What is juxtaglomerular apparatus?
What is juxtaglomerular 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 is juxtaglomerular apparatus Class 11?
Often known as the juxtaglomerular complex, the juxtaglomerular apparatus is a system in the kidney that controls the activity of each nephron, the functional unit of the kidney. A specialised structure formed by the distal transformed tubule and the glomerular afferent arteriole is the juxtaglomerular apparatus.
What is the juxtaglomerular apparatus made of?
The juxtaglomerular apparatus, located in the glomerular hilum, consists of a vascular component (afferent and efferent arterioles and extraglomerular mesangium) and a tubular component (macula densa).
Where can you find juxtaglomerular apparatus?
The juxtaglomerular apparatus is part of the kidney nephron, next to the glomerulus. It is found between afferent arteriole and the distal convoluted tubule of the same nephron. This location is critical to its function in regulating renal blood flow and glomerular filtration rate.
What is JGA explain?
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 the full form of GFR?
Glomerular filtration rate (GFR) is a test used to check how well the kidneys are working.
What are the functions of juxtaglomerular cells?
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. It consists of an epithelium-lined lumen and a smooth muscle layer.
How does JGA regulate 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.
Where is the Juxtaglomerular apparatus located quizlet?
Where is the Juxtaglomerular Apparatus located? In the distal tubule, specifically the region that passes between the afferent & efferent arterioles.
How does the juxtaglomerular apparatus (JGA) work?
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. It consists of an epithelium-lined lumen and a smooth muscle layer.
What does Juxtaglomerular cell mean?
The juxtaglomerular cells (JG cells, or 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.
What is the juxtaglomerular complex?
The juxtaglomerular apparatus (also known as the juxtaglomerular complex) is a structure in the kidney that regulates the function of each nephron, the functional units of the kidney. The juxtaglomerular apparatus is named because it is next to (juxta-) the Glomerulus .
