What is the Circulatory System? ? The Circulatory System is how good and bad materials travel through our bodies. Answer:
The Circulatory System moves food and oxygen to our cells. The Circulatory System removes carbon dioxide and waste from our bodies. + &
Cells use food and oxygen to make energy, which keeps us alive . http://www.biology.arizona.edu/cell_bio/activities/cell_cycle/cell_cycle.html

Blood travels through tubes called blood vessels http://www.besttreatments.co.uk/btuk/images/circluation_animation.gif <ul><li>There are 3 types of </li></ul><ul><li>blood vessels: </li></ul><ul><li>Arteries ( red ) </li></ul><ul><li>Veins ( blue ) </li></ul><ul><li>Capillaries </li></ul>
The inside of our veins & arteries looks something like this! See all the red and white blood cells? http://www.kentleech.com/cells.jpg Stay tuned for more about veins & arteries…
When we breathe in, our lungs take In OXYGEN. The oxygen passes into our blood through our blood vessels. Stille, Darlene R. , pg 16
BLOOD, with fresh oxygen is pushed through our blood vessels by a muscular pump the size of our fist known as the HEART http://www.mnartists.org/uploads/users/user_555/1296dd906705e25ad83098f7a62258d7/1296dd906705e25ad83098f7a62258d7.jpg

Let’s take a look at the Heart at work See the difference in the HEART rate when we are resting, in school, or playing sports?
When we do not exercise or eat properly , we damage our heart.
Fatty foods can make the inside of our Blood vessels narrow This blocks blood flow If blood cannot reach the heart, the HEART muscle begins to die This causes a HEART ATTACK http://www.healthexpo.org/Bluit%20Cover.jpg Stille, Darlene R. pg 31
Do You REMEMBER What Veins & Arteries Are? BLOOD VESSELS
VEINS are blood vessels that carry used blood back to the heart. The heart sends the blood back to the lungs to pick up more oxygen. What color are veins? It’s a Fact! Your Body , p.g. 12
The Aorta http://www.mayoclinic.org/marfan/images/symptom2.jpg The AORTA within the heart is the largest ARTERY The Aorta takes blood with oxygen and delivers it to every part of our body. Arteries are blood vessels that carry blood AWAY from the heart. It’s a Fact! Your Body pg 12
Capillaries Are the smallest blood vessels They branch off from every Vein and Artery . http://www.healingdaily.com/detoxification-diet/capillaries.jpg It’s a Fact! Your Body p.g.12
Let’s Review some of the important Facts we’ve learned about the Circulatory System http://www.besttreatments.co.uk/btuk/images/circluation_animation.gif
How does our body transport food, Oxygen, carbon dioxide and waste? Answer: through a fluid called BLOOD
Blood travels through our bodies Through BLOOD VESSELS What are the 3 types of BLOOD VESSELS? VEINS ARTERIES & C A P I L L A R I E S
How many chambers does the HEART have? 4 Right Atrium, Right Ventricle Left Atrium & Left Ventricle Chambers http://www.mnartists.org/uploads/users/user_555/1296dd906705e25ad83098f7a62258d7/1296dd906705e25ad83098f7a62258d7.jpg
Which blood vessels carry used blood BACK to the heart? VEINS Which blood vessels carry blood AWAY from the heart to other parts of our bodies? ARTERIES
What is the name of the LARGEST ARTERY? Hint: It is located within the HEART. The AORTA
What can happen if we do not eat HEALTHY or EXERCISE ?
Fatty Foods can block blood flow If BLOOD cannot reach the HEART… This can cause a HEART ATTACK YIKES!
So Remember: Take Good care of your HEART! Eat Healthy… Exercise… And get plenty of sleep!
ENCORE?! Okay! Here’s a fact that will AMAZE your friends… “ Did you know that if all your ARTERIES , VEINS , & CAPILLARIES Were joined together end to end They would stretch more than 62,000 miles or 2 and a half times Around the EARTH???!!!” It’s a Fact! Your Body p.g. 12
How fast does YOUR heart beat per minute? 30 beats 70 beats 70 beats 165 beats 530 beats 750 beats 1000 beats Capeci, Anne. The Magic School Bus Has a Heart, p.g. 29.
