2. Mr. Jobe Anatomy and Physiology

3.  Anatomy = Structure  WHERE the body parts are  From the Greek ana meaning “apart” and tomy meaning “to cut”  Organisms are usually cut apart to see their anatomy  Physiology = Function  WHAT the body parts do  From the Greek physio meaning “nature” and ology meaning “the study of”  Studying of the “nature” of an organ

6. The Digestive System  Anatomy:  Mouth, esophagus, stomach, intestines, rectum  Physiology:  Break down the food we eat into useful materials  Get rid of the waste

7.  Read more about each system:  Skeletal System (pg. 4)  Nervous System (pg. 4)  Digestive System (pg. 7)  When you have finished reading, work on the KWL worksheet  Write about what you…  Know  Want to know  Learned Reading Assignment

8. Classwork  Organ system diagram  Draw the three systems we covered today on the handout  Use a different color for each system  Label the important structures (anatomy)  Say what they do (physiology)
