Step by step
Solved in 2 steps
- Secretion of the hormone ADH may decrease or stop if the pituitarys posterior lobe is damaged, as by a blow to the head. This is one cause of diabetes insipidus. People with this form of diabetes excrete so much dilute urine that they may become seriously dehydrated. Where are the target cells of ADH?Renin is an important proteolytic enzyme produced by the kidney, involved in the control of salt/water balance in the body. Explain the source of renin, how it is secreted and how it acts to ultimately influence plasma volume. A separate hormonal system exists for directly controlling kidney water reabsorption. Explain how this hormone is released and how it exerts its renal effects.are both statements correct? In the absence of ADH, the kidneys produce dilute urine; renal tubules absorb more solutes than water. In the presence of ADH, the kidneys produce concentrated urine; large amounts of water are reabsorbed from the tubular fluid into interstitial fluid, increasing solute concentration of the urine
- Explain how the capacity (function) of the sodium potassium pumps found in the ascending loop of Henle enable the establishment of the medullary concentration gradient..Identify the tubular transport mechanisms that are hormonally regulated.describe feedback mechanisms that regulate water intake and hormonal controls of water output in urine.
- Describe the reabsorption of water, and compare how it is regulated by the actions of aldosterone and antidiuretic hormone.How would blood pressure be affected if a person suffered from hypoaldosteronism (insufficient aldosterone secretion)? Wouldblood K+ levels also be affected? If so, how?Diagram control of aldosterone secretion.
- Contrast the control of calcium and phosphate ion excretion by PTH?Draw a graph showing the quantitative relation between the amount of glucose in the plasma vs. the amount of glucose absorbed in the kidney. Thinking about the graph just above, what factor(s)s do you think might be affected in an individual who has diabetes, and why?List the sequence of events leading from increased renin secretionto increased aldosterone secretion?
