What are the two names of nephrons?

Key Points

• Kidneys contain two types of nephrons, each located in different parts of the renal cortex: cortical nephrons and juxtamedullary nephrons.
• A nephron comprises a renal corpuscle, a renal tubule, and the associated capillary network.

What is a glomerulus?

The glomerulus, the filtering unit of the kidney, is a unique bundle of capillaries lined by delicate fenestrated endothelia, a complex mesh of proteins that serve as the glomerular basement membrane and specialized visceral epithelial cells that form the slit diaphragms between interdigitating foot processes.

What is the main function of glomerulus?

The main function of the glomerulus is to filter plasma to produce glomerular filtrate, which passes down the length of the nephron tubule to form urine.

What is the function of a glomerulus?

In the kidney, the glomerulus represents the initial location of the renal filtration of blood. Blood enters the glomerulus through the afferent arteriole at the vascular pole, undergoes filtration in the glomerular capillaries, and exits the glomerulus through the efferent arteriole at the vascular pole.

What is absorbed in the Bowman’s capsule?

Bowman’s capsule encloses a cluster of microscopic blood vessels—capillaries—called the glomerulus, where wastes are filtered from the blood. Waste products are transferred from the blood into the filtrate while nutrients are absorbed from the filtrate into the blood.

What are the 4 steps of urine formation?

There are four basic processes in the formation of urine starting with plasma.

• Filtration.
• Reabsorption.
• Regulated reabsorption, in which hormones control the rate of transport of sodium and water depending on systemic conditions, takes place in the distal tubule and collecting duct.
• Secretion.
• Excretion.

What is the correct order of urine formation?

There are three main steps of urine formation: glomerular filtration, reabsorption, and secretion. These processes ensure that only waste and excess water are removed from the body.

How the urinary system works step by step?

From the kidneys, urine travels down two thin tubes called ureters to the bladder. The ureters are about 8 to 10 inches long. Muscles in the ureter walls constantly tighten and relax to force urine downward away from the kidneys. If urine is allowed to stand still, or back up, a kidney infection can develop.

What is composition of urine?

It consists of water, urea (from amino acid metabolism), inorganic salts, creatinine, ammonia, and pigmented products of blood breakdown, one of which (urochrome) gives urine its typically yellowish colour.

What is the percentage composition of urine for Class 7?

Answer. It contains 95% if water and urea 9.3 g/L, chloride 1.87 g/L, sodium 1.17 g/L, potassium 0.750 g/L, creatinine 0.670 g/L.

What is the percentage composition of urine?

Urine is an aqueous solution of greater than 95% water. Other constituents include urea, chloride, sodium, potassium, creatinine and other dissolved ions, and inorganic and organic compounds. Urea is a non-toxic molecule made of toxic ammonia and carbon dioxide.

What is the pH of urine?

Normal urine pH is slightly acidic, with usual values of 6.0 to 7.5, but the normal range is 4.5 to 8.0.

How do I read my urine test results?

Dipstick test

1. Acidity (pH). The pH level indicates the amount of acid in urine.
2. Concentration. A measure of concentration, or specific gravity, shows how concentrated particles are in your urine.
3. Protein. Low levels of protein in urine are normal.
4. Sugar.
5. Ketones.
6. Bilirubin.
7. Evidence of infection.
8. Blood.
