Hello! I am hamburger and now I will start my journey of digestion and absorption. So let's go! Olivia is hungry.
I am in Olivia's mouth. She start chewing me up which is known as mechanical digestion and her amylase in her saliva is breaking my starch down (chemical digestion).
Now as she is done I am sent to oesophagus as a bolus and which is the direct path to stomach.
wohooh! exciting! Ok now I have landed in Olivia's stomach . I am merged with gastric juices, pepsin, and enzyme that breakdown my proteins. Now I'm a thick liquid known as chyme.
HELLO! now I am here in small intestine. I am mixed with enzymes (produced by pancreas) and bile (produced by liver and stored in gallbladder) for breakdown. now I am moving along and with the help of villi my nutrients are absorbed in the blood vessels (diffusion).
hurray! I've arrived to large intestine and in this part absorption of water and minerals take place and what is left of me is known as feces. I'm pushed to the rectum and deposited when Olivia needs to take me out of her system. Hope you remember me when you eat hamburger next time.
