cells
Blood takes O2 from lungs and brings it to
cells

Important New Year’s Announcements
for 9th Grade Biology!
• Hall passes – they’re back! Find them in the
corner by the clock. Use them!
• New policy for Office Hours – You need to sign
up to attend Biology Office Hours on Tuesdays or
Thursdays.
– Sign up each week for the day(s) you want to come
– Write down the assignment you need help on
(examples: lab report revisions, quiz retake, studying
for a quiz, reviewing a specific topic)
– The Bio Lab will no longer be freely available for
students to sit and do their HW. Go to detention or
the learning commons.


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.

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
Short Break…

Staple your notes page into your notebook!
Notes in your notebook:
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
Bio 9B: Friday, 1/6/12
Title: Circulation
Homework: Finish the heart dissection pre-lab if you don’t finish in
class.
Silent Do Now – in your notebook w/ date and title
1.
Why does blood go to the lungs?
2.
Why does blood go to the rest of the body?
Today’s Objectives: You will be able to…


Explain the purpose of the pulmonary and systemic circuits
Make predictions about the structures you’ll see in a real heart
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

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.
