Colloid, Blood, and Kidney: Chemistry Topics to Support Meaningful Learning for Biology Students

Abstract

Biology students desperately need chemistry because chemistry explains in detail why a biological process occurs. However, there are still many biology students who consider chemistry a difficult subject to study. This topic supports meaningful learning for biology students. Biology topics that are closely related to colloid topics are the nature of blood as colloids, the ability of the kidneys to cleanse the blood, and the working principle of a dialysator that can replace the kidneys in cleansing the blood.
