Question:

Typically, the water lost in the urine is greater than that lost in the breath. In the case of severe blood loss, however, the urine output is decreased from normal and will decrease further with time. Describe two independent physiological mechanisms that account for this decreased urine output.

Normal Physiology Of kidney function

In normal circumstances, the kidney receives 20-25% of total resting cardiac output to maintain the acid-base balance of the body and excrete harmful end products of protein metabolism.

The function of the kidney is dependent on GFR and antidiuretic activity. GFR is controlled by renal autoregulation, Neural regulation by ANS, and hormonal regulation through renal angiotensin and ANP These all systems involuntarily regulate the GFR. Nephron reabsobtion and secretion mechanism is controlled by electrolytes and Antidiuretic hormone.
