Review the functions of the respiratory systems and digestive system in one little package!
Students compare the alveoli of the lungs to the villi of the digestive system, which nicely highlights their respective systems and functions and the fact that they both utilize lots of surface area. Use this towards the end of a Human Body Unit when reviewing for a test.
This is a HALF PAGE worksheet, so you make half the copies and cut in half. This worksheet may be little but it's a favorite! This is a Word document, so it is a breeze to edit to better fit your needs or to modify for particular students.
