Glomerular Filtration Rate

Read the following statements and choose the correct option (i) Glomerular filtration rate in a healthy individual is about 180 ml/day (ii) All constituents of plasma pass into lumen of Bowman's capsule (iii) 70 - 80% of electrolystes and water are absorbed in PCT (iv) Angiotensin II increases the glomerular blood pressure and GFR (v) Counter current system contribute in concentrating the filtrate

Assertion: Pregnant women may show some presence of glucose in their postprandial urine although they have no diabetes. Reason: In pregnant women the glomerular filtration rate is slightly increased. As a result the tubular load of glucose exceeds the tubular maximum for glucose reabsorption.

Complete the following paragraph by selecting the option that correctly fils the blanks (i)- (iv) The kidney have built-in mechanisms for the regulation of glomerular filtration rate. One such efficient mechanism is carried out by (i)._____ It is a special sensitive region formed by cellular modifications in the (ii)._________ and the (iii)._________ at the location of their contact. A fall in GFR can activate the JG cells to release (iv).________ which can stimulate the glomerular blood flow the thereby brings GFR back to normal

Assertion: The kidneys have built in mechanisms for the regulation of lomerular filtration rate (GFR). Reason: ANF mechanism is one such efficient mechanism.

Assertion: Glomerular filtration requires expenditure of energy bu kidney. Reason: Glomerular filtration occurs because pressure in the glomerular capillaries is lower than the pressure in Bowman's capsule

Assertion : Squamous epithelium helps in glomerular filtration. Reason : It forms inner lining of Bowmen's capsule.

Glomerular filtrate is
