Homework Review
What do I need to learn today?
1. What is the circulatory system?
2. Functions of the circulatory
System
3. Parts of the circulatory system
Today’s Goal
 I will know the parts and
function of the circulatory
system.
The
Circulatory
System
!!!!!
 http://kidshealth.org/kid/htbw/CSmo
vie.html?tracking=81347_A
What is it?
The organ system that circulates blood
throughout the body
What does circulate mean?
To move or flow in a circle
Functions of The Circulatory
System
1. Blood Cells carry energy/glucose
(from food person eats) and Oxygen
(that person breathes in) to cells all
over the body
2. Blood takes Carbon Dioxide and other
waste out of cells
We all know that oxygen is the key to
living. It's in the air you breathe, in
your lungs and in your blood. What
you might not know is how oxygen
gets into your blood and how the
blood carries oxygen through your
body.
How does the oxygen get in the
blood?
 You breathe air in through your nose
and mouth. It then makes its way
into your lungs . Oxygen then sticks
to red blood cells as they pass
through the lungs on their path
throughout the body - now the
oxygen is in the blood.
How does energy/glucose from
food get into you blood?
Glucose: is the main sugar found in
blood, taken from the food we eat.
Once almost fully digested, food moves
through the intestines, the nutrients
are absorbed through the walls of the
intestines and put into the blood.
3 Parts of Circulatory System
1. Heart
2. Blood vessels
3. Blood
3 Parts of Circulatory System
1. The heart pumps the blood.
2. The blood vessels are tubes that carry blood.
3. The blood carries oxygen & nutrients to body
cells.
Parts of the Circulatory System
HEART:
Muscular organ that
pumps blood all around
the body.

The Heart
The heart has 4 chambers (sections)
Blood with oxygen in it is shown as red
Blood without oxygen is shown as blue
Red = blood with oxygen in it
Blue= blood without oxygen

D. Take water to cells
2. Name the 1 of the 3 parts of the circulatory
system
Thursday Warm Up
Put homework on desk
1. What are the 2 functions of the
circulatory system?
2. What are the 4 chambers of the
heart called?
2 main functions
1. Carry energy/nutrients and oxygen
to cells all over the body
2. Remove carbon dioxide and other
waste from cells
2. The 4 chambers of the heart
Right atrium
Right Ventricle
Left Atrium
Left Ventricle
Today’s Goal
 I will understand the path blood takes
through the heart and lungs.
Vocabulary Words
 You will use this sheet several days in
a row
 We will not complete the entire thing
today – DO NOT LOOSE IT!
Heart: the main organ of the circulatory system; pumps blood
Atrium: the top part of the heart; receives blood
Ventricle: the bottom part of the heart; Pumps blood out of the
heart
Left side of heart: gets oxygen rich blood from lungs
Right side of heart: gets oxygen poor blood from body
Valve: part of the heart that prevents blood from moving backward
Brainpop Video
Remember Functions of Circulatory
System?
• Blood carries Oxygen to parts of the body
• The lungs work with the heart to do this
• *Because of this the blood flowing through the
heart has a very specific “path”
4 Chambers Layout
• Atrium = the top of the heart
• Ventricle = the bottom of the heart
Memory Tool
A = “top” of the alphabet… and top of heart
V = “bottom” of the alphabet… and bottom of
heart

Blood Flow Steps
Step 1. Blood returns to
your heart from your
body and lungs
Oxygen-poor blood from
your body flows into
your right atrium.
At the same time,
oxygen-rich blood
from your lungs flows
into your left atrium.
• Step 2. Blood flows
from the upper to the
lower chambers.
– Blood flows from your
right atrium into your
right ventricle.
– At the same time,
blood flows from your
left atrium into your left
ventricle.
Step 3.
Blood is pumped back
out to your lungs and
body.
– Your right ventricle
pumps blood out of
your heart to your
lungs, where the
blood's oxygen supply
is replenished.
– At the same time, your
left ventricle pumps
blood — once again
full of oxygen — out of
your heart to your
body.
To body
To lungs
For oxygen

Blood Vessel – tubes that carry blood. 3 kinds = artery,
vein, capillary
Artery – the blood vessel that carries oxygen rich blood
AWAY from the heart (red)
Vein – the blood vessel that carries oxygen
poor blood TOWARD the heart (blue)
Artery = blood AWAY from heart (red)
Vein = blood TOWARD heart (blue)
Capillary – tiny blood vessels that connect
arteries and veins
Aorta
Aorta – the biggest artery, connected to the
top of the heart

Parts of Blood
Blood may seem like just one thing, but
it is really made of four main parts
Hemoglobin: part of red blood cells
Red Blood Cells: (RBC) part of
blood that carries oxygen and
carbon dioxide. (Make blood red)
White Blood Cells: Part of the blood that
fights infection
Plasma: yellowish liquid part of blood that holds the other
parts of blood together (think cytoplasm)
Platelets: Part of the blood that causes
clotting (scabs)
Oxygen: picked up in the lungs by blood, in
red blood cells
Carbon Dioxide: released by red blood cells
in the lungs
