Question
The kidney play an important role in the regulation of blood pH which is 7.35 to 7.45. The physiology of kidney help in the regulation of blood pH by excreting excess acid and base. The kidney maintain blood pH homeostatis by excreting hydrogen ion present in the blood and reabsorbing biacrbonate from urine.
When the blood pH is low or H+ is high, kidney reabsorb more bicarbonate from the filterate . On the other hand, when blood pH is high, kidney excrete more bicarbonate ion in the urine and therefore more ammonium(NH3) is excreted. Therefore, the kidney maintain normal ph of blood by excreting excess H+ into urine and reabsorbing bicarbonate from urine.

Chronic kidney disease impairs the kidneys ability to contribute to blood volume changes that help to maintain normal blood pressure levels. Consider a condition that impaired the kidneys ability to produce the hormone renin from the JG cells in Bowman’s capsule, how would that alter the kidney’s contributions to maintaining blood pressure levels? Make sure to discuss specific regions of the nephron that are involved in kidney function.

PART A: Discuss how buffers, ventilation, and the kidneys all work together to regulate blood pH. PART B: Discuss the changes that occur in heart rate, stroke volume, and cardiac output from rest to maximal exercise. Why do they occur, and how do they interact with each other to maintain adequate cardiovascular support for exercise?

1. The correct functions of your lungs contribute to the normal pH level of between 7.35 and 7.45 in your blood. If your lungs do not exchange and remove carbon dioxide from your blood, the blood pH will change. A reading of pH 6.4 of your blood indicates: A. no health risk, as part of normal pH changes in your body that in this case bring it closer to neutral pH. B. a health problem due to the concentration of...
