The target cells of aldosteron are in the distal convulated tubules. Aldosteron there spreads into the cells, makes complexes with the receptors of the nucleus and codes for genes that are responsible for the proteins (e.g. sodium permease) and ferments (citratsintase, carboanhidrase) that are important for the transfer of sodium ions.

What is the primary chemical affected by the renin-angiotensin-aldosterone system?
sodium
What is the name of the cells in the nephron that respond to ADH and aldosterone?
Endothelial
What does Target cell mean?
Presence of target cells may be due to: Breakdown of red blood cells (decreased osmotic fragility) Deficiency of an enzyme called lecithin cholesterol acyl transferase. Abnormalities of hemoglobin, the protein in red blood cells that carry oxygen (hemoglobinopathies).
What are the target cells of erythropoietin?
The target cells for Erythropoietin are red blood cells
If a tumor of the glucocorticoid-secreting cells of the adrenal cortex crowds out the cells that produce aldosterone what is the likely effect on urine composition and volume?
increase urine composition and increace volume
Aldosterone has its effects mainly on the cells of the?
Kidney
What is the primary chemical affected by the renin-angiotensin-aldosterone system?
sodium
What determines what cell a hormone will effect?
The target receptor proteins of cells will cause them to affected by a specific protein. These cells are also called "target" cells. Hormones flow via the bloodstream throughout the entire body, but they only affect their specific "target" cells.
What regulatory chemicals involve or target the kidneys?
Angiotensin, Aldosterone, ADH, and ANP.
What is the name of the cells in the nephron that respond to ADH and aldosterone?
Endothelial
Body cells that react to particular hormone are called?
target cells
Are hormones target molecules or signal molecules?
Hormones affect target cells because target cells have receptors that bind with certain hormones (they're specific). If a cell does not have a receptor then it is not affected by hormones. Target cells (which do have the receptor for a particular hormone) would be affected by the hormone.
What renal-adjusting hormone cannot be stored within the cells where it is synthesized?
aldosterone
What does Target cell mean?
Presence of target cells may be due to: Breakdown of red blood cells (decreased osmotic fragility) Deficiency of an enzyme called lecithin cholesterol acyl transferase. Abnormalities of hemoglobin, the protein in red blood cells that carry oxygen (hemoglobinopathies).

If a tumor of the glucocorticoid-secreting cells of the adrenal cortex crowds out the cells that produce aldosterone what is the likely effect on urine composition and volume?
increase urine composition and increace volume
What is the roleof aldosterone?
Aldosterone will cause Na+ to be absorbed from a filtrate
