Different parts of the BigMac would transform at different time in the digestive system.]]> 2017-02-20 08:04:17 UTC https://padlet.com/dorislujia/3zpmv6loy0ew/wish/154875866 dorislujia https://padlet.com/dorislujia/3zpmv6loy0ew/wish/155428714 2017-02-22 13:17:34 UTC https://padlet.com/dorislujia/3zpmv6loy0ew/wish/155428714 dorislujia https://padlet.com/dorislujia/3zpmv6loy0ew/wish/155429584 When the BigMac is ingested, the bread of the BigMac got digested in the mouth (by amylase in the saliva). Also, the entire BigMac transformed to smaller pieces ( by chewing).]]> 2017-02-22 13:21:44 UTC https://padlet.com/dorislujia/3zpmv6loy0ew/wish/155429584 dorislujia https://padlet.com/dorislujia/3zpmv6loy0ew/wish/155430742 Next, those smaller pieces goes to stomach through esophagus by peristalsis.The stomach kills pathogens in food and start digestion. Beef got digested in this section by stomach acid ( mainly composed of HCl).The food mixture goes into small intestine.]]> 2017-02-22 13:26:56 UTC https://padlet.com/dorislujia/3zpmv6loy0ew/wish/155430742 dorislujia https://padlet.com/dorislujia/3zpmv6loy0ew/wish/155443275 The food juice enters small intestine and thus the absorption begins.The small intestine continues the process of breaking down food by using enzymes released by the pancreas and bile from the liver.The walls of the small intestine absorb the digested nutrients into the bloodstream and the nutrients to the rest of the body.]]> 2017-02-22 14:05:12 UTC https://padlet.com/dorislujia/3zpmv6loy0ew/wish/155443275 dorislujia https://padlet.com/dorislujia/3zpmv6loy0ew/wish/155446982 Finally, all the remaining substance goes down to the large intestine.The large intestine absorbs water and changes the waste from liquid into stool. The rectum stores stool until it pushes stool out of the body during a bowel movement.
That's the end of the journey of the BigMac.]]> 2017-02-22 14:14:17 UTC https://padlet.com/dorislujia/3zpmv6loy0ew/wish/155446982 mahipauldayaram https://padlet.com/dorislujia/3zpmv6loy0ew/wish/161699019
Could go into some more detail about the specific enzymes used. 

The diagram is very useful too.]]> 2017-03-22 02:30:11 UTC https://padlet.com/dorislujia/3zpmv6loy0ew/wish/161699019 https://padlet.com/dorislujia/3zpmv6loy0ew/wish/320202195 2019-01-14 09:35:18 UTC https://padlet.com/dorislujia/3zpmv6loy0ew/wish/320202195 https://padlet.com/dorislujia/3zpmv6loy0ew/wish/320202206 2019-01-14 09:35:21 UTC https://padlet.com/dorislujia/3zpmv6loy0ew/wish/320202206 https://padlet.com/dorislujia/3zpmv6loy0ew/wish/320202230 2019-01-14 09:35:27 UTC https://padlet.com/dorislujia/3zpmv6loy0ew/wish/320202230 https://padlet.com/dorislujia/3zpmv6loy0ew/wish/369833693 2019-07-01 14:19:42 UTC https://padlet.com/dorislujia/3zpmv6loy0ew/wish/369833693 https://padlet.com/dorislujia/3zpmv6loy0ew/wish/409429178 2019-11-11 13:04:27 UTC https://padlet.com/dorislujia/3zpmv6loy0ew/wish/409429178 nataliaf5012 https://padlet.com/dorislujia/3zpmv6loy0ew/wish/1335504819 i had a very hard time finding just the 4 steps but i finally found this]]> 2021-03-21 23:32:24 UTC https://padlet.com/dorislujia/3zpmv6loy0ew/wish/1335504819 https://padlet.com/dorislujia/3zpmv6loy0ew/wish/1362230230 2021-03-28 23:59:33 UTC https://padlet.com/dorislujia/3zpmv6loy0ew/wish/1362230230
