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), composed of intraglomerular mesangial cells.

Plural glomeruli (glō-mĕr′yə-lī′)

: a small convoluted or intertwined mass especially : a tuft of capillaries at the point of origin of each vertebrate nephron that passes a protein-free filtrate to the surrounding Bowman’s capsule.

As nouns the difference between glomeruli and glomerulus is that glomeruli is (glomerulus) while glomerulus is (anatomy) a small intertwined group of capillaries within nephrons of the kidney that filter the blood to make urine.

Glomerulus is the diminutive of the Latin glomus, meaning “ball of yarn”. the filtering unit of the kidney; see Glomerulus (kidney). a structure in the olfactory bulb; see Glomerulus (olfaction).

The glomerulus in the kidney was so named by the Italian anatomist Marcello Malpighi (1628-1694). The structure was once called a malphigian corpuscle. “Glomerulus” is the diminutive of the Latin “glomus” meaning “ball of yarn.” It is literally a “little ball of yarn.” Plural: glomeruli.

The glomerulus is a network of capillaries, located at the beginning of a nephron in the kidney. The glomerulus filters blood and produces the glomerular filtrate. This filtrate contains water, glucose, salts and urea. Large molecules such as protein are too large to fit through the blood capillary walls.

The glomerulus is the site in the nephron where fluid and solutes are filtered out of the blood to form a glomerular filtrate. The proximal and distal tubules, the loop of Henle, and the collecting ducts are sites for the reabsorption of water and ions.

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.

Each nephron in your kidneys has a microscopic filter, called a glomerulus that is constantly filtering your blood. Blood that is about to be filtered enters a glomerulus, which is a tuft of blood capillaries (the smallest of blood vessels).

The mature glomerulus contains four cell types: Parietal epithelial cells that form Bowman’s capsule, podocytes that cover the outermost layer of the glomerular filtration barrier, glycocalyx-coated fenestrated endothelial cells that are in direct contact with blood, and mesangial cells that sit between the capillary …

Bowman’s capsule is a part of the nephron that forms a cup-like sack surrounding the glomerulus. Bowman’s capsule encloses a space called “Bowman’s space,” which represents the beginning of the urinary space and is contiguous with the proximal convoluted tubule of the nephron.

Bowman’s capsule is named after Sir William Bowman (1816–1892), a British surgeon and anatomist.

Bowman’s capsule is a membranous double-walled capsule which surrounds the glomerulus of the nephron. The glomerulus is a tuft of capillaries in the nephron. Bowman’s capsule collects blood, filtrate it and sends it to renal tubule for further processing in order to form urine. Glomerulus filters the blood plasma.

The parietal epithelial cells (parietal podocytes) lining Bowman’s capsule are flat and squamoid cells, which express different markers than visceral podocytes. While these cells uniformly express pax-2, there is patchy expression of the visceral podocyte markers WT-1 and podocalyxin.

uriniferous tubules

The papilla, or inner medulla, lies in the center of the adult kidney protruding into the pelvis. The collecting ducts pass through the papilla providing a conduit for the urinary filtrate to reach the ureter. At birth, the papilla is very short and contained within the pelvis.

Step 5: Stay Healthy

1. 6 Things People with Kidney Disease Should Do: Lower high blood pressure. Manage blood sugar levels. Reduce salt intake. Avoid NSAIDs, a type of painkiller. Moderate protein consumption.
2. 9 Things Everyone Should Do: Exercise regularly. Control weight. Follow a balanced diet. Quit smoking.

Based on autopsy specimens from individuals representing various ethnic groups, a large variation in nephron number exists in the “normal” adult human kidney, such that each kidney contains anywhere from 200,000 to over 1.8 million nephrons.

Pyonephrosis—pus in the renal pelvis—results from urinary tract obstruction in the presence of pyelonephritis.

Acute pyelonephritis is a sudden and severe kidney infection. It causes the kidneys to swell and may permanently damage them. Pyelonephritis can be life-threatening.

The diagnosis of pyonephrosis is suspected when the clinical symptoms of fever and flank pain are combined with the radiologic evidence of obstruction to the urinary tract. Sonography gives a prompt diagnosis of hydronephrosis, and needle puncture of the kidney yields pus and establishes the presence of pyonephrosis.

Pyonephrosis is characterized by accumulation of purulent debris and sediment in the renal pelvis and urinary collecting system. Children with pyonephrosis have symptoms similar to those of acute pyelonephritis, but frequently symptoms are more severe or persistent, or there are additional signs of hydronephrosis.

Patients with pyonephrosis may present with a variety of clinical symptoms ranging from asymptomatic bacteruria (15%) to frank sepsis. The clinician should have a high index of suspicion when examining a patient presenting with fever, flank pain, urinary tract infection, and obstruction or hydronephrosis.

What is Nephrolithiasis (Kidney Stones; Renal Calculi; Urinary Stones) Nephrolithiasis (kidney stones) is a disease affecting the urinary tract. Kidney stones are small deposits that build up in the kidneys, made of calcium, phosphate and other components of foods. They are a common cause of blood in urine.

Your doctor can determine whether a juice may cause side effects for you or your baby.

• Water. When passing a stone, upping your water intake can help speed up the process.
• Lemon juice.
• Basil juice.
• Apple cider vinegar.
• Celery juice.
• Pomegranate juice.
• Kidney bean broth.
• Dandelion root juice.

Kidney Stone Treatment Options

• Non-invasive extracorporeal shock wave lithotripsy (ESWL). ESWL involves the use of sound waves to crush the kidney stone into smaller pieces so they can more easily pass into the bladder.
• Percutaneous nephrolithotomy (PCNL).
• Ureteroscopy (URS).
• Pyelolithotomy.
