Bio 9C: Wednesday, 12.15.10Title: Circulatory System: Structures & Functions

PHA Biology 9Moretti & 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

Today’s Objectives: Explore the anatomy of a real heart! Compare what you know about the heart to the real thing.

Bio 9C: 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

Bio 9C: 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.

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.

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?
