About the process that returns glucose to the blood
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 30A
Correct answer :
The correct answer is option (C) Reabsorption.
Explanation of Solution
Explanation/justification for the correct answer :
Option (C) Reabsorption. Much of the lost water and useful substance such as glucose and minerals, are reabsorbed back into the capillaries surrounding the renal tubule. This process is called reabsorption. So, the correct answer is option (C).
Explanation for incorrect answer :
Option (A) excretion. Excretion is the process of removing or expelling waste material. It is the function of the kidney but the return of glucose to the blood is the process of reabsorption. So, this is an incorrect option.
Option (B) filtration. It is the function of the kidney but the return of glucose to the blood is the process of reabsorption. So, this is an incorrect answer.
Option (D) exhalation. Exhalation is the act of taking out air from the lungs. It is a function of the respiratory system. So, this is an incorrect answer.
