Describe the three processes involved in urine formation: filtration, secretion and reabsorption. Discuss the formula: E = F – R + S.
Given: A patient’s GFR (glomerular filtration rate) is 125 ml/min, and his urine is produced at a rate of 1.25 ml/min.
(A) By what factor is the inulin concentrate in his urine.
(B) The concentration of glucose in his plasma is 5 mmol/l. His renal reabsorption of glucose is completely inhibited. What would be the concentration of glucose in his urine?
(answer parts a and b)
Glomerular filtration is affected by forces that oppose and promote filtration. What are these forces and explain the theory behind net filtration pressure?
