Question

Please write a preface for my school project files . (200 words approx.) On excretory system

Answer 1

The Excretory System is the system in the body that excretes waste and the most important factors about the excretory system are the organs involved, the main functions of the system/working with other systems, and the problems if some organs are lost. This system is often mistaken to only correspond when people go and use the bathroom, however, the Excretory System actually consists of the lungs, skin, kidneys, urinary bladder, ureter, urethra and the liver. The lungs take in oxygen and they exchange that for the waste product- carbon dioxide. The skin sweat to take out the dirt, bacteria, and the dead skin cells out of the pores to cleanse themselves. So the excretory system does do a lot with other parts of the body. However the other parts of the excretory system are their own.(For more information, check the tab, Other Body Systems) The kidneys of the body are connected to the liver and digestive system to take surplus amount of water and waste to be taken out of the system. Also the ureter and the urethra take the waste from the kidneys to the Urinary Bladder to be taken out of the body.( for defintions for the underlined words, go to the tab, Diagrams)
 So the main functions of the Excretory System is to take waste out of the body. If one organ is lost or doesn't function correctly, machines can help or you can just die- so take care of yourself. If you are losing an Organ from the Excretory System you got a huge problem. This system's purpose is to take used material/waste out of the body. For example, if you lost the bladder, you would either need a bag to hold your urine or a machine to act like a bladder to take out the urine/used fluid out of the body. Therefore, without the Excretory system, we would literally be full of waste and most likely die of early age without the most disgusting system in the body- the Excretory system.
