ENERGY AND THE HUMAN BODY

All body systems need energy to function. The body fuels cells with the nutrients and gases necessary to function properly. Our body takes in oxygen and circulates it through the bloodstream. Many chemical reactions in the body require cellular energy and need oxygen to drive these reactions. Some of these reactions are used to break down food and metabolize what we eat, which are a part of the digestive system.SHOW LESSAs Tanya ages, her metabolism decreases. The food she eats impacts the energy she needs to function. Not enough food or too much food can also impact her body functions. What can she do to get the proper nutrients but not gain weight? Let us take a closer look at the digestive and respiratory systems to learn about how they function in Tanya’s body and how Tanya gets energy.The body needs energy to live. The digestive and respiratory systems work to provide this energy with nutrients and oxygen. We eat food to provide energy to our cells. The digestive system breaks the food down into smaller macromolecules that the cells can process for energy. In order for the cells to utilize the nutrients, oxygen from the respiratory system is needed. The respiratory system takes in oxygen from the air and helps to expel the carbon dioxide we generate.

• Chapter 15, “Nutrition: You Are What You Eat.” In this chapter, you will learn how the digestive system breaks down these molecules into usable units of energy. “You are what you eat,” is a popular phrase. But it is true?
• Chapter 16, “The Digestive System.” In this chapter, you will learn more about the process of digestion. We eat three to five pounds of food each day to provide us with energy.

Assessment Instructions

OVERVIEW

In this lab, you will be looking at food labels. Food labels provide important information about the nutrient content of packaged food. You will analyze a food label from your own kitchen and discuss whether the food item is a healthy choice. Try to find a food item you eat often to see whether or not this is a healthy choice.

• Digestion Lab.

INSTRUCTIONS

For this assessment, you will complete a series of responses within the lab, complete an assessment at the end of the lab, and write a brief summary of your conclusion about the lab. To complete this assessment:

1. Fill out the items requested in the lab.
2. Complete the assessment at the end of the lab.
3. Save a pdf of your responses and download it to your computer. You will have an option to download a pdf within the lab.
4. Write a one-paragraph summary detailing new knowledge acquired in the lab.
5. Attach both documents when submitting the assessment.

Make sure that you read the Homework: Digestion Lab Scoring Guide prior to submitting your assessments to ensure you have met all of the expectations for this assessment.It is recommended that you review the scoring guide prior to completing the la as most work will be completed within the lab.
