PHA Biology 9
Moretti & Dickson
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).
Purpose of the Circulatory System
Objectives for Class: Describe the major structures and functions of all organs in the Circulatory system Explain how the circulatory system and respiratory system work together to deliver oxygen and remove CO2 from body
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 Explain how the circulatory system and respiratory system work together to deliver oxygen and remove CO2 from body
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
Structures of the Circulatory System: Blood Vessels
Objectives for Class: Describe the major structures and functions of all organs in the Circulatory system Explain how the circulatory system and respiratory system work together to deliver oxygen and remove CO2 from body
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 fileObjectives for Class:
Describe the major structures and functions of all organs in the Circulatory system Explain how the circulatory system and respiratory system work together to deliver oxygen and remove CO2 from body
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

Blood: Components
Red Blood Cells Contain Hemoglobin Carry Oxygen
White Blood Cells Fight Infection
Platelets Proteins that clot blood
Plasma The fluid all of these float in 90% water 10% other stuff: salts,
gases, enzymes, hormones, etc.
Structures of the Circulatory System: Blood
White Blood Cell w/ Red Blood Cells
Start on Right Side of the Heart: Blood is pumped
from heart to the lungs by arteries.
No Oxygen – full of CO2
Blood drops off carbon dioxide. Gets oxygen.
Oxygen rich blood returns to left side of heart by veins Full of OxygenObjectives for Class:

Homework: Tonight: Heart Dissection Reflection Paragraph – on
separate paper
Do Now: Get an apron and gloves Sit with your lab group Clear tables of everything else Complete the Heart Dissection Pre-Lab
Today’s Objectives: Explore the anatomy of a real heart! Compare what you know about the heart to the real thing.
Bio 9B: Thursday, 12.16.10Title: Heart Dissection Lab
Function of the Circulatory System: Circulation
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
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

Heart Dissection: Reference Materials
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.
Bio 9B: Monday, 12.20.10Title: Graphic Novel: The Path of the Oxygen Molecule
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.
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.
Bio 9B: Tuesday, 12.21.10Title: Graphic Novel: The Path of the Oxygen Molecule – Day 2
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,
Internal Transport Review Guide
Cell Membranes What is the function of the cell
membrane? What is its structure?
Significance of the lipid bilayer Selective Permeability?
What are the different ways substances move across cell boundaries? How are they different? Osmosis Diffusion Active Transport
Which of these is used for Gas Exchange
Respiratory System What are the major structures of
the Respiratory System? What is the function of the
Respiratory System? How does breathing happen
(physically)… think: “balloon in the bottle”
Circulatory System What are the major Structures of the
circulatory system? Heart, arteries, capillaries, and
veins How does their structure fit their
function? How do these structures move blood
through our bodies? How are the respiratory and circulatory
systems linked to each other? What is Gas Exchange? Where does it happen? Why is it
important? How are carbon dioxide and oxygen
exchanged between the respiratory and the circulatory systems?
Big Important Questions: How do the circulatory and
respiratory systems relate to cell respiration?
Explain what happens to a molecule of oxygen as it moves from the air around you and travels throughout your body. Your explanation should also describe where carbon dioxide comes from and how it is exhaled from the body.
Why do we breathe? How do we breathe? How do things move through our bodies?
Bio 9B: Wednesday, 12.22.10Title: Internal Transport Test
Homework: Enjoy your break! (…and think about how your digestive
system works while you eat, why you breathe, how you breathe, and how your body transports things throughout your body… you’ve learned a lot so far!)
Do Now: Take Everything off of your desk, zip up your
bags, and get ready to take the test… you will need the whole time!
Today’s Objectives: Demonstrate your understanding of how the
structures of the respiratory and circulatory systems work together to move oxygen and carbon dioxide through the body.
