Bronchitis
|
When a microorganism such as a virus of bacterium causes an infection in the tube that branch off the trachea, the infection is called bronchitis.
|
|
|
Alveoli
|
The lungs are made up of millions of alveoli which are located at the end of bronchioles. They have lots of capillaries where the exchange of oxygen and carbon dioxide takes place.
|
|
|
Ribs
|
Muscles that are located between the ribs contract and relax helping to move air in and out of the lungs.
|
|
|
Celular Respiration
|
In cell, when sugar and oxygen combine to produce energy, carbon dioxide and water are also produced. The reaction is called cellular respiration.
|
|
|
Tars
|
Tars are sticky brown substance that are found in cigarettes. They collect in smoker's lungs, irritate the cells, and prevent oxygen and carbon dioxide from being exchanged.
|
|
|
Nicotine
|
The addictive chemical found in tobacco is called nicotine. It affects the nervous system and smokers crave the felling they get when they smoke cigarets.
|
|
|
Carbon monoxide
|
Is a poisonous gas in cigarette smoke. It attaches to hemoglobin and then oxygen cannot be carried by red blood cells. The chemical symbol is CO.
|
|
|
Emphysema
|
Emphysema can occur when the alveoli are damaged by smoke. Breathing becomes difficult.
|
|
|
Sulfur Dioxide
|
a gas found in polluted air. It irratates eyes, nose, throat, and damages the lungs. The chemical symbol is S02.
|
|
|
Nitrogen Dioxide
|
A gas found in polluted air. It irratates the eyes and nose and can cause bronchitas and pnemenia.
|
|
|
Chemical Reaction
|
Sugar + Oxygen (arrow) enegy + carbon Dioxide + water is the chemical reaction for cellular respiration
|
|
|
Pollution
|
Air that is "dirty" enough to cause health issues is referred to as air pollution
|
|
|
Larynx
|
the larynx is the firm structure at the top of your trachea. It is called the voice box or adams apple and contains the vocal cords. When air passes through the vocal chords, they vibrate making sounds that produce speech.
|
|
|
Respiratory System
|
The major parts are the nose, mouth, trachea, and lungs. These parts and others help deliver oxygen and other gasses to the blood and removes CO2 and other waste products from the blood.
|
|
|
Epiglottis
|
A flap of tissue that covers the opening to your trachea when you swallow. It's function is to keep food and water from entering the trachea.
|
|
|
Bronchi
|
The bottom of the trachea splits into two branches called bronchi. Each one goes to a lung and delivers air to it.
|
|
|
Mucous Membrane
|
The nose is lined with this mucous membrane. It moistens the air to prevent lung tissue from trying out.
|
|
|
Pneumonia
|
Caused by an infection in the lungs. It can be caused by microbes like bacteria and virus, or by irritation from particles or gasses. Symptoms may be a painful cough and fever. The primary result is a build up of fluids in one or both lungs.
|
|
|
Trachea
|
Starts at the top of your throat and is in front of the esophagus. It connects the lunch with your pharynx and allows air to enter your lungs.
|
|
|
Cilia
|
The trachea and bronchi are lined with very fine hair-like structures called cilia. They wave back and forth moving mucous along with dust and other particles up and out of the respiratory system.
|
|
|
Bronchioles
|
Each bronchus (singular for bronchi) branches in to several smaller and smaller tubes called this (bronchioles) and are connected to the alveoli.
|
|
|
pharynx
|
Your nasal cavity and your mouth join at the back of your throat at this - the pharynx.
|
|
|
air quality index
|
An index used to report daily air quality for five major air pollutants: ground-level ozone, particle pollution (also known as particulate matter), carbon monoxide, slufur dioxide, and nitrogen dioxide. It ranges from 0-500. The higher the AQU value, the more polluted the air. Values above 100 are considered to be unhealthy - at first for certain sensitive groups of people, then for everyone as the values get higher.
|
|
|
Diaphragm
|
A large flat muscle located at the bottom of the ribcage, It separates the chest from the abdomen. During inhalation, the diaphragm contracts, which increases the volume of the chest and air will rush into the lungs. During exhalation, the diaphragm relaxes and pushes on the lungs, which forces air out.
|
|
|
Ozone
|
When nitrogen oxides are exposed to sunlight, molecules of o3 ozone are formed. The levels are highest in daytime and cause lung and eye irritation, and damages plants and manufactured materials such as rubber.
|
|
|
Air
|
Air is about 79% nitrogen 20% oxygen and 1% other gasses.
|
|
|
Solid Suspended Particles
|
The dust, smoke, soot, ash, and pollen are in the air, they are referred to as solid suspended particles.
|
