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
Today’s Agenda


Notes/Discussion of Circ. System, Blood, & Blood Vessels
Worksheet – Circulatory System Review Questions
Instructions for Notes: On each slide:
1. Silently write down the notes or check/add to your Do Now and HW
notes as your student-teacher explains the slide
2. Your student-teacher will ask for clarifying questions. Raise your
hand if you have one.
3. 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.
4. Write any un-answered questions on your index card for Ms. Dickson
to answer when she gets back.
Review the Do Now:
Purpose of the Circulatory System
Circulates (moves) blood around the body in
order to…



Link to Respiratory System:



Transport O2 and nutrients to all cells
Transport CO2 and other wastes away from
cells
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
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
Blood has 4 components:

Red Blood Cells



White Blood Cells


Fight Infection/Disease
Platelets


Carry Oxygen
Contain Hemoglobin (protein that
gets bright red when carrying O2)
Proteins that clot blood (clump it up
& form a scab if injured)
Plasma



White Blood Cell w/
Red Blood Cells
The liquid that blood cells &
platelets float in
90% water
10% other stuff: glucose,
enzymes, hormones, etc.
Objectives for Class:
 Explain why we need blood
 Explain the key differences in structure and function between arteries, capillaries, and veins
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
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
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
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
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

Title: 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!)
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
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
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-rich to O2-poor?
… in the CAPILLARIES
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)
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
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
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!
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:
1.
Review the pre-lab questions and make sure everyone has
completed them.
2.
Turn to page 3 and assign roles
3.
Start the procedure by reading and following each step.
