• The heart is the main organ of the circulatory system.
• It consists of:
o 4 Chambers
o In/Out Blood Vessels
o Thick Walls
The job of the heart is to:
Why do we need oxygen?
The Circulatory System consists of the heart, blood vessels, & blood.
Overview of Blood Components
Plasma & Nutrients
Red Blood Cells
White Blood Cells
* Made up of 90% water and nutrients
Fight and eat germs (infections)
Work together to form blood clots
What is a Heart Attack?
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
Causes of a Heart Attack
Low Blood Pressure
High Blood Pressure
Blood Clot & High Cholesterol
Prevention of Heart Attack
Treatments of Heart Attack
Immediate Treatment of Heart Attack:
CPR & AED
to transport materials throughout the body (nutrients, oxygen, wastes)
Pump OXYGENATED blood throughout the body.
* The oxygen we breathe in goes to our lungs.
Where is that oxygen coming from?
* To give our cells energy.
The purpose of blood vessels is to...
Transport the blood itself to all of the cells in the body.
* Arteries: Travel ________________ the heart.
* Veins: Travel ____________ the heart.
* Smallest blood vessels
* Exchange oxygen and nutrients with __________.
The purpose blood is to deliver/supply nutrients, oxygen and waste products throughout the body.
Blood also carries cells which have their own functions.
* White Blood Cells: Germ Fighters
* Red Blood Cells: Carry Oxygen
from heart carrying oxygen
exchange nutrients & oxygen with body cells
the heart carrying wastes (CO2)
* All tubes!
* All carrying blood (RBCs, WBCs, & platelets)
* All connected!
Circulatory System Review & Respiratory!
What to do in a cardiac emergency!
measure your own blood pressure...but... you
measure your heart rate (per minute)!
a rhythmical throbbing of the arteries as blood is propelled through them, typically as felt in the wrists or neck.
First, find which pulse is easier for you to locate.
if you count 25 beats, 25 x 4 = 100 beats per minute.
Take this number and multiply by 4 to find your heart rate in beats per minute.
Second, Count the number of beats (pulses) for 15 seconds.
Finding Pulse / Heart Rate
Circulatory System & Heart
Normal Heart Rate
12 - 16 breaths/per min
At rest, a breathing rate can be...
The best way to measure breathing rate is to count breaths (chest rising) in a full minute!
c. BREATHING RATE CHECKER
b. TIMER & RECORDER
a. RUNNER & PULSE CHECKER
1. Form a group of 3
2. Assign the following roles:
It puts the "stream" in bloodstream!
Carry Oxygen from lungs to all of the cells
Made in Bone Marrow
Contain Protein "Hemoglobin"
blood flow between heart and lungs
blood flow AWAY from heart and TO LUNGS
blood from TO heart FROM LUNGS
blood flow between heart and BODY
Give a heart transplant a try!
Read this page in your notes about the circulatory system and fill in the crossword puzzle and graphic organizer based on this information.
In your notes.
To/From your sub.
Tuesday, October 18th Agenda
1. Finish/turn in crossword & graphic organizer.
Use this prezi until you see "STOP" to fill in the next page of your notes on "What is in your blood?"
3. Answer the exit ticket and reading questions about components of your blood.
October 26, 2016 Agenda
First, students will watch a few short videos about the heart.
Then, students will fill in their notes on the structure of the heart until you see the word STOP!
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.
Google Form on Google Classroom!!!
(from lungs to heart)
Get a blue and red colored pencil/marker/crayon!
Eating greasy and fatty foods can cause cholesterol to build up in blood vessels!
In addition, if blood can not flow to/from the heart, then a heart attack can occur.
This constricts blood flow to parts of the body. This can cause the heart to work harder.
Also illustrated here and here!
Can a "broken heart" be repaired?
It can be repaired.
* Bypass surgery
It can be replaced,
* Heart Transplant
* Low Cholesterol Diet
* Low Sodium Diet
away from heart
oxygen and other nutrients are delivered to body cells
travels TO heart
