Digestive system song for Bio. Yo Yo Yo You hungry? Thats right! We be telling you about the Digestive System Thats right. Now listen up. When you chew down on your food Your teeth grind it down Incisors to bite it Canines tear and hold it down Molars chew it up and mix it with your saliva From your salivary glands Yo we aint liars! Amylase in your saliva breaks down the carbohydrates Then the bolus goes down unblocked by the epiglottis In a tube to your stomach, its called an esophagus Using muscular contractions known as peristalsis The bo-lus goes down to your stomach Has a pH of 2, its very acidic Enzyme pep-sinogen will change into pepsin The bolus turns to chyme as it churns in the stomach Break --- However there are other organs at work Like your liver, dont be scared Hes not a jerk. Your liver makes bile that emulsifies fats In the small intestines, what dya think o that? It detoxifies blood and stores glycogen Its so important that you cant live without it The bile it makes is stored in the gall bladder Connected to the duodenum but else it dont matter The pancreas makes enzymes to break down the proteins And the sugars and the fats from what youve been eating It also makes a hormone letting glucose in your cells, Lowers the blood sugar level, its called in-su-lin Break----- When the chyme enters the small intestine The food is too acidic so its time For the pancreas to release bicarbonate ions That basify the chyme Hey are you buying? The small intestine is made of 3 parts The duodenum, jejunum, and il-e-um The inside is covered with thousands of villi To up the surface area, its really fly All the enzymes and juices start digesting the food And nutrients by the ileum are absorbed Break------ Then whats left over enters the colon Where the water is reabsorbed by the body The colon compacts the rest of the waste And bacteria munch it making vitamin K The rectum is at the very end It holds the waste till it can descend Anal sphincters in the anus help do just that And now that were finished you can see it ain't all that G cells in the house with our homey Peabody Yo this the end, peace out to everybody
