What is JGA in nephron?

juxtaglomerular apparatus (JGA) A region of tissue found in each nephron in the kidney that is important is regulating blood pressure and body fluid and electrolytes. The JGA also includes chemoreceptor cells of the adjacent region of the distal tubule, which form a tightly packed array called the macula densa.

What is JGA physiology?

The juxtaglomerular apparatus (JGA) is a specialized contact region between the glomerulus and the cortical thick ascending limb that plays an active role in the maintenance of ion homeostasis and control of blood pressure.

Where is JGA located?

the glomerulus
The JGA is located at the vascular pole of the glomerulus, where a portion of the distal nephron comes into contact with its parent glomerulus.

What is JGA apparatus?

The juxtaglomerular apparatus is the location of renin-secreting cells and the macula densa and lies at the junction between the loop of Henle and the distal nephron at which the tubule comes in close proximity to the afferent arteriole.16.

What comprises the JGA apparatus?

The juxtaglomerular apparatus consists of the juxtaglomerular cells of the afferent glomerular arteriole, the efferent glomerular arteriole, the extraglomerular mesangial cells, and that small portion of the distal tubule known as the macula densa that is located beside the renal glomerulus.

How JGA is regulating the kidney function?

Regulation involving Juxtaglomerular Apparatus: In kidneys, the JGA acts as a Multi Hormonal renin angiotensin aldosterone system (RAAS). When the glomerular blood flow decreases JG cells activates and releases renin. Renin converts angiotensin in blood to angiotensin 1 and further to angiotensin 2.

What is the full form of PCT in bio?

Full form of PCT is proximal convulated tubule. PCT is a part of nephron, the structural and functional unit of kidneys.

How does JGA regulate GFR?

Additional Information: The functions of the cells of JGA are as follows: These cells have a contractile property by which they can control the regulation of GFR or glomerular filtration rate by the alteration of the diameter of the blood vessels.

What is the afferent arteriole?

The afferent arteriole is an arteriole that feeds blood into the glomerulus. The afferent arterioles modulate their vascular resistance in response to changes in intraluminal pressure or composition of tubular fluid at the macula densa. In this manner, they control the glomerular filtration.

What does JGA stand for?

This page is about the various possible meanings of the acronym, abbreviation, shorthand or slang term: JGA. James Gregory Associates, Inc. What does JGA mean? Jupiter gravity assist. An amount of thrust added to a spacecraft by flying close to Jupiter.

What is the function of JGA in the kidney?

JGA stand for Juxtaglomerular apparatus (JGA) A region of tissue found in each nephron in the kidney that is important is regulating blood pressure and body fluid and electrolytes.

What is another name for the chemoreceptor cells of the JGA?

The JGA also includes chemoreceptor cells of the adjacent region of the distal tubule, which form a tightly packed array called the macula densa. What are some good ways to improve English grammar and writing abilities for a non-native speaker?
