Which substance is constantly processed by some excretory organs even though it is not excreted by the excretory system?
Answer (3)
Answer: The correct answer is-
**Blood. **
Excretion is mechanism of removal of waste material and excess of water from the body. Organs of excretion (such as kidney, skin, large intestine, lungs, and liver) form the excretory system.
The kidneys (part of urinary system) are considered as the main excretory organ in human that perform continuous filteration of blood to remove nitrogenous waste, excess of water and salts out of body . It forms urine that is excreted out of the body.
Therefore, blood is constantly processed by some excretory organs and the waste products are excreted out of the body without the excretion of blood.
Blood is constantly processed by some excretory organs even though it is not excreted by the excretory system.
The substance that is constantly processed by excretory organs but is not excreted is blood. The excretory system removes waste from blood through organs like the kidneys, liver, lungs, and skin; however, the blood itself remains in the circulatory system. Thus, blood is filtered and processed while retaining its essential functions in the body.
