2. Circulatory System PHA Biology 9 Moretti & Dickson

3. Purpose of the Circulatory System • Transport O2 and nutrients to the different cells of the body • Remove CO2 and other waste materials from the bloodstream • Link to CELL RESPIRATION: • Cells need to get the Oxygen from the lungs to cell respiration to produce ATP • Carbon Dioxide produced from cell respiration needs to get to the lungs to be exhaled through Respiratory System (gas exchange). • Objectives for Class: • Describe the major structures and functions of all organs in the Circulatory system • Explainhow the circulatory system and respiratory system work together to deliver oxygen and remove CO2 from body

4. Structures of the Circulatory System: Heart • Almost entirely muscle. • Two pumps: • Right side: pumps blood to Lungs • Left side: pumps blood to Body • Atria:upper chambers/ receive blood • Ventricles:lower chambers/ pump blood to body • Objectives for Class: • Describe the major structures and functions of all organs in the Circulatory system • Explainhow the circulatory system and respiratory system work together to deliver oxygen and remove CO2 from body

5. Structures of the Circulatory System: Blood Vessels • Arteries: • Function • Bring blood away from the heart to the body (highway) • Most have strong walls to handle high blood flow/ pressure • Structure: • Range in size from very large to quite small • Walls are lined with smooth muscle & elastic tissue • Objectives for Class: • Describe the major structures and functions of all organs in the Circulatory system • Explainhow the circulatory system and respiratory system work together to deliver oxygen and remove CO2 from body

6. Structures of the Circulatory System: Blood Vessels • Capillaries: • Function: • Exchange materials from the blood with other body tissues • Deliver nutrients and oxygen to body tissues • Absorb waste products (like CO2) from body tissues • Structure: • Smallest type of blood vessels (side streets) • Thin walls = easy for materials to move across wall • Thickness = big enough for 1red blood cell to fit single file • Objectives for Class: • Describe the major structures and functions of all organs in the Circulatory system • Explainhow the circulatory system and respiratory system work together to deliver oxygen and remove CO2 from body

7. Structures of the Circulatory System: Blood Vessels • Veins: • Function • Bring blood toward the heart after it has passed through the capillaries. (highway) • Most have strong walls • Blood moves in a one-way loop back to heart • Structure • One way valve system that keeps blood flowing towards the heart • Range in size from very large to quite small • Walls are lined with smooth muscle & elastic tissue • Objectives for Class: • Describe the major structures and functions of all organs in the Circulatory system • Explainhow the circulatory system and respiratory system work together to deliver oxygen and remove CO2 from body

14. Function of the Circulatory System: Circulation • Left Side of the Heart: • Blood is pumped from heart to the rest of the bodyby arteries. • Full of Oxygen • Blood drops off oxygenfor other cells to do cell respiration. Picks up carbon dioxide. • Blood returns to Right Side of Heart by veins • No Oxygen – full of CO2 • Objectives for Class: • Describe the major structures and functions of all organs in the Circulatory system • Explainhow the circulatory system and respiratory system work together to deliver oxygen and remove CO2 from body

21. Heart Dissection – Materials • Aprons, goggles & gloves • Dissecting tray • Extra beaker – for dumping excess liquid • Scalpel – caution, these are sharp! Never cut towards fingers! • Scissors – often these are better for cutting than the scalpel • Adult pig heart

22. Heart Dissection - Rules • Respect for the animals that donated these hearts • Safety • Raw meat… keep hands away from mouth, wash hands after. • Scalpels are sharp! • Patience – this might be confusing. That’s OK! You can learn a lot even if you can’t figure out all the parts. • Zero tolerance for fooling around, horseplay, etc. • You WILL be asked to leave

25. Bio 9B: Monday, 12.20.10 Title: Graphic Novel: The Path of the Oxygen Molecule • Homework: • Study for the Cell Membranes part of the test by: • Completing quiz corrections on separate paper (for multiple choice – write the correct answer and WHY) • Answering the Cell Membrane study guide • Do Now: • What is the most memorable aspect of the heart dissection? • What aspects of circulation still confuse you? • Today’s Objectives: • In detail explain the pathway of oxygen through the respiratory and circulatory systems. • Describe how the structures of the respiratory and circulatory systems work together to move oxygen and carbon dioxide through the body.

26. Graphic Novel: The Path of the Oxygen Molecule • Part I: You will work in a small group with a graphic that is one piece of the story. In this group, you have two tasks: • In writing, describe the path that the oxygen molecule takes and what happens to it. Be sure to highlight key organs that it passes through, and key processes that it undergoes. For example, any time that the molecule diffuses through a cell membrane, mention that! • Label the key structures in your diagram and draw your oxygen molecule traveling through the diagram in your graphic. You can just do a simple “O2”, or you can get creative and come up with a tiny avatar representing the oxygen. Either way, draw it at each step along the way, with arrows showing how it travels.

27. Bio 9B: Tuesday, 12.21.10 Title: Graphic Novel: The Path of the Oxygen Molecule – Day 2 • Homework: • Complete Study Guide • Do Now: • Announcements, then get into groups and Begin Work! • Today’s Objectives: • In detail explain the pathway of oxygen through the respiratory and circulatory systems. • Describe how the structures of the respiratory and circulatory systems work together to move oxygen and carbon dioxide through the body.

28. Graphic Novel: The Path of the Oxygen Molecule • Part II (Days 2 and 3) – You will then switch into a different group comprised of people who each wrote a different part of the story, with a different picture. This is where you will complete the entire graphic novel, in the template that your teacher provides. Your tasks in your new groups are: • Figure out what order your diagrams and story segments go in. Arrange them in order on your table,. • Start with the person with the first part of the story. That person should: • Read your story out loud, sentence by sentence. Other group members should write down this story as you read. • Explain your diagram and how the oxygen molecule moves through it. Other group members must draw their own version of this diagram, and the oxygen molecule, into their graphic novel. • The next person in the sequence should then read out loud their part of the story. Before writing it down, the group should work together to construct a transition sentence that links the first part of the story to the second part. • Then, follow steps (a) and (b) above to have everyone in the group record the story and the diagram. • Continue this process for all 6 members of your group,
