Bio 9D: Wednesday, 12.15.10Title: Circulatory System Homework: Finish Circ. System worksheet if

you don’t 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

QuestionsInstructions 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.

Circulates (moves) blood around the body in order to…

Transport O2 and nutrients to all cells Transport CO2 and other wastes away

from cells Link to Respiratory System:

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!

Review the Do Now:Purpose of the Circulatory System

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

vesselsObjectives 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

Red Blood Cells Carry Oxygen Contain Hemoglobin (protein

that gets bright red when carrying O2)

White Blood Cells Fight Infection/Disease

Platelets Proteins that clot blood (clump it

up & form a scab if injured) Plasma

The liquid that blood cells & platelets float in

90% water 10% other stuff: glucose,

enzymes, hormones, etc.

Blood has 4 components:

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

Blood:Blood inside Blood Vessels!

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

Arteries: Function:

Bring blood away from the heart to the body

Structure: Large tubes Thick, muscular,

stretchy walls to withstand pressure from pumping heart

Structures of the Circulatory System: Blood Vessels

Objectives for Class: Explain why we need blood Explain the key differences in structure and function between arteries, capillaries, and veins

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

Structures of the Circulatory System: Blood Vessels

Objectives for Class: Explain why we need blood Explain the key differences in structure and function between arteries, capillaries, and veins

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

Structures of the Circulatory System: Blood Vessels

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

QuestionsPlease pass your index cards forwardInstructions: 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.

Bio 9D: Thursday, 12.16.10Title: 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)

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

Bio 9D: Friday, 12.17.10Title: Heart Dissection Lab

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, gogglesPartners: 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 roles3. Start the procedure by reading and following each

step.
