Red Blood Cells

• Carry Oxygen from lungs to all of the cells

• Made in Bone Marrow

First, students will watch a few short videos about the heart.

• Contain Protein "Hemoglobin"

White Blood Cells

• Fight and eat germs (infections)

Then, students will fill in their notes on the structure of the heart until you see the word STOP!

STOP

Platelets

• Work together to form blood clots

Then, you will fill in the GOOGLE FORM on google classroom, read the passage, and answer the questions about the structure and function of the heart.

BRAIN POP:

Circulatory System & Heart

Heart (Cont.)

The job of the heart is to:

Pump OXYGENATED blood throughout the body.

lungs

The Heart

• The heart is the main organ of the circulatory system.

• It consists of:

o 4 Chambers

o In/Out Blood Vessels

o Thick Walls

heart

Oxygen

liver

kidneys

Why do we need oxygen?

* To give our cells energy.

Blood Vessels

The purpose of blood vessels is to...

Where is that oxygen coming from?

Transport the blood itself to all of the cells in the body.

arteries

Structure

3 types:

AWAY FROM

veins

* The oxygen we breathe in goes to our lungs.

TOWARDS

capillaries

The Circulatory System consists of the heart, blood vessels, & blood.

* Arteries: Travel ________________ the heart.

* Veins: Travel ____________ the heart.

* Capillaries:

* Smallest blood vessels

* Exchange oxygen and nutrients with __________.

CELLS

The purpose of the circulatory system is...

BLOOD

The purpose blood is to deliver/supply nutrients, oxygen and waste products throughout the body.

Blood also carries cells which have their own functions.

to transport materials throughout the body (nutrients, oxygen, wastes)

10/17 Agenda:

Read this page in your notes about the circulatory system and fill in the crossword puzzle and graphic organizer based on this information.

* Red Blood Cells: Carry Oxygen

* White Blood Cells: Germ Fighters

In your notes.

Blood Vessels

To/From your sub.

Blood Vessels

arteries:

away from heart

(oxygenated blood)

veins:

travels TO heart

(deoxygenated blood)

SMALLEST!

carry blood to the heart carrying wastes (CO2)

carry blood away from heart carrying oxygen

exchange nutrients & oxygen with body cells

* All tubes!

* All connected!

* All carrying blood (RBCs, WBCs, & platelets)

capillaries:

oxygen and other nutrients are delivered to body cells

Circulatory System Review & Respiratory!

Circulatory System

What is a Heart Attack?

Causes of a Heart Attack

Prevention of Heart Attack

Treatments of Heart Attack

• Immediate Treatment of Heart Attack:
• CPR & AED
• Bypass Surgery
• Heart Transplant
• Pacemaker

Exercise

Healthy Diet

* Low Cholesterol Diet

* Low Sodium Diet

No Smoking

Take Aspirin

Less Stress

Low Blood Pressure

High Blood Pressure

Blood Clot & High Cholesterol

Heart Disease

Irregular Beat

* drugs

* murmur

* etc.

A heart attack occurs when the heart stops beating due to...

* Chambers can not contract

* No electrical current

* Too tired

* Blood can not reach heart or lungs

10.31 Agenda

Check out this website!

Follow this Prezi until you see STOP!

WHY?

Fill in the last page of your notes!

Try taking your PULSE!

Radial Artery:

Visit & check out the website at the end!

• Review circulatory system basics.
• Review structure & function of heart.
• Review structure & function of blood vessels.
• Review heart rate and pulse.
• Learn more about blood pressure.

Make sure you take your Google Form!

Open Notes Quiz Tomorrow!

http://lessons.e-learningforkids.org/efk/Courses/Liquid_Animation/Body_Parts/Heart_and_Circulation/heart_object.swf

Can a "broken heart" be repaired?

YES!

What to do in a cardiac emergency!

It can be repaired.

* Bypass surgery

* Pacemaker

You can not measure your own blood pressure...but... you can measure your heart rate (per minute)!

It can be replaced,

* Heart Transplant

Eating greasy and fatty foods can cause cholesterol to build up in blood vessels!

This constricts blood flow to parts of the body. This can cause the heart to work harder.

Carotid Artery:

In addition, if blood can not flow to/from the heart, then a heart attack can occur.

Also illustrated here and here!

Pulse: a rhythmical throbbing of the arteries as blood is propelled through them, typically as felt in the wrists or neck.

Finding Pulse / Heart Rate

Give a heart transplant a try!

Normal Heart Rate

60-100 beats/min

• First, find which pulse is easier for you to locate.

AT REST!

What is blood pressure?

• Second, Count the number of beats (pulses) for 15 seconds.

exit ticket:

77*F

1. Form a group of 3

• Take this number and multiply by 4 to find your heart rate in beats per minute.

Blood Pressure Definition

http://www.abc.net.au/science/lcs/heart.htm

2. Assign the following roles:

a. RUNNER & PULSE CHECKER

For example, if you count 25 beats, 25 x 4 = 100 beats per minute.

Breathing Rate

Narrow blood vessels (from poor diet and smoking) can cause high blood pressure!

http://www.pbs.org/wgbh/nova/eheart/transplantwave.html

b. TIMER & RECORDER

At rest, a breathing rate can be...

12 - 16 breaths/per min

c. BREATHING RATE CHECKER

Measured with a sphygmometer.

The best way to measure breathing rate is to count breaths (chest rising) in a full minute!
