Excretory system, on the other hand, is a system in the body that removes homeostatic wastes from the body by using a process which is called excretion. Excretory includes organs such as liver, sweat glands, lungs. Among this, the liver plays a critical role in the secretion of homeostatic wastes in the form of fluids.

Additionally, drought is a period where precipitation is below average and thus resulting in prolonged shortages of water supply as far as both ground and surface water are concerned. This can last for several months or even for years.
