Hypertension represents a common and powerful predisposing factor for cardiovascular disease or events and renal failure. Approximately 90% of patients with end-stage renal disease (ESRD) have a history of hypertension. High blood pressure may initiate renal damage and also increase the rate of progression of renal insufficiency. Persistent high blood pressure represents the early trigger mechanism for renal disease.
The final pathway is represented by progressive sclerosis of glomeruli (Vascular part of nephron). A main role is played by transforming growth factor 1 (TGF1), a multifunctional cytokine that regulates cell growth, differentiation, matrix production, blocks matrix degradation, inducing fibrosis in many tissues, including kidney, blood vessels, lung and heart. High circulating levels of TGF1 can mediate renal fibrosis and loss of function.
the cortical nephron is another type of nephron which has shorter loop of henle extended in medulla region. it has no proper function but it works like as ultra filtration etc as juxta medullary nephron perform but juxta medullary has proper function.
The blood pressure in these capillaries is relatively high, so pressure filtration occurs. The blood's plasma and small waste materials and chemicals (the contents of the closet) are pushed out of the blood into the nephron, leaving behind larger proteins, nutrients, and blood cells.
The juxtaglomerular apparatus is a specialized structure found in the kidney that regulates blood pressure and kidney function. It consists of the macula densa, juxtaglomerular cells, and extraglomerular mesangial cells, which work together to control the release of renin and the constriction of blood vessels.
The nephron consists of the glomerulus, proximal convoluted tubule, loop of Henle, distal convoluted tubule, and collecting duct. The glomerulus filters blood to form filtrate, which passes through the tubules for reabsorption of essential substances and secretion of waste products. The loop of Henle plays a crucial role in creating a concentration gradient in the kidney, while the collecting duct helps regulate the body’s water balance by reabsorbing water.
Filtration in the nephron occurs in the glomerulus. Blood pressure forces small molecules like water, ions, and waste products to pass through the filtration membrane into the renal tubule. This initial filtrate is then processed through reabsorption and secretion in different parts of the nephron to form urine.
list the parts of the nephron and describe the function of each part
The nephron is a functional unit of the kidney which filters the blood and maintains the body's internal homeostasis.

Yes
The distal tubule and collecting duct are the parts of the nephron that are under the control of the hormones ADH (antidiuretic hormone) and aldosterone. These hormones regulate water reabsorption and sodium reabsorption, respectively, in these segments of the nephron.

If your blood pressure is too high, as in the case of someone with hypertension, the glomerulus of the nephron can burst rendering that nephron useless. Without a glomerulus, the nephron cannot achieve pressure filtration, which is one of the main functions of the kidney.
nephron, each kidney has atleast 1 million
A diuretic that acts at the distal part of the nephron is usually a thiazide or thiazide-like diuretic, such as hydrochlorothiazide or chlorthalidone. These diuretics work by inhibiting sodium and chloride reabsorption in the distal convoluted tubule of the nephron, leading to increased urine output.
Nephrons have the same function in all kidneys. They allow the excretion of water, sodium and urea to form urine. They serve the function of removing waste chemicals such as metabolites and drugs from the body. Excretion of sodium and water is also important in the nephron as it allows the kidney to control blood pressure and blood volume.
The juxtaglomerular apparatus is located in the kidney, specifically at the point where the afferent arteriole and the distal convoluted tubule come into close contact in the nephron. It plays a key role in regulating blood pressure and kidney function.
The Bowman's Capsule is part of a Nephron, which would be found in the Kidney. It's function is to collect the filtrate from the Glomerulus, passing it on to the Proximal Convoluted Tubules (PCT's); subsequently, to the rest of the Nephron.
