You Are Alive Research Paper

You're alive…. I am alive… But there is a problem with that. Well, how to I say this without being disgusting? Umm…. As a normal human being, we all produce waste. This waste comes from cells, as metabolic waste. This includes excess carbon dioxide, salts, and urea. Urea is a toxic compound that is produced when amino acids are produced. And that waste leaves our body. The system that gets rid of that waste is the excretory system. This system is consisted of the skin, lungs,the kidneys, and all their helper organs.

The main organ of this system are the kidneys. They are located on the right and left side of your spinal column. A tube called the ureter leaves each kidney. The ureter carries urine to the urinary bladder, a sac like organ where …show more content…
The outer part is called the renal cortex and the inner part is called the renal medulla. Nephrons are what make the kidneys work. But what are they? They are small independent processing unit that contains a glomerulus, bowman's capsule, capillaries, veins, arteries, the Loop of henle, and a collection duct. As we go along this speech you will figure out what some of the parts are. The nephrons have to filter the blood, but where do they get it from? The constant supply of blood comes from the arteriole, a venue, and a network of capillaries connecting them. Blood that enters the nephron goes into the glomerulus which is a network of capillaries that are inside a cupped shaped structure called the Bowman's capsule. The blood that flows into the nephron is under pressure, and the Bowman's capsule is permeable… Well, you can already tell what will happen. Basically, fluid flows into the capsule, this process is known as filtration, no durr… Anyway, slats, water, vitamins, urea, glucose, and amino acids end up in the capsule. These materials are know as filtrates. The blood also contains proteins plasma, cells, and platelets, but these materials are too big to pass into the capsule, remain in the
