Question
1. If the hypothalamic osmoreceptors detect that you have too much salt per volume of water (i.e., you are hypertonic), kidneys to reabsorb more water. This may result in an unintended and hazardous increase in your is released which causes the 2. What are key differences in the descending loop of Henle compared with the ascending loop of benle? 3. Which renal processes are selective and which are non-selective? Renal processes: Glomerular filtration Tubular reabsorption Tubular secretion 4. Aldosterone causes the distal and collecting tubules to reabsorb K+. True or False Explain why? 5. Which type of immune cells produce antibodies which mark invaders for destruction? 6. What is one cause of metabolic acidosis, what chemical change occurs in this situation, and how do the lungs respond to this situation? 7. When blood pH is too high, which substance would likely be excreted in larger quantities in the a) Ammonia b) Urea c) Hydrogen ions d) Bicarbonate ionsExplanation / Answer
1 ) vasopressin hormone , urine
2 ) The descending limb of henley has low permeability to ions and urea, while being highly permeable to water. The loop has a sharp bend in the renal medulla going from descending to ascending thin limb.
The thin ascending limb of henley is impermeable to water, but it is permeable to ions.
3 ) glomerular filteration comes under nonselective renal process
tubular reabsorption and tubular secreation comes under selective renal processes
4 ) FALSE becuse aldosterone do reabsorption of sodium and excretion of potassium of the kidney, thereby indirectly influencing water retention or loss, blood pressure and blood volume.
5 ) B cells produce antibodies which will destroy the forien bodies
6 ) the Metabolic acidosis and alkalosis are due to a problem with the kidneys. Each of these conditions is caused by an underlying disease or disorder. Treatment depends on the cause.but the Respiratory acidosis and alkalosis are due to a problem with the lungs.
7 ) ammonia is going to eliminate large quantities in unine when PH increases
