- Slide 1
- WARM UP: Get a Warm Up from the front stool. Read the article.
Highlight or underline important points. Answer the questions on
the back.
- Slide 2
- BLOOD
- Slide 3
- THE PURPOSE OF BLOOD IS: Move oxygen throughout the body Carry
waste to the kidneys Fight infections and heal wounds Carry
nutrients from the digestive system throughout the body
- Slide 4
- WHAT MAKES UP BLOOD? 55% = Plasma Transports red and white
blood cells and platelets Is made up of 90% water 43% = red blood
cells Carry oxygen and carbon dioxide 2% = white blood cells Fight
infection Platelets = large pieces of cells that help clot
blood
- Slide 5
- WE ALL HAVE RED AND BLUE BLOOD! Blood that is BLUE is
oxygen-poor blood. Its oxygen has been used up and it is headed to
the lungs to get more oxygen Blood that is RED is oxygen-rich
blood. It has come from the lungs where it received oxygen and is
ready to go to other parts of the body BUT WHY???
- Slide 6
- HOW DOES THE HEART WORK? The structure of the heart allows
oxygen-rich blood to remain separate from oxygen-poor blood: they
are going to two different places!
- Slide 7
- WHAT MOVES YOUR BLOOD AROUND? Blood travels through blood
vessels Arteries: Carrie blood full of oxygen and nutrients away
from the heart Veins: Carry blood full of carbon dioxide into the
heart
- Slide 8
- Arteries carry blood AWAY from the heart Veins carry blood TO
the heart
- Slide 9
- WHAT MOVES YOUR BLOOD AROUND? Capillaries: Little blood vessels
that carry blood between arteries and veins
- Slide 10
- WELCOME TO THE CIRCULATORY SYSTEM
- Slide 11
- CIRCLE CYCLE The circulatory system is the CYCLE that your
blood takes around your body
- Slide 12
- Circulatory System Delivers oxygen and other nutrients to the
bodys cells
- Slide 13
- TWO FUNCTIONS OF THE CIRCULATORY SYSTEM TO PUMP OXYGEN-RICH
BLOOD TO THE CELLS TO REMOVE CARBON DIOXIDE FROM THE CELLS

- HEARTVEINS ARTERIES
- Slide 16
- HEARTVEINS ARTERIES -Pump made of cardiac muscle -Pumps
oxygen-rich blood from the lungs to the rest of the body -Pumps
oxygen-poor blood from the rest of the body to the lungs -Tubes
that carry blood -carry oxygen- poor blood FROM all parts of the
body TO the heart -Tubes that carry blood -carry oxygen- rich blood
FROM the lungs TO all parts of the body

- VEINS ARTERIES
- Slide 20
- What are the similarities and differences between
- Slide 21
- ARTERIES TAKE BLOOD AWAY FROM THE HEART PUMPS OXYGEN-RICH BLOOD
TO THE LUNGS TO THE REST OF THE BODY
- Slide 22
- VEINS TAKE BLOOD TO THE HEART DELIVERS OXYGEN- POOR BLOOD FROM
THE BODY TO THE HEART
- Slide 23
- BOTH: Found all over the body Pumped by the heart Carry blood
to and from the lungs
- Slide 24
- ARTERIES START AT THE HEART
- Slide 25

- BUT WHAT ABOUT THE HEART???

- WARM UP: Get a sheet from the front DESK. You do not need to
fill anything in. We will start with Heart notes today!
- Slide 29
- THE HEART: The heart is the central organ of the circulatory
system. Its function is to pump blood around the body Every time
the heart beats, it pushes blood through the blood vessels of the
circulatory system.
- Slide 30
- WHAT DO YOU NOTICE ABOUT THIS DIAGRAM THAT SEEMS ODD?
- Slide 31
- WHY IS THE LEFT SIDE OF THE HEART LABELED AS THE RIGHT AND VICE
VERSA???
- Slide 32
- THE PARTS OF THE HEART: The heart is separated into two sides
right and left The two halves are separated by the septum. Septum =
a wall of tissue that separates the sides of the heart and keeps
the oxygen-rich blood from mixing with the oxygen-poor blood Each
side of the heart is also separated into two compartments. Top of
each side = atrium Receives blood that comes into the heart Lower
chamber of each side= ventricle pumps blood out of the heart Valve
= flap of tissue that separates the atrium from the ventricle and
prevents blood from flowing backwards and also between ventricles
and blood vessels

- The human heart is about the size of your fist!
- Slide 36
- Slide 37
- Slide 38
- FAST FACTS! The average heartbeat is 72 times per minute. In
the course of one day it beats over 100,000 times. In one year the
heart beats almost 38 million times, and by the time you are 70
years old, on average, it's made it to 2.5 billion beats.
