THE CIRCULATORY SYSTEM
The Circulatory System is made up of three main parts: a circulatory fluid,
called_________________ which carries nutrients, oxygen and carbon dioxide;
_______________________- to transport blood; and a __________________
to pump blood.
A Closer Look at the Three Main Parts:
#1 – Blood
Your blood is made up of ______________ (the liquid part); _______________
which carry oxygen and carbon dioxide; _________________________ which
fight infection and ________________ which help stop bleeding when you cut
yourself.
#2 - There are 3 types of blood vessels: Arteries, Capillaries and Veins
Arteries carry blood _________________ from the heart. The main and
largest artery in the body is the _______________.
Arteries have ______________
walls which makes these blood
vessels strong and elastic.
When we take our ________________, we are actually feeling an artery
expanding and contracting.
Capillaries connect _________________ and __________________. They
are very thin and ______________ blood vessels. Capillaries are so tiny that
blood usually can only get through one cell at a time.
It is in the capillaries that gas exchange occurs. Red blood cells release the
_____________________ gas they carry to surrounding tissues and the tissues
release their waste products, like ___________________. Capillaries receive
blood from __________________ and pass blood to the veins.
Veins receive blood from the capillaries and carry blood back to the
___________________. Veins are not as ___________________ as arteries.
Blood in your veins appears ___________ in colour because veins carry mostly
blood that has little oxygen in it. We call this type of blood deoxygenated.
#3 – The Heart - The heart is made up of 4 compartments, aka ________________.
2 upper chambers: __________________, ___________________
2 lower chambers: __________________, ___________________
Follow the power point and describe the path of blood as it travels
through the heart.
1. Deoxygenated Blood enters the _________________and passes through
a valve into the ________________________.
2. The right ventricle pumps the deoxygenated blood through a valve into the
_____________________________. This artery takes blood to the lungs
to pick up ________________ gas.
3. Blood that is now full of oxygen (oxygenated blood) returns to the heart via
the pulmonary _______________. Blood enters the left
_______________, travels through a valve into the left ______________.
4. The left ventricle pumps the blood through a valve into the largest artery –
the __________________ which connects to other blood vessels that go
the upper and lower body.
Questions:
1. A. What type of blood do you find on the right side of the heart –
oxygenated or deoxygenated?
B. What type of blood do you find on the left side of the heart –
oxygenated or deoxygenated?
2. Draw a diagram of how the blood flows through the circulatory system.
Identify and label important parts of the circulatory system: heart; arteries,
veins, capillaries, lungs, kidneys, liver, blood. (You may do this by hand or
using appropriate software/digitally).
