Final answer:
Typical resting renal blood flow is about 1050 mL/min, and with a hematocrit of 45, the renal plasma flow is 578 mL/min. The kidneys produce about 125 mL/min of filtrate in males and 105 mL/min in females, reflecting the kidneys' role in fluid and electrolyte balance.
Step-by-step explanation:
Typical renal blood flow is about 1050 mL of blood per minute under resting conditions. When considering the hematocrit level of 45, the renal plasma flow is 55 percent of the total blood flow. Therefore, the renal plasma flow would be 578 mL of plasma per minute. The Glomerular Filtration Rate (GFR) is crucial and is determined as the volume of filtrate formed by the kidneys each minute. Under resting conditions, the heart pumps about 5 liters of blood per minute, with approximately 20 percent or 1 liter entering the kidneys to be filtered, resulting in about 125 mL/min of filtrate produced in males and 105 mL/min in females. This filtration process is a critical measure of renal function and reflects the kidneys' capacity to manage fluid and electrolyte balance in the body.
