Question

Takes place in the proximal convolutedtubule and loop of Henle. In this step the essential components are reabsorbed from the nephron into the blood. In figure 9 drew arrows (using a different color than figure 8) to show the direction of flow from nephron to blood. Takes place in the distal convolutedtubule, In this step ions are discarded from the body of they are in excess. Antibiotics that are not used by the body, histamines etc. are discarded from the blood and secreted into the nephron. In figure 10, draw arrows to show the direction of flow from peritubular capillaries to the nephron. List the substances that are present n the urine at this stage. When he blood pH is lower than normal what will you see during this phase of urine formation to return the pH back to normal? How will this effect the pH of the urine? This step takes place in the collecting duct if the concentration of the blood is too high. If the body is dehydrated (the concentration of the blood is high) what could be a way of bringing the concentration back to Drinking back to normal?

Explanation / Answer

ANSWER:

1) UREA,URIC ACID AND CREATININE

2) The renal venous blood then mixes into the systemic circulation and raises the pH of the systemic blood towards normal.

3) Probably compensated by renal excretion of base, i.e. NaHCO2 or KHC03.

4) Eating a diet rich in cooked meat can increase the amount of creatinine in your body and drinking more water
