Which of the choices below is the salt level-monitoring part of the nephron?

The macula densa cells in the distal convoluted tubule are the salt level-monitoring part of the nephron. They detect changes in sodium chloride content of the filtrate passing through the tubule and help regulate the release of renin from the juxtaglomerular cells.


Which cells of the kidney are chemoreceptors that respond to changes in solute content of the filtrate?

The macula densa cells located in the distal convoluted tubule of the kidney are chemoreceptors that respond to changes in solute content of the filtrate. These cells are sensitive to the concentration of sodium and chloride ions in the filtrate, signaling the juxtaglomerular cells to regulate blood pressure and filtration rate accordingly.


The cells of the distal convoluted tubule which monitor changes in urine volume and osmolarity are called what?

The cells in the distal convoluted tubule that monitor changes in urine volume and osmolarity are known as macula densa cells. They are sensitive to the concentration of sodium chloride in the filtrate passing through the tubule and help regulate blood pressure and fluid balance in the body.


Which is the salt level-monitoring part of the nephron?

The macula densa in the distal convoluted tubule of the nephron monitors the salt (sodium and chloride) levels in the filtrate. It plays a role in regulating the release of renin from the juxtaglomerular cells in response to changes in salt concentration, helping to maintain blood pressure and fluid balance in the body.

The Macula Densa cells respond to what?

The Macula Densa cells in the kidney respond mainly to changes in the sodium chloride (NaCl) concentration in the tubular fluid. They help regulate the body's blood pressure and fluid balance by sensing NaCl levels and signaling for adjustments in kidney function.

To what special feature does macula densa refer?

In the kidney, the macula densa is an area of closely packed specialized cells lining the wall of the distal tubule at the point of return of the nephron to the vascular pole of its parent glomerulus glomerular vascular pole. The cells of the macula densa are sensitive to the ionic content and water volume of the fluid in the tubule. If low water volume is detected by these cells, they will produce molecular signals that promote renin secretion by other cells of the juxtaglomerular apparatus. The release of renin is an essential component of the renin-angiotensin-aldosterone system (RAAS), which regulates blood pressure and volume. http://en.wikipedia.org/wiki/Macula_densa

What is the stimulus for renin?

Renin can be upregulated in two ways: Macula densa cells in the early distal tubule of the nephron communicates with the juxtaglomerular cells of the afferent arteriole in the kidney. When the macula densa cells detect low levels of sodium, it will communicate that to the juxtaglomerular cells and in turn that will stimulate the production of renin. This is the glomerular tubular feedback system. The second way it can be stimulated is by the somatic nervous system directly. When the baroreceptors detect a drop in pressure they will stimulate your SNS and inhibit your PNS. This has several cardiovascular effects in addition to stimulating renal nerves that will upregulate more renin from the juxtaglomerular cells.


Macula densa feedback (tubuloglomerular feedback) decrease or increase?

The macula densa is involved in tubuloglomerular feedback to help regulate glomerular filtration rate. An increase in NaCl concentration at the macula densa leads to vasoconstriction of the afferent arteriole, decreasing glomerular filtration rate. Conversely, a decrease in NaCl concentration leads to vasodilation of the afferent arteriole, increasing glomerular filtration rate.

What hormone promotes the reabsorbtion of sodium and potassium ions by the kidney?

When the macula densa in the distal tubules of the kidney sense a decrease in fluid volume, the renin-aldosterone system is activated. Aldosterone is the hormone responsible for sodium retention, causing water to be conserved.
