Question

a) Differentiate between following: (only two difference).

i) Renal cortex and renal medulla

ii) PCT & DCT

iii) Renal artery and renal vein​

Answer 1

Answer:

Explanation:enal cortex Renal medulla

It forms the outer layer of the kidney. It forms the inner layer of the kidney.

It contains the Malpighian corpuscles, the proximal and distal parts of the renal tubule. It contains elements of Henle's loop and the collecting tubules.

PCT occurs after the Bowman's capsule while DCT occurs after the loop of Henle. PCT is mainly involved in the reabsorption whereas secretion occurs in the DCT. The main difference between PCT and DCT is that PCT is the function of each part in the nephron.

Renal artery carries mineral rich, oxygenated blood from the heart to the kidneys for nutrition and cellular respiration. Renal veins carry deoxygenated blood after waste products have been removed via glomerular filtration back from the kidneys to the heart.

Answer 2

Answer:

PCT: Proximal convoluted tubule (PCT) refers to the convoluted portion of the nephron between Bowman's capsule and the loop of Henle. DCT: Distal convoluted tubule (DCT) refers to the convoluted portion of the nephron between the loop of Henle and the collecting duct

The renal artery branches off from the lower part of the aorta and provides the blood supply to the kidneys. Renal veins take blood away from the kidneys into the inferior vena cava. The ureters are structures that come out of the kidneys, bringing urine downward into the bladder.hope uu get the answer!!
