Theme: Talkshow Script: //(theme song)// C: Hello, and you are watching "The Body View", live with Dr. Abby, Dr. Kendall, And myself Dr. Chelsea. K: Today's topic is the excretory system. Before we get started we might want to have a little back round on the excretory system. The excretory system means a removal of waste substances from the body. C: The excretory system's job is to remove waste products from the body.It collects wastes produces by cells and removes the wastes from the body. A: In order to do that, some functions of the system are to collect water and filter body fluids,remove and concentrate waste products of the body fluids and return other substances to body fluids as necessary for homeostasis, and eliminate excretory products from the body. C: Yes, and the excretory system has main organs to help it function, which include the bladder, the kidneys, the aorta, the urethra, and the ureters. K: So Dr. Abby I understand that you have research about the excretory system back in medical school, do you think you could tell the truth behind it? A: I think I'll start off with talking about the kidneys. They act as a filter to the body. The nephrons are small molecules in the kidney that act as the filters. They kidneys will take out all the harmful molecules from our bloodstream and leave all the good molecules in our blood. When the kidneys filter the blood it produces 1.5-2 liters of urine a day. C: To add onto what Dr. Abby said, each kidney is the size of your fist, and your kidneys are connected to you bladder by tubes called ureters. You also have hundreds of nephrons in your kidneys. The kidneys also produce hormones that tell the body to produce red blood cells. A: Also t he kidneys produce hormones that affect the function of other organs. K: Thanks for all the information on the kidneys. Now we can talk about the bladder. The bladder's looks like a balloon and it's main function is to hold urine. When the bladder is full it expands and than lets the urine pass into the urethra. A lining of muscle surrounds the inner layer of the bladder. So when the bladder is full, the muscles will tighten, which will allow you to go to the bathroom. A: Thank you Doctor Kendall for the interesting information about the bladder. C: There are two more organs in the Excretory System, the aorta and the ureters. The ureters are two narrow tubes, in which urine flows from the kidney to the urinary bladder. K: The aorta is the largest artery in the body, and the urethra is a small tube, in which the urine leaves the body through. A: It looks like its time to wrap things up. Thank you for watching "The Body View." And come join us next week for information on the nervous system.
