Ian: Thank you Haley we will make sure that we are on top of that. Today we have a very special documentary. Our documentary is going to be on our very own world, we are going to go deeper inside the excretory system. So sit back and relax and take an adventure into the excretory system.....======

Ian: The excretory system. The excretory is the system that is responsible for releasing waste that your body has to get rid of such as excess water and urea which is chemical that come from the breakdown of proteins. The excretory system includes the kidneys, lungs, skin, and the bladder. Today we will be explaining how the kidneys, lungs and the bladder work in the excratory system. We are here for all the answers explaining everything in our world, the excretory system.======

Haley: Thank you ian for that wonderful introduction! Now lets start out with the kidneys! The kidneys filter your blood and your urine. The liquid that and urine that is left over will go through to the bladder. Your kidneys lay on either side of your lower spine and are bean shaped! Without your kidneys your blood couldn't be filtered and your blood would become polluted so to speak and your body couldn't run on it so you would die. The left kidney lies a littler higher than the right kidney and the kidneys are about 10 cm long and about 6.4 cm wide. The kidneys have a few different functions, the main purpose of the kidney though is to seperate urea, mineral salts, toxins and other waste products from the bblood. Each kidney contains about a million tiny filtering units called nephrons and the nephrons produce urine. The nephron filters water in stages. First waste and ohter materials that your body needs such as glucose, get filtered and get taken out of the blood. Then the needed material is returned to the bllod and whats left over gets eliminated from the body which ends up to be or urine.======

Molly: Moving on! Now we are going to talk about lungs! You may only think that the bladder and kidneys get rid of waste but the lungs do too. In your skin sweat glands remove water and urea because they are excreted in perspiration. When you exhale carbon dioxide and some water are removed by the body from the lung. For example, when you breathe in cold air you can see the water in your breath. The first thing that you need to know about the lungs is that, as air passes threw each lung and flows narrower and narrower bronchioles until it reaches the alveoli. The lungs are dome shaped and located in the rib cage. Two thin layers of tissue called the pleura cover each lung and the inside of the rib cage. These layers or membranes, slide back and forth over each other as we breathe. Each lung is between 10 and 12 inches long. your lungs are 90% air and 10% tissue. The inside of your lungs looks like a giant sponge. It is a mass of fine tubes, the smallest of which end in tiny air sacs called alveoli. These air sacs have very thin walls which are criss-crossed with hundreds of tiny blood vessels called capillaries. There are 200 million or so of these air sacs, and if they were to spread out they would cover a piece of ground roughly the size of a tennis court. These are all common facts about the lungs.======

Ian: Lastly we are going to talk about the bladder, liver, and intestines. The large intestine are 1.5 meters long. The small intestine is 6 meters long and 2.5 cm wide. The small intestine brings food to the liver. The small intestine is where the most extensive part of digestion occurs. Most food products are absorbed in the small intestine. The large intestine is responsible for absorption of water and excretion of solid waste material. Food and waste material are moved along the length of the intestine by rhythmic contractions of intestinal muscles;The liver is the largest glandular organ of the body. It weighs about 3 lb. It is reddish brown in color and is divided into four lobes of unequal size and shape. The liver lies on the right side of the abdominal cavity beneath the diaphragm. The liver has many functions. Some of the functions are: to produce substances that break down fats, convert glucose to glycogen, produce urea, make certain amino acids, filter harmful substances from the blood (such as alcohol), storage of vitamins and minerals and maintain a proper level or glucose in the blood. The liver is also responsible fore producing cholesterol. It produces about 80% of the cholesterol in your body. The bladder is Where the urine gets stored. The bladder lies in your pelvis. The bladder normally contains about (12oz) of urine. The bladder's main function is to store and release urine. Nerves in the bladder tell you when it is time to urinate. This all common facts about the bladder.======
