The Respiratory System

                      The Respiratory System


           

                        
                           Respiratory System Function

Your respiratory system allows you to laugh,talk, and sing.The respiratory system
brings oxygen into your body and gets rid of carbon dioxide.
Your cells need oxygen to grow,work,and keep your body working.
When cells do their jobs they give carbon dioxide.

Organs used in the System:

Nose: The moisture in the nose helps to heat to heat and humidify the air,making the amount of water vapour entering the lungs.This prevents the air from drying out the lungs and other parts of the respiratory system.

Pharynx:The pharynx is like a passage way for food it also takes the air in and leads to your stomach and lungs.

Larynx: The larynx is a strong but  a flexible segment of the respiratory  tract connecting the pharynx and the trachea in the neck.it plays an important role in the the respiratory tract  by letting air to pass through it while keeping food and drinks from blocking the air way.

Trachea:The trachea  is a wide, hollow tube that connects the larynx  to the bronchi of the lungs. It is an integral part of the body's airway and has the vital function of providing air flow to and from the lungs for respiration.

Bronchi: The bronchi is known  as a bronchus are extensions of the windpipe that shuttles air to the lungs and from the lungs.they are part of the conducting zone of respiratory system.

Lungs: The lungs in the respiratory system allows us to breathe.Our lungs bring oxygen into our body called inhalation and send carbon dioxide out called exhalation.The exchange of oxygen and carbon dioxide is called respiration.

                            
                       Interaction With Other System

Our Respiratory system works best with our circulatory system,as Oxygen taken in
from the respiratory system moves into blood vessels that then circulate oxygen-rich blood to tissues and cells.

Analogy

Analogy Explanation

The tree branches separate out in branches just like the bronchi does from the larynx.

The tree roots are like the larynx they connect to the tree trunk.

• The bronchi separates out like branches    
• Form the shape of upside down lungs     

A tree is like lungs with the branches as the bronchi from the larynx like the tree roots.
the tree trunk is like the trachea it supports the tree like the trachea does to the lungs.

The Digestive System

The Digestive System

Function of Digestive System work

The function of the digestive system is digestion and absorption.
Digestion is the breakdown of food into small molecules,esophagus  and goes to the
stomach to the small intestine then to the large intestine then to your anus.

The Body System Organs

The main organs of the digestive system are Salivary glands,Pharynx,Stomach,
Small Intestine large Intestine Rectum Accessory.
digestive organs: liver, gallbladder, pancreas.

Interaction With Other Systems

The system that help with the digestive system are circulatory system and
the endocrine system that controls the speed of the digestive system.

  

Analogy

The digestive system is a frame of a water park.
When you slide it is like you are going to your intestine.

The Excretory System

                                                                                                   Excretory System

                                  

Excretory System Function: The excretory system is
the biological system responsible for removing excess
and unnecessary materials from the body fluids of an
organism to help maintain internal chemical homeostasis
and prevent damage to the body. This system eliminates
waste products. 

Excretory System Organs:
       

Kidneys: Removes liquid waste and salt from the blood to form urine.

Ureters: Tubes that carry urine from the kidney.                                           

Bladder: store urine and will expand when lots of urine is stored.     Sphincter: Circular shaped muscles that prevent urine
from leaking out of the bladder.  

Urethra: The tube that allows urine to leave the body.                         

        Interaction with other Systems

  The Excretory system works with the Digestive system because it collects waste in the intestines. It also works with the circulatory system because it collects blood waste products in the blood. Another system it works with is the urinary system because it removes liquid waste.

               Analogy 

Analogy Explanation

The excretory system is similar to a garbage truck/dump because a garbage truck takes the trash/waste from your house(a.k.a blood cells) and drops it off at the dump/kidney. Then the workers at the dump, sort out metal, plastic, glasses,e.t.c and throw the non-recyclable things in a compressor to be crushed while recyclable things are sent recycling plants to be re-used.

The Circulatory System

THE CIRCULATORY SYSTEM

                                           

What is Circulation? The movement of blood is called circulation.  

VEINS: The blood vessels that carry blood back to the heart.

PULMONARY CIRCULATION: The circulation of blood as it moves through the heart, to the lungs, where it picks up oxygen,and travels back to the heart.

SYSTEMIC CIRCULATION: The circulation of oxygen- rich blood as it travels to all the body tissues and organs.

CORONARY CIRCULATION: The circulation of blood to and from the tissues of the heart.

VALVES:  There are valves in our heart too! They are located between chambers and act like doors that open only one way to let blood flow in or out. The TRICUSPID VALVE opens from the RIGHT ATRIUM into the RIGHT VENTRICLE. The PULMONARY VALVE opens from the RIGHT VENTRICLE letting the blood flow into the PULMONARY ARTERY leading out the heart. 

HEART:

The HEART is the size of your fist. Your heart pumps blood throughout your body. It is like a muscle. As the muscle contracts, it squeezes blood out and around our body. The heart is a muscle, that is divided in 2 halves, one identical to the other. One half receives blood from our lungs while the other sends blood to travel back to the lungs.

BLOOD CELLS:

There are WHITE and RED BLOOD CELLS in our body. RED BLOOD CELLS carry oxygen and remove carbon dioxide and WHITE BLOOD CELLS help the body fight diseases.  

PLATELETS:

PLATELETS help blood clot when you have an injury.

ARTERIES:

Arteries carry blood away from the heart and veins carry blood back to the heart.

The Three Independent Systems

  The Circulatory System consists of three independent systems that work together:

• The heart (Cardiovascular)
• Lungs (Pulmonary)
• And arteries, veins, coronary and portal vessels (Systemic)

	ANALOGY Our Circulatory System is like roads and highways. The veins and arteries are the roads and the highways. The arteries and veins carry blood and blood cells, are the cars that come and go to only destination: the heart.The heart is the key to this whole system. The arteries come from the heart to the body,and the veins carry blood from the body back to the heart. The veins are the pickup truck, picking up the blood from the body. The arteries are the cars that leave blood in the body.

Functions

Oxygen Rich blood	The oxygen rich blood from the lungs enters the left atrium and goes to the left ventricle through a valve.
	The left ventricle pumps blood out through another valve.
	The aorta, which is the main artery, branches into smaller arteries that carry blood to all parts of the body.

     ⇓

Oxygen Poor blood	Veins carry the oxygen poor blood from the head and the body back to the heart. The blood flows into the right atrium.
	The blood goes to the right ventricle.
	The right ventricle pumps blood to the lungs.

⇓  

The blood leaves carbon dioxide in the lungs and picks up oxygen. Veins from the lungs bring blood carrying oxygen back to the heart.

It is all a cycle! It repeats over and over again!!

The Nervous System

                                              Nervous System                

     Nervous System Functions
The nervous system is made up of the brain, spinal cord and nerves. It is the
body's communication system that controls much of what your body does. It allows
you to do things like walk, speak, swallows, breathes and learn, and controls how
your body reacts in an emergency.

Organs Of The Nervous System
The major organs of the nervous system are the brain, spinal cord and sensory organs. The brain controls our thoughts, memory and speech, movement of the arms and legs, and the function of many organs within our body. The spinal cord has three major roles such as to relay messages from the brain to different parts of the body, to perform an action, to pass along messages from sensory receptors to the brain, and to coordinate reflexes that are managed by the spinal cord along. The sensory organs are the eyes, ears, tongue, skin, and nose help us see, hear, taste, feel and smell.

                      How The Organs Work With Other Organs In The Nervous System!!

The nervous system works with many other systems. One of the example is the skeletal system. The bones provide calcium that is essential for the proper functioning of the nervous system. The digestive system works with the nervous system by providing the building blocks for some neurotransmitters and for the respiratory system the brain monitors respiratory volume and blood gas levels. The muscular system works with the nervous system, for example by receptors in muscles provide the brain with information about body position and movement.

Analogy Image

Nervous System Analogy :

In the human body, the nervous system is the master system that controls all other body organs, to perform its functions. In the Car, the computer system is controlling all functions of the brain in the nervous system. 

In the human body, the nervous system passes its signals through millions of neuron cells.  In the Car, the computer system passes its signals through many tiny wires and smart chip units.

In the human body, the brain is able to recognize and analyze our vision. In the car,
the computer is able to recognize and analyze the surroundings by cameras, radars
and ultrasonic sensors. 

Bonus: Analogy: The immune system works like what happens when a prisoner is breaking out of their cell. Pathogen: a pathogen is something that can cause illness that is trying to enter your body to infect your cells. In the prison break analogy the prisoner is the pathogen. Both are trying to break through something.
