The Brain
Insert facts you leaned about the brain
you may also insert 1-2 pictures
The brain is in the top part of the head. The bones of the skull protect it.
The brain is gray and bumpy. It is the size of a large grapefruit.
The brain has many jobs to do. It tells the body how and when to move.
The brain tells you what you are seeing, hearing, smelling, or tasting.
When you touch something hot, the brain tells you it hurts. The brain is
also where you feel anger, sadness, or joy.
Messages travel from the body to the brain. Then the right side of the
brain tells the left side of the body what to do. The left side of the brain
takes care of the right side of the body.
The brain has three main parts. The largest part is called the cerebrum.
This is where you learn, remember, and think. The cerebrum comes up
with new ideas.
The second part of the brain is the cerebellum. It is found behind and
under the cerebrum. The cerebellum tells the muscles what to do such
as walking, running, and playing sports.
The brain stem is the last part of the brain. It is below the cerebrum and
the cerebellum. It takes care of movements that are automatic. You do
not think about automatic movements. They happen by themselves.
Coughing, sneezing, and swallowing are all automatic movements. The
brain stem tells the heart to beat. It makes you breathe and tells your
body to digest food.
With its many jobs, the brain is one of the most important parts of the
body. It helps keep you alive.
The Heart
Describe facts about the heart
• About the Heart
• The heart is a powerful pump. It beats about
100,000 times every day to circulate blood.
Each heartbeat sends about one third of a pint
(0.16 liters) of blood through the body. The
heart continues to work whether you are
awake or asleep.
• The cardiac, or heart, muscle is like tough
strands of rope. Unlike other muscles, the
heart does not get tired. The heart never stops
beating. When a person is active, the heart
works harder. When a person is asleep, it
slows down
The Lungs
Insert the fascinating
facts you leaned about the lungs.
The average person breathes more than 20,000 times a day!
Why do you breathe? And how do your lungs work?
The cells in your body need nutrients from food and oxygen from the air.
Both produce energy and help you grow. Without these elements, your
cells would die. Your lungs take the oxygen you need from the air. The
mechanism inside your lungs that makes this possible looks like an
upside-down tree. Air enters your body through your nose and goes
down your throat to your windpipe. This windpipe branches into two
slightly smaller tubes that look like the main branches of a tree. Each
tube enters a lung. Inside your lungs, these tubes divide several more
times and become even smaller. They resemble the limbs of a tree.
Finally, these tiny tubes end in balloon-like air sacs called alveoli (alVEE-oh-lie).
Each tiny alveolus is surrounded by small blood vessels called
capillaries. Oxygen molecules from the air you breathe pass easily
through the walls of the alveoli and into the tiny capillaries. This is
where the blood gets all the oxygen it delivers to the cells of your body.
The Liver
List facts about the liver
The liver is one of the most important and largest body
organs. It has at least 5,000 functions that help to keep
the body running smoothly.
Blood comes to the liver from the stomach, intestines,
and the spleen. This blood has many nutrients in it to give
the body energy and other materials that it needs. The
liver breaks down these digested nutrients even further. It
collects those that will be useful to the body and removes
old cells from the blood. It stores and releases others
such as glucose sugar, fats, iron, and vitamins,
depending on the body's needs.
The liver also breaks down certain substances that may
be poisonous or toxic to the body. It turns these toxins
into harmless substances or sends them to the kidneys to
be passed out of the body. This is called detoxification
(de-tox-i-fi-CA-tion). Everything we eat, breathe, and
absorb through the skin must be purified and detoxified
by the liver.
The Stomach
Analyze your findings about the stomach
Do you ever hear a growling noise when your hungry?
The noise does not come from the stomach. It comes
from the rather violent churning that goes on all the time
in the long tube below your stomach, the intestine. The
noise is more noticeable when the intestine also
contains bubbles of gas produced by the many helpful
bacteria that live there. You will hear noises from
movements of the intestines almost any time you put
your ear against someone's tummy. Sometimes the
noises are louder, and then you may say that your
stomach is "grumbling." That rumbling is called
borborygmus (BOR-buh-RIG-muss). That may not be a
very useful word for most of us, but it's fun to say.
Small and Large Intestine
Compare facts about the small and large intestine
HOW YOUR INTESTINE WORKS
The intestine is a long tube made up of two parts.
The first part is the small intestine, which is 2.5
centimeters (1 inch) wide and 6.5 meters (22 feet)
long. The small intestine receives partly digested
food from the stomach and digests it further. The
resulting nutrients are then passed through the wall
of the small intestine into the bloodstream, and the
indigestible food moves along into the large
intestine. The large intestine is almost three times
wider than the small intestine but only one-quarter
as long. It eliminates food that can't be digested
from the body in the form of feces.
The inner wall of the small intestine is lined with
millions of tiny fingerlike projections called villi. The
millions of villi increase the inner surface area of the
small intestine to the size of a tennis court. That
large but compact surface area maximizes the small
intestine's ability to pass food into the bloodstream.
Write a complete paragraph on
what you learned.
The brain is the most important part of our body. It sends messages throughout
our body. Our heart is also important it never stops working. It even works
as we sleep. The lungs carry oxygen to the blood and delivers it to the cells
in our body. The stomach has the job of churning our food on the journey to
digestion. The small and large intestines help further the digestion. Our food
is finally digested throughout the large intestine. The Liver also has a major
job, while our food is digesting the liver cleans it out. The liver purifies and
detoxifies everything we eat, breathe and absorb. Our organs are very
important and we must help keep them healthy.
