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.
Nose
The nose is one of the ways air comes go into your body. The air is not as clean as you think. Dust, pollen, sand, and other microscopic particles flow through the air. When the air goes into your nose their are tiny hairs called cilia that line the walls that catch the particles. The reason your nose is wet is because mucus that is on the cilia that sticks the particles to the cilia and when there is a lot of particles you sneeze. Inside your body air gets warmed by the body which it has to be. Before it goes done the trachea it needs to be warmed and the way it gets warmed is by the capillaries. They are like mini arteries that are near the skin surface of the skin membrane. The are on the top of the nose and runs warm oxygenated to the top of your head. That warms the inside of your nose which warms the air passing through.
Mouth
The mouth is the other way air gets to your lungs. Your mouth is is warmed by the heat rising from you inner body. If you read about the nose then your wondering what filters the air when it goes through the mouth. Well when the air goes down your trachea there is cilia lining your trachea. The way the particles exit is a little like how your nose does it. When their is a build up in your trachea you will start to cough which pushes the particles out through your mouth. Other than that Co2 (carbon dioxide) is a waste product that leaves through the mouth or nose.
Larynx
The larynx is the next part of the path the lungs. It is one of the two paths that separate the lungs from the stomach. The two tubes are right beside each so what makes sure air doesn’t go into the stomach and food not go into the lungs. It is called the epiglottis which is a flap of tissue that seals of your pharynx (tube that goes to your stomach) or larynx. The larynx contains voice cords. When are hits them they vibrate creating sound in order for you to talk. Your muscles in your cheeks, lips, and mouth make the sounds into words. The larynx is more commonly known as the Adam’s apple. If you were to outline your larynx it would look like an apple. This is what makes your voice go deep. Woman also have an Adam’s apple but men’s Adam’s apples are bigger.
Trachea
The trachea is right before and after the larynx. It is lined with cilia like the nose to catch particles from the air gone in from the mouth. But, instead of mucus on the cilia it is saliva. It is lined with cartilage between beach bone so when you bend your neck it will bend no crack.
Bronchi
Soon after the trachea the bronchial tubes start. They split and go into the lungs. They start to get smaller and smaller which then are called bronchioles. Once they reach the lungs they branch out and like a tree’s branches. At the ends there are alveoli. The bronchioles bring the air to the last stop in the lungs.
Alveoli
The alveoli are tiny microscopic balls at the ends of bronchioles. They are not evey singled out they are always in groups. They transfer air into the blood stream. The walls of the alveoli are about a cell thick so air can pass through it. When it passes through the alveoli it goes straight into the blood stream. They are what get damaged the worst by smoking. When there is to much CO2 in an alveoli it can’t put it anywhere an get damaged and usually dies. This is why many smokers have a hard time breathing. They don't have enough oxygen in their lungs.
Diaphragm
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.
COPD
Bronchitis
Pulmonary Fibrosis
Homeostasis
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.
