2. 29.1 How Organ Systems Communicate 1)Name a few ways that you communicate. Speech Body language Touch Written language 2)What do you think accounts for the different colors in the MRI scan? Brain scans are used to study the structure of the brain and to identify brain abnormalities. Scans can also be used to study brain activity associated with thinking, which occurs in the front part of the brain.

3. 29.1 How Organ Systems Communicate Points to Ponder With your table, please discuss what parts of your body or systems of your body must work together to get you to the top of this wall of ice

4. 29.1 How Organ Systems Communicate The Human Body Climbing a wall of ice requires careful interaction among all parts of the body –Muscles work together to coordinate the climber’s movements –Heart and lungs need to work together to provide energy for the climb In this unit, Physiology, we will learn how different parts of the body work together to keep the body functioning properly

6. 29.1 How Organ Systems Communicate Magenta Opal Aquamarine Violet Cyan Taupe Ebony Teal Memorize this list of colors: See what you can remember and write them down on the top of pg. 33

7. 29.1 How Organ Systems Communicate Which list were you able to recall better? Why do you think?

8. 29.1 How Organ Systems Communicate Which list were you able to recall better? –Probably the 1st Why do you think? –Because the words on the first list were more familiar.

9. 29.1 How Organ Systems Communicate Learning involves memory. We remember things because our brain creates pathways to store information. If a pathway is used more often, the information is more easily remembered. Why was the first list easier to remember? We use or see those colors more often.

10. 29.1 How Organ Systems Communicate Standard 9.b Students know how the nervous system mediates communication between different parts of the body and the body’s interactions with the environment.

11. 29.1 How Organ Systems Communicate KEY CONCEPT The nervous system and the endocrine system provide the means by which organ systems communicate.

12. 29.1 How Organ Systems Communicate Take a minute to think about these questions with your table: How do you know you are hungry? How do you know you are hot? Do you tell yourself to sweat? Do you tell yourself to grow? Do you actively need to tell yourself to digest your food? Do you decide what temperature your body is?

13. 29.1 How Organ Systems Communicate Your brain lets you think and move. It controls digestion, heart rate, and body temperature. Your brain does these things with help from the endocrine system and the rest of the nervous system.

14. 29.1 How Organ Systems Communicate A stimulus causes a response –Anything that triggers a change in an organism –Responses can be chemical, cellular, or behavioral Both of these systems let you respond to a stimulus:
