About the loop of Henle.
Introduction:
The excretory system is the system of an organism's body that performs the function of excretion, the bodily process of discharging wastes. Several parts of the body are involved in this process, such as sweat glands, the liver, the lungs and the kidney system. The kidneys maintain homeostasis by removing wastes and excess water from the body and by maintaining the pH of the blood. The kidneys are the major excretory organ in the body. It is a bean-shaped organ that is involved in urine formation performs filtration of blood.
Answer to Problem 28A
Correct answer :
The correct answer is option (A) Renal tubule.
Explanation of Solution
Explanation/justification for the correct answer :
Option (A) Renal tubule. The loop of Henle is found in Bowman’s capsule. Water and substances dissolved in the water, such as the nitrogenous waste product called urea, are pushed through the capillary walls into the Bowman’s capsule. The filtrate collected in the Bowman’s capsule flows through the renal tubule that consists of the convoluted tubule, the loop of Henle, and the collecting tubule. So, the correct answer is option (A).
Explanation for incorrect answer :
Option (B) glomerulus. Blood enters each nephron through a long tube that is surrounded by a ball of capillaries called the glomerulus. Here, the loop of Henle is not located. So, this is an incorrect option.
Option (C) Bowman’s capsule. The glomerulus is surrounded by a structure called Bowman’s capsule. Here, the loop of Henle is not located. So, this is an incorrect answer.
Option (D) urethra. The urethra is a tube that connects the bladder’s neck to the opening of the urethral on external genitals, where urine exits the body. Here, the loop of Henle is not located. So, this is an incorrect answer.
