Question

Which part of the nephron that exists in the outer zone of the kidney?
A. Loop of Henle
B. PCT
C. DCT
D. Bowman’s capsule

Answer 1

Hint: Kidney is an organ found in the human body which forms a part of the human excretory system. Kidneys are bean-shaped organ reddish-brown in color. They perform the function of osmoregulation, the formation of urine, and acid-base balance. The smallest unit which is considered as the functional unit of the kidney is the nephron.

Complete answer: Human kidney is reddish-brown in color and is placed on the right and left retroperitoneal space. It is one of the important organs of the human body which plays an important role in the excretory system of the body. Kidneys consist of nephrons which are the smallest structural and functional unit of kidney. The kidney is made up of two portions called the medulla and the cortex. Cortex is the rough outer part of the kidney while the soft inner portion of the kidney is the medulla. The nephron is responsible for urine formation in the human body. The nephron is made up of two portions called the renal corpuscle and the renal tubule. The renal corpuscle consists of a bunch of capillaries called glomerulus which is encompassed in a cup-shaped structure called the bowman’s capsule. The renal tubule starts from the capsule and ends in the outer zone of the kidney that is the cortex. The renal tubule consists of a PCT, loop of Henle, and DCT. Proximal convoluted tubule (PCT), distal convoluted tubule (DCT), and loop of Henle are found in the inner portion of the kidney called the medulla whereas the bowman’s capsule is found in the outer zone of the kidney that is the cortex.

So, option D is the correct answer.

Note: Nephron and neuron are totally two different structures which are found in the human body, neuron is the basic microscopic structural unit of the brain whereas nephron is the microscopic structural unit of the kidney. Damaging of the nephron causes diseases like diabetic nephropathy.
