Nasal Cavity (Nose)
lined with a mucous membrane that helps keep your nose moist by making mucus so you won't get nosebleeds from a dry nose.
helps to regulate the temperature and humidity of the air your breathe in, as well as to lighten the bone structure of the head and to give tone to your voice.
Oral Cavity (Mouth)
air can enter in your mouth, especially if you have a mouth-breathing habit or your nasal passages may be temporarily blocked.
overgrown lymph tissues at the top of the throat. When your adenoids interfere with your breathing, they are sometimes removed.
lymph nodes in the wall of your pharynx. Tonsils are not an important part of the germ-fighting system of the body. If they become infected, they are sometimes removed.
collects incoming air from your nose and passes it downward to your trachea
flap of tissue that guards the entrance to your trachea. It closes when anything is swallowed that should go into the esophagus and stomach.
Larynx (Voice Box)
contains your vocal cords. When moving air is breathed in and out, it creates voice sounds.
passage leading from your mouth and throat to your stomach.
the passage leading from your pharynx to the lungs.
is the strong wall of muscle that separates your chest cavity from your abdominal cavity. By moving downward, it creates suction to draw in air and expand the lungs.
help oxygen from the air we breathe enter the red cells in the blood. Red blood cells then carry oxygen around the body to be used in the cells found in our body. The lungs also help the body to get rid of CO2 gas when we breathe out.
The trachea divides into the two main bronchi (tubes), one for each lung. The bronchi, in turn, subdivide further into bronchioles.
The smallest section of the bronchi are called bronchioles, at the end of which are the alveoli (plural of alveolus).
the very small air sacs that are the destination of air that you breathe in.
blood vessels that are imbedded in the walls of the alveoli.
Your airways narrow and make too much mucus.
Inflammation and infection make your bronchial walls thicker.
Chronic obstructive pulmonary disease (COPD)
This long-term condition gets worse over time. It includes bronchitis and emphysema.
An infection causes inflammation in your alveoli. They might fill up with fluid or pus.
A bacterium causes this dangerous infection. It usually affects your lungs but might also involve your kidney, spine, or brain.
Cells in your lung change and grow into a tumor. This often happens because of smoking or other chemicals you’ve breathed in.
This disease is caused by a problem in your genes and gets worse over time. It causes lung infections that don’t go away.
Too much fluid builds up between the tissues that line your lungs and chest.
Idiopathic pulmonary fibrosis
Your lung tissue becomes scarred and can’t work the way it should.
Tiny clumps of inflammatory cells called granulomas form, often in your lungs and lymph nodes.
Objectives:1. Become familiar with the system responsible for taking in oxygen and expelling carbon dioxide.2. Become familiar with how the respiratory system works.3. Become knowledgeable of the chemical process happening in our bodies.
Hairs in your nose help filter out large particles. Tiny hairs, called cilia, along your air passages move in a sweeping motion to keep the passages clean. But if you breathe in harmful things like cigarette smoke, the cilia can stop working. This can lead to health problems like bronchitis.
Your respiratory system has built-in methods to keep harmful things in the air from entering your lungs.
Cells in your trachea and bronchial tubes make mucus that keeps air passages moist and helps keep things like dust, bacteria and viruses, and allergy-causing things out of your lungs.
Breathing starts when you inhale air into your nose or mouth. It travels down the back of your throat and into your windpipe, which is divided into air passages called bronchial tubes.
As the bronchial tubes pass through your lungs, they divide into smaller air passages called bronchioles. The bronchioles end in tiny balloon-like air sacs called alveoli. Your body has about 600 million alveoli.
The alveoli are surrounded by a mesh of tiny blood vessels called capillaries. Here, oxygen from inhaled air passes into your blood.
For your lungs to perform their best, these airways need to be open. They should be free from inflammation or swelling and extra mucus.
After absorbing oxygen, blood goes to your heart. Your heart then pumps it through your body to the cells of your tissues and organs.
Make Your Own Lung Model
Clear plastic drink bottle (A Gatorade bottle is a good size)
Tape (masking tape or duct tape)
Measure an inch or two from the bottom of the plastic bottle and cut the bottom off carefully.
Take one balloon and put it inside the bottle. Then fold the bottom of the balloon around the rim of the bottle so the balloon hangs from the top. Wrap tape around the top if the balloon doesn’t seem snug around the bottle opening. You don’t want any air escaping, so make sure it is nice and tight!
Tie a knot at the end of the remaining balloon and cut the large part of the balloon in half horizontally.
Using the balloon half with the knot, stretch the open end over the bottom of the bottle. Again, this should be a tight fit. Use tape to secure if necessary.
Gently pull down on the balloon from the knot. This should cause air to flow into the balloons within your lung model.
Release the balloon with the knot and watch as the air is expelled from your lung model.
