1.	The size of filtration slits of glomerulusA. 10 nmB. 15 nmC. 20 nmD. 25 nm.
Answer» Correct Answer - D Blood drained from a convenient artery is pumped into a dialysing units (also called artifical kindney) after adding an anticoagulant like heparin. The unit contains a coiled cellophane tube surrounded by a fluid (dialysihg fluid ) having the same compostition as that of plasma except the nitrogenous wastes. The porous cellophane membrane of the tube allows the passage of molecules based on concentration gradient. As nitrogenous wastes are absent in the dialysing fluid, these substances freely move out, thereby clearing the blood. The cleared blood is pumped back to the body through a vein after adding anti-heparin to it.
