What is the function of Juxtaglomerular?

The juxtaglomerular apparatus functions to maintain blood pressure and to act as a quality control mechanism to ensure proper glomerular flow rate and efficient sodium reabsorption. The urethra extends from the bladder to the surface of the body.

What is secreted by Juxtaglomerular?

The juxtaglomerular cells secrete renin, and as specialised smooth muscle cells surrounding the afferent arteriole also have the capacity to affect the perfusion of the glomerulus.

What are the 3 components of the Juxtaglomerular?

The three cellular components of the apparatus are the macula densa, extraglomerular mesangial cells, and juxtaglomerular cells (also known as granular cells)[WP].

What is Juxtaglomerular?

The juxtaglomerular apparatus is a specialized structure formed by the distal convoluted tubule and the glomerular afferent arteriole. It is located near the vascular pole of the glomerulus and its main function is to regulate blood pressure and the filtration rate of the glomerulus.

Why are doctors interested in the glomerular filtration rate GFR of a patient?

The GFR test measures how well your kidneys are filtering the blood. Your doctor may order this test if there are signs that your kidneys are not working well. It may also be done to see how far kidney disease has progressed. The GFR test is recommended for people with chronic kidney disease.

Which hormone is secreted by juxtaglomerular cells?

Renin
Renin is a hormone secreted by the juxtaglomerular cells of the kidney; it interacts with a plasma protein substrate to produce a decapeptide prohormone angiotensin I.

Where are the Juxtaglomerular cells?

kidney
Juxtaglomerular cells (JG cells), also known as granular cells are cells in the kidney that synthesize, store, and secrete the enzyme renin. They are specialized smooth muscle cells mainly in the walls of the afferent arterioles (and some in the efferent arterioles) that deliver blood to the glomerulus.

Where are the Juxtaglomerular located?

glomerulus
The juxtaglomerular apparatus is a specialized structure formed by the distal convoluted tubule and the glomerular afferent arteriole. It is located near the vascular pole of the glomerulus and its main function is to regulate blood pressure and the filtration rate of the glomerulus.
