the lumen, or over time and after repeated ruptures, resulting in a persistent, usually localized stenosis or blockage of the ...
