Explanation: DCT is distal convoluted tubule. It is the portion of kidney nephron between the loop of Henle and collecting tubule.

Explanation: Urea synthesis takes place in liver because Enzyme arginase is present in liver. Urea cycle takes place to form urea.

Explanation: Yellow color of urine is due to Urochrome. It is a linear tetrapyrrole compound is degradation products of the cyclic tetrapyrrole heme.

Explanation: Vasopressin is called an Antidiuretic hormone (ADH). Vasopressin stimulates reabsorption of water and reduction of urine output.

Explanation: Juxta glomerular cells are cells in a kidney that synthesize the store and secrete the enzyme rennin. They are smooth muscle cells mainly in the wall of afferent arterioles and some in efferent arterioles that deliver blood to glomerulus.

Explanation: Bowman’s capsule is a cup like a sac at the beginning of tubular component of nephron, it performs first step in filtration of blood to form urine. Liquid which collects in Bowman’s capsule is plasma minus blood proteins.

Explanation: Renal Pyramid is cone shaped tissues of the kidneys. In human renal medulla is made up of 18-20 of these conical subdivisions. It consists of tubules that transport urine from cortical to calyces in which urine is collected before it passes through the ureter.

Explanation: Urea synthesis occurs in the liver. Since there is an arginase enzyme present in the liver the synthesis of urea occurs in liver.
