Let blood go either in or out.
What is it?
Your heart is actually a muscle. It is located
a little to the left of the centre of your chest
and is about the size of your clenched fist.
The heart is special because it pumps blood all
around your body. The blood provides all of
your muscles with the oxygen and nutrients it
needs. It also carries away waste.
Your heart is a bit like a pump, or two pumps in
one.The right side of your heart receives
deoxygenated blood from your body and
pumps it to the lungs, where gas exchange
occurs, whereas the left side of your heart gets
the blood from the lungs and pumps the
oxygenated blood around your body.
Your heart is part of
something known as
your circulatory
system.
Facts!
The heart is the most
important organ in our
body!
Your heart is well
protected by your rib cage
Electricity going
through your heart
makes the muscle
cells contract
The study of the human heart and
its various disorders is known as
cardiology
Everyday, your
heart creates
enough energy to
drive a truck for
20 miles.
Your heart beats over
100,000 times a day!
Heart disease has
been found in 3,000
year old mummies
The first heart cell
starts to beat as early
as 4 weeks
In an average lifetime,
a human hearts pumps
enough blood to fill 100
swimming pools.
Lungs
Parts of the lungs...
Bronchi
Two 'tubes'. One leads to the right
lung and the other leads to the left
lung. They come off the trachea.
Bronchioles
Smaller tubes that branch away
from the two main pipes
(Bronchi).
Trachea
Also known as the
windpipe. The trachea
filters the air we inhale and
branches into the bronchi
Alveolus
Tiny air sacs one cell thick,
covered in capillaries, this is
where gas exchange occurs.
Lungs
The main organ of the respiratory system. Lungs are
the site in which oxygen is inhaled and transferred
into our blood ad also where carbon dioxide is
expelled out.
Diaphragm
The diaphragm expands and contracts
thus changing the air pressure inside of
your body causing you to suck in air
otherwise known as inhaling.
Gas exchange is the process in which the
oxygen inhaled by the lungs enters the
alveolus and then the oxygen transfers
into our capillaries and blood, so it can go
around our body and help our muscles.
Facts!
Most vertebrate animals
(animals with spines) have
two lungs
When resting, the average adult
breaths 12-20 times a minute
The average person breaths in
around 11,000 litres of air
every day.
The study of lung diseases is known as
pulmonology
People who have a large lung capacity can send
blood around they body quicker. To increase your
lung capacity you just have to do regular exercise!
There are about 600 million alveoli in
your lungs and if you stretched them
out they would be the size of a tennis
court.
The breathing rate is quicker in
women and children than in men.
It is the only organ in your body
that is capable of floating on
water!
What are they?
The lungs make up one of the largest organs in your body,
and they work with your respiratory system to allow you to
take in fresh air, get rid of stale air, and they even allow you
to talk.
Lungs are in your chest and are also the site
in which oxygen is inhaled and transferred into
your blood stream and also where carbon
dioxide is expelled from the body.
The lungs are often compared to being like a
sponge like substance.
Lung are a very important organ
and without them we would die
