Homework: *Do this on a separate sheet of paper or type it! Continue the essay you began by writing on Wednesday. For the

continuation of the story, follow the molecule of oxygen from the alveoli in the lungs through the circulatory system. The story should end with a molecule of oxygen being “dropped off” at the mitochondrion of a cell in the body for cell respiration. Your story should use and make connections between the following vocabulary: Capillary, Vein, Heart, & Artery

Do Now: Based on last night’s reading, what is the function of the

circulatory system? How does this system relate to cell respiration?

Today’s Objectives: 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

Bio 9C: Monday, 12.14.09Title: Circulatory System: Structures & Functions

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

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 9C: Wednesday, 12.16.09Title: 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: *Do this on a separate sheet of paper or type it! Revise the essay you began by writing on Tuesday and “completed”

for today. For the continuation of the story, follow the molecule of oxygen from the alveoli in the lungs through the circulatory system. The story should end with a molecule of oxygen being “dropped off” at the mitochondrion of a cell in the body for cell respiration. Your story should use and make connections between the following vocabulary: Capillary, Vein, Heart, & Artery

Do Now: What are the major differences between arteries and veins?

Answer: Arteries bring blood away from the heart; Veins bring blood to the heart (remember A = AWAY (arteries); Vein – “in” the heart)

Today’s Objectives: 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

Bio 9C: Thursday, 12.17.09Title: Circulatory System: Structures & Functions

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

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

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: Blood

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 Oxygen

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: Circulation

Left Side of the Heart: Blood is pumped from

heart to the rest of the body by arteries.

Full of Oxygen

Blood drops off oxygen for other cells to do cell respiration. Picks up carbon dioxide.

Blood returns to Right Side of Heart by veins No Oxygen – full of

CO2

Studying for Wednesday’s Test (Review Sheet on back of this weeks assignment sheet – also on the blog)

Hold onto the Oxygen Stories for now… I will collect them at the end of class.

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 9C: Friday, 12.18.09Title: The movement of Oxygen through the body

Circulatory System Activity: Roadmaps and the Circulatory System

The Task: Examine maps from different cities, towns, and countries. Identify how the transportation systems have been created to move goods and services from place to place. Describe how this is similar to the human circulatory system Option 1: Group AnalysisEvery person in the group needs to have the following in their notebooks: What are the maps your group examined? Imagine you needed to deliver a package from the outskirts of the city to the downtown area. On one of the maps, trace a path you would take to do so. Think about how these transport systems have been created to move things around based on road sizes, direction of traffic, density of people, etc… How is our internal “transportation system” similar and different than our actual transportation system?  Option 2: Group Activity One product per group:As a group, develop a song, rap, poem, or short story to describe how goods and services move throughout the body. As a group, present this to the class. The more creative the better!
