- 3. Stomach - 4 -6 hours (acids and Enzymes)
- 4. Small Intestine (27 feet)- Nutrients are absorbed (live, bile, gall blatter, pankreas
- 5. Large Intestine (colon) - Water is absorbed, 4 to 6 feet,
- 6 Rectum
- 7 Anus
- 8. Feces
What is one example how food changes physically and chemically in the digestive system?

- Blood Vessels - Carries blood throughout the body
What is the route of Red Blood Cells through the heart, lungs, and vessels to circulate oxygen to boody cells and rid the body of waste?
- 1) Born in bone marrow
- 2) Goes to heart
- 3) Heart pumps to lungs to get oxygen
- 4) Travels through vessels
- 5) Back to heart through the spleen and liver where it filters the waste.
