SCI 228 WEEK 1 One of the first topics that we need to explore is our digestive tract. Each step of digestion has its own function. Chewing, for example, increases the surface area of food particles (physical digestion) so that the enzymes in the mouth can start breaking the nutrients down (chemical digestion). Review the two links and complete the lab assignment stated below.
Week 1 Assignment:
Part 1
There are several parts to this iLab. Part 1 consists of listing all of the parts of the digestive system with either a list or photo. Many people take a screenshot and use it for Part 1. Feel free to also list the parts as well if you cannot figure out how to take a screenshot.
Part 2
Part 2 technically consists of two parts. The first one includes describing the location of each body part. For example, the appendix is located on the right side of the body under the ascending colon. Another way to do this part would be to write out the parts and put a location/description next to it. The second part of Part 2 for this section is to describe the manner in which you will retain the information of where each body part is located. An example would be, "I will remember the location of each body part by reviewing the photo and memorizing each location." Some classmates develop interesting methods of memorizing where all of the parts are located, like using mnemonics. Feel free to be creative.
Part 3
For Part 3, which is in a Word document (or the same document that you have been using for Parts 1 and 2), please take the overall categories (mouth, small intestine, esophagus, stomach, and large intestine) and label them with the appropriate mechanisms that occur in each of them (propulsion, absorption, chemical digestion, and mechanical digestion). Please remember that each digestive system part mentioned above may be involved in more than one of the mechanisms.
Part 4
For Part 4, please define each mechanism (propulsion, absorption, chemical digestion, and mechanical digestion) with two to three sentences each.
