Important Questions on Human Excretory System
What is hilus in a kidney?
List the various parts of uriniferous tubules.
Explain the structure of uriniferous tubule.
Uriniferous tubule is also known as nephron.
Explain the homeostatic control mechanisms in human beings.
The organs A of a person have been damaged completely due to which too much of a poisonous waste material B has started accumulating in his blood, making it dirty. In order to save this person’s life, the blood from an artery in the person’s arm is made to flow into long tubes made of substance E which are kept in coiled form in a tank containing solution F. This solution contains three materials G, H and I in similar proportions to those in normal blood. As the person’s blood passes through long tubes of substance E, most of the wastes present in it go into solution. The clean blood is then put back into a vein in the arm of the person for the process of circulation.
Identify 'E'.
