Bio 9D: Wednesday, 12.15.10 Title: Circulatory System

1. Bio 9D: Wednesday, 12.15.10Title: Circulatory System • Homework: Finish Circ. System worksheet if you don’t finish in class. • Silent Do Now (in NB w/ title & date) • Based on last night’s reading, what is the purpose of the circulatory system? • How does the circulatory system connect to the respiratory system? • How does the circulatory system relate to cell respiration? • Today’s Objectives: SWBAT… • Explain the purpose of the circulatory system and why we need blood • Explain the key differences in structure and function between arteries, capillaries, and veins

2. Today’s Agenda • Notes/Discussion of Circ. System, Blood, & Blood Vessels • Worksheet – Circulatory System Review Questions Instructions for Notes: On each slide: • Silently write down the notes or check/add to your Do Now and HW notes as your student-teacher explains the slide • Your student-teacher will ask for clarifying questions. Raise your hand if you have one. • Your student-teacher will ask for 1-2 other questions (not more than 2 per slide). Your student-teacher will allow 1-2 comments only from other students in response to that question. • Write any un-answered questions on your index card for Ms. Dickson to answer when she gets back.

3. Review the Do Now: Purpose of the Circulatory System Circulates (moves) blood around the body in order to… • Transport O2 and nutrients to all cells • Transport CO2 and other wastes away from cells • Link to Respiratory System: • Blood takes O2 from lungs and brings it to cells • Blood takes CO2 from cells and brings it to lungs to be exhaled • Discuss the link to Cell Respiration! • Objectives for Class: • Explain the purpose of the circulatory system and why we need blood • Explain the key differences in structure and function between arteries, capillaries, and veins

4. Structures of the Circulatory System: 3 Main Structures • Blood – mixture that carries oxygen, nutrients, and wastes through the whole body • Blood vessels – tubes that carry blood • Heart – pumps blood through the vessels • Objectives for Class: • Explain the purpose of the circulatory system and why we need blood • Explain the key differences in structure and function between arteries, capillaries, and veins

5. Blood has 4 components: • Red Blood Cells • Carry Oxygen • Contain Hemoglobin (protein that gets bright red when carrying O2) • White Blood Cells • Fight Infection/Disease • Platelets • Proteins that clot blood (clump it up & form a scab if injured) • Plasma • The liquid that blood cells & platelets float in • 90% water • 10% other stuff: glucose, enzymes, hormones, etc. White Blood Cell w/ Red Blood Cells • Objectives for Class: • Explain why we need blood • Explain the key differences in structure and function between arteries, capillaries, and veins

6. Blood inside Blood Vessels! Blood: White Blood Cell w/ Red Blood Cells • Objectives for Class: • Explain why we need blood • Explain the key differences in structure and function between arteries, capillaries, and veins

7. Structures of the Circulatory System: Blood Vessels • Arteries: • Function: • Bring blood away from the heart to the body • Structure: • Large tubes • Thick, muscular, stretchy walls to withstand pressure from pumping heart • Objectives for Class: • Explain why we need blood • Explain the key differences in structure and function between arteries, capillaries, and veins

8. 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: • Very small, branching tubes • Thin walls = easy for materials to diffuse across wall • Objectives for Class: • Explain why we need blood • Explain the key differences in structure and function between arteries, capillaries, and veins

9. Structures of the Circulatory System: Blood Vessels • Veins: • Function • Bring blood back toward the heart after it has passed through the capillaries. • Structure • Large tubes • Walls are thinner than artery walls • One way valves that keep blood flowing towards the heart • Objectives for Class: • Explain why we need blood • Explain the key differences in structure and function between arteries, capillaries, and veins

10. Today’s Agenda • Notes/Discussion of Circ. System, Blood, & Blood Vessels • Worksheet – Circulatory System Review Questions Please pass your index cards forward Instructions: • Work quietly with one partner (not a group) • Use your notes to answer the questions • Ask your student-teacher for permission to work quietly at a back table with your partner (not everyone can do this – 2 people max per large table) HW: Finish this worksheet if you don’t finish in class. • Objectives for Class: • Explain why we need blood • Explain the key differences in structure and function between arteries, capillaries, and veins

12. Bio 9D: Thursday, 12.16.10Title: The Heart & Circulation • Homework: Heart Dissection Pre-Lab Questions 1-7 • Silent Do Now (in NB w/ title & date) • What is the function of the heart? • What do you know about the structure of the heart? • What questions do you have about the heart? • Today’s Objectives: SWBAT… • Explain how the structure of the heart fits its function • Explain the purpose of the pulmonary and systemic circuits • Explain the difference between the left and right sides of the heart • Make predictions about the structure of an actual heart (in preparation for tomorrow’s dissection!)

13. Heart: Structure & Function • Almost entirely muscle. • Two pumps: • Right side: pumps blood to Lungs to get oxygen • Left side: pumps blood to Body to give oxygen to cells Each side has 2 chambers: • Atria:upper chambers/ receive blood • Ventricles:lower chambers/ pump blood out • Objectives for Class: • Explain how the structure of the heart fits its function

14. Circulation: Two Circuits • Pulmonary Circuit – sends blood to lungs to get O2 and drop off CO2 • Pumped from right side of heart (O2-poor blood) • Returns to left side of heart as O2-rich blood

15. Circulation: Two Circuits • Systemic Circuit – sends blood to rest of body to deliver O2 to cells (and pick up CO2 and wastes) • O2-rich blood pumped from left side of heart (through arteries) • O2-poor blood returns to right side of heart (through veins) Where does blood transition from being O2-richto O2-poor? … in the CAPILLARIES

16. Take out the Diagram from yesterday’s worksheet! • We will go over your diagram labels as a class • Then you’ll use colored pencils to show the circuits of the blood: • Color the oxygen-rich blood red or orange • Color the oxygen-poor blood blue or purple • Work for 5 minutes individually on this, then you may talk with your table partner only • If you finish early: start the HW (Heart Dissection Pre-Lab)

17. Bio 9D: Friday, 12.17.10 Title: Heart Dissection Lab • Homework: • Heart Dissection Reflection Paragraph – on separate paper (see end of lab packet for guidelines) • Silent Do Now: (in NB w/ title & date) • Write a specific prediction about what you expect to see in the heart dissection. Your prediction should include some of the specific parts of the heart and what you think they will look like. • What safety rules do you think will be important to follow during today’s dissection? • Today’s Objectives: • Identify the parts of the heart and explain how their structure fits their function

18. Heart Dissection – Materials • Aprons, gloves, goggles • 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 • Forceps and probe • Adult pig heart

19. Heart Dissection - Rules • Respect for the animals that donated these hearts • Safety • Raw meat… keep hands away from mouth, wash hands after. • Scissors 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. Stay at your own table!

20. Heart Dissection: Getting Started… Equipment: • Get gloves, apron, goggles Partners: • Choose a partner (if you don’t want to touch the heart too much, choose a partner who does) • Then sit at a table w/ another pair • 4 people max per table! Getting started: • Review the pre-lab questions and make sure everyone has completed them. • Turn to page 3 and assign roles • Start the procedure by reading and following each step.
