The Respiratory System By: Kristin Greene
to supply the blood with oxygen so the blood can deliver oxygen to all the body parts
The process of respiration
“ Respiration is achieved through the mouth, nose, trachea, lungs, and diaphragm. Oxygen enters the respiratory system through the mouth and the nose. The oxygen then passes through the larynx and the trachea which is a tube that enters the chest cavity.
In the chest cavity, the trachea splits into two smaller tubes called the bronchi. Each bronchus then divides again forming the bronchial tubes. The bronchial tubes lead directly into the lungs where they divide into many smaller tubes which connect to tiny sacs called alveoli. The average adult's lungs contain about 300 million of these spongy, air-filled sacs that are surrounded by capillaries.
The inhaled oxygen passes into the alveoli and then diffuses through the capillaries into the arterial blood. Meanwhile, the waste-rich blood from the veins releases its carbon dioxide into the alveoli. The carbon dioxide follows the same path out of the lungs when you exhale.”
The Respiratory system includes…
The main organs of the respiratory system are the Lungs
Yawning brings more air to the lungs
We breath 13 pints a minute
we breath over 5000 times a day
Your right lung has 3 lobes while the left lung only has 2
The speed of a sneeze over a 100 mph and a cough is only 60 mph
Lung cancer is the most common cancer in the world
Asthma is a chronic (long-term) disease that makes it hard to breathe. Asthma can't be cured, but it can be managed. With proper treatment, people with asthma can lead normal, active lives.
How asthma works
If you have asthma, your airways (breathing passages) are extra sensitive. When you are around certain things, your extra-sensitive airways can:
Become red and swollen - your airways get inflamed inside. They fill up with mucus. The swelling and mucus make your airways narrower, so it's harder for the air to pass through.
Become "twitchy" and go into spasm - the muscles around your airways squeeze together and tighten. This makes your airways narrower, leaving less room for the air to pass through.
The more red and swollen your airways are, the more twitchy they become.
Hard breathing caused by irritants
Asthma inducers : If you breathe in something you're allergic to- for example, dust or pollen- or if you have a viral infection- for example, a cold or the flu- your airways can become inflamed (red and swollen).
Asthma triggers : If you breathe in an asthma trigger like cold air or smoke, or if you exercise, the muscles around your airways can go into spasm and squeeze together tightly. This leaves less room for air to pass through.
It's important for every person with asthma to know what they triggers and inducers are.
Normal Swelled Asthma Tightened Asthma
Work-related asthma (occupational exposure) : People who work in certain types of jobs can get asthma from things they work with. For example:
Laboratory workers can get asthma from lab animals: rats, mice, guinea-pigs
Spray painters can get asthma from isocyanates
Grain handlers can get asthma from grain dust
Crab processors can get asthma from crab dust
These devices (sometimes called 'puffers') contain a gas that will propel the correct dose of medication when the top is pressed down. This is inhaled into your airways. There are two basic categories of inhaler medicines that are used for asthma:
relievers - which treat your symptoms
preventers - which can prevent your symptoms
In case of an attack
take your reliever treatment immediately, preferably with a spacer
sit down (don't lie down) and try to relax
wait 5-10 minutes - if your symptoms disappear you do not need to do anything
if your symptoms do not go away, then you should call a doctor or an ambulance
continue taking your reliever, preferably with a spacer, every few minutes until helps arrives
If you go to hospital, take details of your asthma treatments with you.
Tuberculosis Danielle Mullins Summer Institute 2oo6
What is it?
caused by bacillus Mycobacterium tuberculosis
spreads person to person or through air
most are infected but do not develop the disease
form small black lesions in the lungs
loss of weight
loss of appetite
coughing up blood
2 million deaths each year; 100 thousand are children. 36 million will die worldwide between now and 2020. Most cases found in Africa due to the AIDS epidemic. 10 million Americans are currently infected with TB but only 10% will develop the disease.
Persons Most Likely to Contract TB
Hospital, prison, and nursing home workers
IV drug users
Those with Diabetes, AIDS, or others with immunity problems
A Person with: Latent TB Active TB
has no symptoms
does not feel sick
cannot spread TB
Usually positive for skin test
has normal chest X-ray and sputum test
continuous bad cough
coughing up blood or sputum
weakness or fatigue
loss of weight and appetite
chills, fever, night sweats
positive skin test
may have abnormal chest X-ray, or positive sputum smear or culture
Random Facts 53% of last year's TB cases were foreign-born people 1/3 of the world population is infected with TB TB can usually be cured but medication must be taken for up to 9 months Someone somewhere in the world is infected with TB every second India has the largest number of TB patients today.
Your lungs help you to breath. Take a big breathe and you will make your lungs work really hard. Lungs help you to breathe in nice clean air. And breathe out old air. Blood is a really bright red liquid. It runs around your body, helping it to work properly. It also helps stop some nasty bugs
Your brain like a big grey jelly. It’s all spongy.
Your eyes help you to see everything.
They make these into something your brain can understand
When you eat some food, it goes into your digestive system.
This is where your food is turned into something your body can use.
Your lungs help you to breath.
Lungs help you to breathe in nice clean air and breathe out old air.
