1. Biology Discussion Notes Wednesday 4/29/2015

2. Goals for the Day 1.Be able to list all of the body systems and describe their functions. 2.Be able to describe the structures of each major body system. 3.Be able to describe the major structures of the circulatory & respiratory systems and their functions

3. Question of the Day 4/29 What is the smallest part of the circulatory system, and why does it have to be small? (What is the advantage?)

4. What is the function of the respiratory system? What are the major parts of the respiratory system?

5. Windpipe = ≠ Respiratory System FUNCTION - Gas Exchange The lungs are the site of Gas exchange in the body, and are divided into several smaller pieces:

7. The circulatory system is to a capillary as the respiratory system is to the ____________. Respiratory System FUNCTION - Gas Exchange

8. Alveoli

9. The alveoli is the ____________________part of the respiratory system & connects with the ____________________ part of the circulatory system (the capillaries) allowing for _____________________________________ _______________ (mainly Oxygen and Carbon Dioxide).

10. Where do circulatory & respiratory systems connect? http://www.youtube.com/watch?v=d- f3RL0KiUg http://www.youtube.com/watch?v=d- f3RL0KiUg

11. What other body systems are involved with the respiratory system?

12. When do you think our body knows when to take a breath? How do you control your breathing rate?

13. Your Diaphragm

14. Blood Flow through the heart

17. Major Body Systems – pg 588 Cover-drawing of you and your name! For Each System write the following: Name of system Function Major Structures – DRAW some of the major structures! Circulatory System Function: Delivery of Materials Major Structures:

18. Work Order 4/29 Paper dolls Bird presentation research – Back of bird list – Outline presentation – REMEMBER to CITE SOURCES!!!

19. Can you find the bird?

20. Here’s a hint…

21. It’s an American Bittern!

23. Now that you know what you’re looking for, can you find him in this picture?.........

27. American Bittern Skills Check Friday! Matching Body System & Function Corrections & Retakes through next Tuesday Complete during SRP or before/after school
