Respiratory System

By Ryan Gause

Respiration System

It is the system that makes you breath. It is made up of your theoretic cavity (lungs, ribs, and diaphragm), the voice box or larynx, the windpipe or trachea, the epiglottis, nose, mouth, and bronchial tubes. The lungs are two sponge like structures that hold air that then gets transferred to the blood stream.


The diaphragm is a muscle below the lungs and helps you breath. When you breath in it contracts and pulls down expanding the lung. When you breath out the diaphragm expands pushing up contracting the lungs, pushing the air out. It is also a product hiccups. The diaphragm will have a muscle spasm. Which leads to air being pulled in fast and pushed out fast.

What is homeostasis, homeostasis is when the body is able to to sustain a stable internal environment. This means your body can sustain a normal level of certain parts in your body.

Some examples is the heart keeping a steady pace so there is the right amount of oxygen, or the lungs keeping a steady breathing rate so their is not to little oxygen or to much.

Types of Homeostasis


Humans are warm-blooded so they don't constantly have to be in warm temperatures. Your body keeps itself heated by working internal parts. But if your body is not in homeostasis with temperature you could start to sweat (if hot) or shiver (if cold). If your body gets to the internal temperature of 113 degrees fahrenheit you body will start to durn up and die.


When you have eat you take in energy. When that happens your body has the nutrients to preform daily routines. Also when preforming these daily routines you body produces heat from working muscles to keep a normal temperature. When taking in energy it helps you move also keeps suger levels in check.


You lungs bring in oxygen which is caries into the blood stream and throughout your body. Your body doesn't just need nutrients to preform daily routines but also oxygen. If your body doesn't have enough oxygen then you become weaker. You brain sends off nerve waves to the diaphragm to contract pulling down and expanding the lungs. When this occurs oxygen is brought in to the lungs an to the alveoli to be transferred into the blood stream. When in the blood stream oxygen gets transported to organs and tissue to be used. Once it is converted to CO2 it is transferred to your veins to be taken back to the lungs to be exhaled out of your body.
