Organs:
They Essential Building Blocks for Plants and Animals
Cells
• Every thing that builds up your body comes down to cells.
• Cells are the building blocks to…the building blocks of your body.
• Cells are very unique and are build to help keep all parts of your body
in a constant flow so you can live.
• Lets look at what kind of materials a cell contains.
Cells in general
• All cells can be different but all come down to basic materials they
contain.
• In all cells there is a Nucleus, the main generator for the cell.
• There are many other materials such as Mitochondrion, a Ribosome,
and a cell walls.
• They all contain different attributes that help the cell
• An attribute a plant cell contains that an animal doesn’t which is hige it
a central vacuole which is the clear fluid spaced part of the cell
Circulatory systems
• Blood is the fluid that transports nutrients to all parts of your body.
• It is made up of Red Blood cells, White Blood Cells, Platelets, and
Plasma
• It is made to support and protect you from diseases and germs.
• The central generator that keeps blood moving throughout the body is
the Heart.
The Heart
• The Heart lays behind your lungsslightly to the left.
• The four chambers it contains are the left and right atrium, and the left and right
ventricle.
• Man and mammals have a double circulation system improving the performance
and amounts it can pump
• The blood it pumps contains high amounts of oxygen which all parts of the body
needs.
• The average heart rate of a person is 72 beats per minute. This means in a day
your heart pumps 103,680 times and in a year 37,843,000 times.
Lungs
Respiratory System
• The Lungs job is to intake air, which contains mostly Oxygen,
nitrogen, and Carbon dioxide.
• Its goal is to have oxygen enter the body while releasing the nitrogen
and carbon dioxide
• The Lungs take air in, the Oxygen goes through the Alveolus wall and
through the capillary wall into your blood. Carbon dioxide and water
pass from the blood into the alveoli
The Nose’s Job
• The Nose contains hairs which trap solids that would harm the lungs
such as Dust, Foreign Particles, and Bacteria.
• Mucous membrains in the nose have cells that can sense harmful
chemicals
Harmful diseases
• Chronic Bronchitis can inflame and irritate lungs and airways making
it difficult to breathe. When Irritated your airways create a mucous that
makes it worse for breathing.
• Emphysema
• Asthma
• Lung cancer
The Digestive System

There are many different parts of the digestive system. They include:
The Mouth
The Oesophagus
The Stomach
The Small Intestine (also called Duodenum, Jejunum, or the Ileum)
The Large Intestine (also called Asending, Transverse, descending
colon
The Salivary Glands
Liver
Pancreas
Glass Bladder

The Digestive system’s job is to Intake Food with nutriants
The digest and break down food into soluble and diffusible forms
To absorb food by using cells
Egestion and/or elimination to remove undigested waste and materials
Process
Saliva starts to break down foods in the mouth as it is chewed and broken
down for the stomach
The Teeth break down the food
The Oesophagas contracts the food down into the stomach with Peristalsis
which is a wave like form that gets the food down
The food is put into the stomach which contains think muscular walls which is
lined on the inside with gastric glands and gastric juices which break down
foods.
The food is churned and mixed well in the juices
The Food remains in the Stomach for around 3-4 hours before it moves on
It moves onto the Small Intestine which contains Intestinal juices, Protease and
Lipase which are digest proteins and fat.
The Large intestine absorbs water and minerals which is disposes of
undigested and un absorbed matter.
The product that comes out after digestion are simple sugars Proteins, and fats
The Excretory System
•
•
•
•
What organs in your body are considered part of the excretory system?
Your Lungs removing Carbon Dioxide from you body
Your Liver which removes Bile through your intestines
Your Skin which removes salt and small amounts of urea (chemical
found in urine)
• Your Kidneys which removes Urine.
• Excreation is the process where metabolic waste products and materials are
removed from the body of an organism.
• This is what the Excretory system does is remove all of the waste that was not
used to fuel the body out.
• Some Metabolic wastes are
• Gases like carbon dioxide
• Liquids such as water
• Solids made from the breaking down of amino acids and hemoglobin
• Heat
• The excretory system also includes the release of wastes
• This is the urinary system which gets rid of the excess liquids unused
by your body
Urinary System
• The different parts of the Urinary System are.
• The Kidneys- Kidneys filter contain Nephrons which clean blood by
filtering, reabsorbing, and the Excretion which is the creation of Urine.
The urine then moves onto the Ureter
• The Ureter- The Ureter which is a long tube that takes in Urine and
conveys it for the next stages.
• The Bladder- The Bladder receives the Urine and holds it until released
into the urethra where it is disposed of.
The Nervous System
• The nervous system is very important being able to work all of our
senses
• It runs all different parts of our body, it works a lot like the electricity
does in our cities
• The brains is our source of energy running everything
• The spinal cord is the wiring sending information and signals all round
the body
• Finally the nerves and senses take this energy and information and give
and take from the brain.
• The nervous system helps you react or sense what is around you with
being able to see, touch, hear, smell and taste.
• It can help you react to things like burning yourself or tripping making
quick moves to keep you out of harm.
• All nerves that run the body are protected accept one which is your
funny bone.
The Brain
• The brain is the master mind behind the whole operation of your body.
Made up of over 10 billion nerves
• There are three main parts of your brain. The Cerebrum, the
Cerebellum, and the brain stem
• The Cerebrum is the largest part of your brain, it controls you thinking,
memory, movements, information from your organs, and speaking.
• The Cerebellum controls your balance and posture.
• The Brain stem connects the brain to your spinal cord. It also controls
the beat of your heart, your breathing, and your blood pressure.
The spinal cord
• The spinal cord is made up of many vertebrae, which are the bones that
connect together to build up the spinal cord.
Sense Organs
• Sense organs are organs that include the eyes, ears, nose, tounge, and
skin. They gather information from light, sound, heat, and pressure to
send to the brain.
Conclusion
• Organs make up our body. They are the essential tools to help us live
and help us interact with the world and help us live our lives.
• It is a very big topic with many different parts, which describes the
body which is an amazing piece of work that is able to work with
environments and others helping us unconsciously breathing, digesting,
and constantly changing
