17. HOW DOES H2O AFFECT HUMAN EXCRETION? BY:Elena Rubio Maria Camila Martinez

18. Drinking to much water affects human excretion Ingesting more water than you need can increase your total blood volume. And since your blood volume exists within a closed system - your blood circulatory system - needlessly increasing your blood volume on a regular basis puts unnecessary burden on your heart and blood vessels. Your kidneys must work overtime to filter excess water out of your blood circulatory system. Your kidneys are not the equivalent of a pair of plumbing pipes whereby the more water you flush through your kidneys, the cleaner they become; rather, the filtration system that exists in your kidneys is composed in part by a series of specialized capillary beds called glomeruli. Your glomeruli can get damaged by unnecessary wear and tear over time, and drowning your system with large amounts of water is one of many potential causes of said damage.
