The Respiratory System  

The jobs of the respiratory system

The breathing in and out of the pulmonary ventilation.The gas changes between the Bloodstream & the Lungs. It includes the way of passage for the oxygen from the air. The gas switch between the bloodstream and the body tissues. This includes the transport of the oxygenated blood from the heart to all the body. The air passes over the Laryngeal muscles which cause  a vibration which produces sound. One of the most important organ of the Respiratory system is the lungs.


The lungs The primary organs of the respiratory system are the lungs, which carry out this exchange of gases as we breathe. The lungs work with the circulatory system to pump oxygen-rich blood to all cells in the body. The trachea /windpipe is a wide hollow tube that connects the larynx/voice box to the bronchi of the lungs. Provides air flow to and from the lungs for respiration. The nose inhales air and out and helps you smell. The mouth helps you exhale air. The throat is your neck and it pushes food down. The voice box makes air pass that makes you speak. The Diaphragm is under the ribs. The bronchial tubes are the tubes connecting from the trachea to the lungs. The bronchioles are like roots from a plant the bronchioles are in the lungs. The alveoli is the little circles inside the lungs it exchanges the carbon dioxide to the oxygen. The capillaries are the smallest body cells in your body.

These are the organs of the respiratory system                                                                

• 

  Aveoli

  Lungs
• Trachea / Windpipe
• Nose and Nasal Cavity
• Mouth
• Throat / pharynx
• Voice box / larynx
• Diaphragm
• Lungs
• Bronchial tubes / bronchi
• Bronchioles
• Air sacs / alveoli
• Capillaries

What system does the respiratory system work with:


The respiratory system work with the circularity system because they both use the lungs to spread oxygen everywhere around the body.

The Analogy of the Respiratory System

The analogy of the system is a tree because the roots of the tree connected to the seed and the seed grows a lot of roots that end up connecting to the tree its self and that is like the veins connected to the lungs to spread oxygen around the body.

The Nervous System

The Nervous System

Nervous Systems Function:

The nervous system controls parts of your body such as your brain, spinal cord, and other nerves. 
Brain:
The brain is the main part of your nervous system,it receives signals from the human body to do regular daily base things such as walking,eating,and much much more.

The Main Organs:
The major organs are the brain,spinal cord,and nerves.

Brain:Your brain is separated into three parts:Your Brain stem,cerebrum,and cerebellum.

Cerebrum: The cerebrum is your learning and thinking part of your brain.

Cerebellum: The cerebellum is part of the brain that lies behind the cerebrum.

Brain stem:The brain stem is part of the brain that lies at the base of your brain.It connects the brain to the spinal cord and coordinates the involuntary muscle movements for functions.

Interactions With Other Systems

Your nervous system interacts with every other systems,your endocrine system works closely with your brain and central nervous system to control the creation of specific hormones and enzymes.Your digestive system and excretory system work with the nervous system in both conscious and unconscious.

Nervous System Analogy: 

The Nervous System Analogy Is Messages
How this works with the nervous system:

This human-like activity does the same job as the nervous system because it receives and sends just like messages.

Bonus:
The brain is the main organ of the Nervous System ,it is made of three parts,your cerebrum,cerebellum and the brain stem the cerebrum is like school because it is are learning space . The cerebellum is like a person on a beam because it helps us have balance. The brain stem is like a structure because it helps structure our body.

The Digestive System

  The Digestive System

Body system Function:  The Digestive system helps your body to digest food.When digestion happens food breaks down into small molecules called nutrients which are absorbed in the body.The Digestive process starts when the mouth takes in food which then goes to the esophagus than the stomach.After the stomach it continues in the intestine then the food leaves the body as waste.

Body  System Organs:  The 3 major organs of the Digestive system are the esophagus,the stomach and the intestines(small and big intestines).

Esophagus: The esophagus is a long tube that connects the throat and the stomach. After the food enters the mouth it goes to the esophagus.Then the food travels down the esophagus to the stomach.

Stomach:The main jobs of the stomach is to store and break down food.The stomach turns to make gastric juice to help digest the food.Food that has been broken down in the stomach is called chyme.

Intestines: Intestines are organs shaped like long tubes.They help break down food so the body can use it for energy.Intestines also remove waste from the body.First it's the small intestine and then the big intestine which is shorter but wider than the small intestine.

Interactions with other systems: The digestive system works closely with the circulatory system to get absorbed nutrients distributed throughout the body.While the digestive system collects and removes undigested solids the excretory system filters compounds from the bloodstream and collects them in urine.

                                    Analogy

  The Digestive system is like a Water park. The mouth is like a pool that collects all the food.The throat/esophagus is like a water slide because all the food slides down the throat.The stomach is like a hot tub cause the acid is like the hot water.The small intestine is  like a water vacuum cause the small intestine sucks up nutrients and a water vacuum  sucks up water. The large intestine is like a water drain cause they both absorb water.

The Skeletal System

1:Skeletal system







2: Image of the selected system








3:Description of the body:The skeletal system is the body system composed of bones and cartilage and performs critical functions for the Human body.

4:The parts of the skeletal system are: the skull which protects the brain,the rib cage which protects the lungs and heart, and the spine which is a long bone connecting from the top of the body to the hips.The mandible is the bottom of the skull.

5:Your skeletal system does not work alone. ... The calcified bones of your skeleton also work with the circulatory system. Marrow inside of your bones helps produce the cells inside of your blood. Both red blood cells and white blood cells are created in your bones.




Bonus:The body of the skeletal system is like the body of the car. It has parts that connect just like one of a car.The bodies are similar because the engine is like the brain of the car, and the body is like the skeleton.







We got the image of the skeleton from a site called miss Jackson science 7,


We got the image of the car from a site called information parlor.





                           

The Immune System

The Immune System

The  immune system is the system that protects the body from  biological germs and viruses.                                           

 In order for your immune system to function properly, it needs to sense a big selection of agents, known as white blood cells to  parasites and fight the different bacteria and viruses in our body.

 The Mucus Membranes

The Mucus Membranes are used to make the mucus in your nose. And the mucus that the mucus membranes make is used to protect your body from Viruses and microbes. How it 

Works are that when microbes or viruses entre from your nose, they get stuck in the mucus and the mucus in a short time hardens.

Tonsils

The Tonsils help the immune system by stopping germs to continue into the esophagus. Inside the Tonsils, there is a lot of white blood cells and antibodies to kill the germs.

Lymphatic Vessels

The Lymphatic Vessels are a really important part of the immune system. The Lymphatic Vessels bring lymph fluid who contains antibodies and white blood cells to the part of the body where they need them.

Lymph Nodes

 The lymph nodes are used to filter Harmful Bacteria and cancerous cells. And it helps your body with infections. Finally, it has a big role in cancer diagnosis and treatment.

Thymus 

The Thymus is used to make T cells. does T cells are used to produce white blood cells.

Skin

The Skin is used to stop bacteria and viruses and to stop infections from happening. And the skin has substances that are used to fight germs.

Spleen

The Spleen plays multiple roles in the human body. It acts as a germ filter for red blood cells. Our Platelets and White Blood Cells are stored in the Spleen. And the Spleen helps fight certain types of bacteria. 

Bone Marrow

The Bone Marrow is used to make red and white blood cells, platelets, and Lymphocytes.

In some species and humans there are two important subsystems which are the flowing;innate immune system and  adaptive immune system How the innate immune system works; this subsystem works and protects your body from viruses before it spreads and infects your body.

The immune system works with the circulatory system.

It works closely with this system to transport needs to the lymphatic system.

Analogy:

The immune system is like a security camera in a bank that catches a robber

. catches Viruses and germs

. catches robbers like the immune system catches diseases .

The Excretory System

Excretory System

Body System Function:

The Excretory System removes solid, liquid and, gaseous waste.

Body System (major) Organs: 

Kidneys:
The body has two shaped-like beans that filter blood from the urine.

Large Intestine:
It holds the material that can’t be digested. It absorbs the remaining water trapped in the food waste.The remaining part comes out of the body called feces.

Liver:
Located on top of the stomach, it makes a bile (a greenish-brown fluid),

stored in the gallbladder. The Bile breaks up fat molecules in the
small intestine which goes down to the large intestine.

Skin: It is the body's largest organ, this organ removes liquid.The top
layer of skin contains millions of sweat glands.These sweat glands release wastes in the form of sweat,

excess water, and urea (a protein). 

Interaction with Other Systems:

The excretory system has a close partnership with both circulatory
and endocrine systems.The blood circulates through the body
and passes through one of the two kidneys. Urea, uric acid, and water
and removed from the blood. Most of the water is put back in the system.

The excretory system also has a close connection with the digestive
system. It collects undigested solid.The excretory filters to compound from the
bloodstream then it collects from the urine. They control the amount of the body's
water. 

The excretory system has another connection with the respiratory
and urinary system. The lungs in the respiration removes waste products such
as carbon dioxide. 

The excretory system has a connection with the muscular and
nervous system. It has an interaction between our muscles and our nervous
system. Our endocrine works closely with our brains and our central
nervous system to control our creation of specific hormones and enzymes. 



Analogy

Analogy Explanation
The water filter system is a good analogy for the excretory system. It is a good example because both the systems jobs are to remove waste and purify.
