How do the digestive and circulatory systems work together to get nutrients (food) to the cells?

6C(6-8)#3: To burn food for the release of energy stored in it, oxygen must be supplied to the cells, and carbon dioxide removed . Lungs take in oxygen for the combustion of food and they eliminate the carbon dioxide. The urinary system disposes of dissolved waste molecules, the intestinal tract removes solid wastes, and the skin and lungs rid the body of heat energy. The circulatory system moves all these substances to or from cells where they are needed or produced, responding to changing demands.

6C(6-8)#2: For the body to use food for energy and building materials, the food must first be digested into molecules that are absorbed and transported to cells.

NSES (5-8): The human organism has systems for digestion, respiration, reproduction, circulation, excretion, movement, control and coordination, and for protection from disease.   The systems interact with one another.

Getting Started - Journal Prompt: How does food get small enough for the cells to use? This will give students the opportunity to share what they know or do not know about the breakdown of food.

Science Notebook Page A - What happens in the Digestive System? Breaking Down the Food (page 163)

Science Notebook Page B - Student conclusions about what happened to the starch (page 165)

Refer back to How My Body Works chart to add any new questions or statements

• Are students able to identify that food is broken down chemically as well as mechanically?
• Do students understand that both chemical and mechanical breakdown occur throughout the digestive system?
• Do students understand the role of enzymes in chemical digestion?
