Question

What is the characteristic of the metanephric kidney?
A. Hypotonic urine production
B. Excess secretion of uric acid
C. Loop of Henle
D. Hormone production

Answer 1

Hint:Metanephros, the permanent kidney in reptiles, birds, and mammals, emerges in human embryos from the lower part of the Wolffian duct by the 10th week and replaces the mesonephros embryonic structure.

Complete answer:Several processes regulate the osmolarity of the urine. Excretion of excess water contributes to the formation of hypotonic urine and the formation of hypertonic urine results from the excretion of excess solutes.
Hyperuricemia is an elevated level of blood uric acid. The standard upper limit is 6.8 mg / dL, and it is considered saturated with anything over 7 mg / dL, and symptoms can occur. This high level is due to increased output, reduced uric acid excretion, or a combination of the two processes.
Henle Loop, a long U-shaped part of the tubule that carries urine to reptiles, birds, and mammals inside each nephron of the kidney. The key feature of Henle’s loop is to recover urine from water and sodium chloride. Glands create hormones and send them through the bloodstream to the different tissues in the body. To tell them what they should do, they give signals to those tissues.

Below is the picture of the loop of Henle.

Hence the correct answer is option C, Loop of Henle.

Note: The metanephric kidney grows from the nephrotomy’s posterior portion (metanephros), while the remaining portion is killed. Nephrons are well distinguished from the capsule of Bowman, PCT (proximal convoluted tubule), DCT (distal convoluted tubule), and Henle loop, e.g., reptiles, birds, and mammals.
