Counter current mechanism :

i. It operates in all vertebrates.
ii. It produces hypertonic urine.

Read the following statements about urine formation :

i. ultrafiltration doesn’t need any energy expenditure by kidney cells.
ii. selective reabsorption of glucose, water, urea, hormones, amino acids etc takes place through passive transport.
iii. PCT cells have many microvilli along with few mitochondria since most of nutrients are absorbed passively.

If in glomerular capillaries, pressure of blood is 75 mm Hg, osmotic pressure of plasma proteins is 30 mm Hg, and hydrostatic pressure of fluid in renal tubule is 25 mm Hg then net force or the filtration pressure will be calculated as :

The hormone with enzymatic action which catalyses conversion of angiotensinogen into angiotensin is :

Vasopressin is a hormone involved in regulation of urine formation. It is secreted from :

Read the following about renal threshold :

i. The renal threshold of glucose is 180 mg/100ml of blood.
ii. If blood level of glucose exceeds 180mg, it leads to diabetes insipidus.
iii. If blood level of glucose exceeds 180mg, it leads to diabetes mellitus.
