Complete all parts of the following sections on the appropriate lab report:
A. Provide background information for your experiment (suggested length of 2–3 pages) by doing the following:
1. Label at least six of the digestive structures in the attached “Digestive System Diagram – Form A.”
2. Describe the function of each labeled organ or accessory organ.
3. Summarize mechanical and chemical digestion.
4. Provide at least six examples of enzymes that digest carbohydrates, proteins, and lipids.
5. Summarize two experiments you have researched (e.g., from scholarly journals, websites, etc.) that involve enzyme activity in food sources.
B. Describe the design plan for your experiment (suggested length of 1–2 pages) by providing the following:
1. A problem statement in which you do the following:
a. Discuss the independent and dependent variables for your experiment.
b. Explain the controlled variables for your experiment.
2. A hypothesis in which you do the following:
a. Predict the relationship that exists between the independent and dependent variables.
b. Explain how you reached your hypothesis.
3. An explanation of your procedure in which you do the following:
a. Describe the steps of your experiment.
b. Explain how you will measure the results (i.e., the tools and strategies you will use to determine the outcome).
c. Create a data table template that you will use to record the results.
d. Explain how you will ensure that the controlled variables are held constant.
C. Conduct the experiment and present your results and conclusions (suggested length of 1–2 pages) by providing the following:
1. The results of the experiment in which you do the following:
a. Record the data for your experiment using the blank template you created in part B3c.
b. Create a visual representation of your results.
c. Explain the results of the experiment with reference to the independent and dependent variables.
2. A conclusion in which you do the following:
a. Summarize the results of your experiment.
b. Explain how your results compare with your hypothesis (i.e., does the data confirm or refute your hypothesis?).
c. Explain how your findings relate to chemical digestion.
D. Explain the interdependency of the digestive system, respiratory system, and cardiovascular systems in providing cells with necessary nutrients (suggested length of 1–2 pages) by doing the following:
1. Create a flow chart that shows the step-by-step absorption of carbohydrates, proteins, and lipids.
2. Describe each of the steps involved in the absorption of carbohydrates, proteins, and lipids.
3. Explain how nutrients are delivered to the cells from the capillaries.
4. Explain the role of hepatic portal circulation in transporting nutrients.
5. Describe how oxygen is delivered to the cells for use in metabolic processes.
6. Summarize how the urinary system functions in removing wastes from the body.
E. If you choose to use outside sources, include all in-text citations and references in APA format.
