Transcript of Respiratory system prezi

THE RESPIRATORY SYSTEM
The purpose of the Respiratory system is to supply blood and oxygen, so that the blood can give oxygen to all parts of the body, and the Respiratory system can do this through breathing.
What is the purpose of the Respiratory system?
Each of the pair of organs situated within the rib cage, consisting of elastic sacs with branching passages into which air is drawn, so that oxygen can pass into the blood and carbon dioxide be removed. Lungs are characteristics of vertebrates other than fish, though similar structures are present in some other animal groups.
Lungs
Trachea ( windpipe )
The membrane-lined cavity behind the nose and the mouth, connecting them to the esophagus.
Pharynx ( throat )
A large membranous tube reinforced by rings of cartilage, that helps you breath and leads right to the stomach.
Vocal Cords
Folds of membranous tissue that project inward from the sides of the Throat.
Nasal Passage
Epiglottis
A flap of cartilage at the root of the tongue which is suppressed during swallowing to cover the opening of the windpipe.
A channel for air flow through the nose. The mucous inside the nose catches all the dust and germs . The nose hairs filter the air so we can breathe clean air .
Larynx
The Larynx is a hollow muscular organ forming a passage to the lungs holding the vocal cords in a human.
Diaphragm
A dome shaped muscular portion separating the thorax from the abdomen in mammals. It plays a major role in breathing. Also increases the volume of the thorax and inflates the lungs.
Bronchi
Any of the major air passages of the lungs that come from the windpipe . It's main function is to carry air from the trachea to the lungs
Alveoli
Any of the many tiny air sacs in the lungs where the carbon dioxide and oxygen exchange takes place .
Pneumonia
Pneumonia is a infection that irritates and inflames the air sacs in lungs . This can occur in one lung or both . When both lungs are affected they both fill up with fluid , and this is called Double Pneumonia . Also , when certain lobes are affected it is called Lobar Pneumonia .
Chronic Bronchitis
Chronic Bronchitis is a regularly happening inflammation of the mucous membrane . This inflammation occurs in the bronchial tubes , and causes coughing .
Emphysema
Emphysema is a condition that causes breathlessness because the air sacs in the lungs are damaged , and enlarged .
Homeostasis
This is when body seeks a balance in its environment ( equilibrium ) , even with external environmental changes .
Cellular Respiration
This is what cells produce energy . They do this by breaking down sugars , and turning it into energy the cell can use . Cells take in food and uses it to create ATP a chemical the cell uses for energy . All forms of life use Cellular Respiration .
Gas Exchange Process
Oxygen and Carbon Dioxide (a waste product of body processes) in which air is exchanged in air sacs in the lungs (alveoli) at the end of the bronchial tubes . The alveoli in the lungs are surrounded by capillaries .
What would happen if food were caught in the trachea , and what can be done to help ?
When you chew thirty muscles in the throat spring into action without you knowing , which lets you eat your food . If you accidentally swallow your food down the wrong pipe the food is going into the trachea , and can become lodged in the throat . This chokes you triggering you to cough to remove the food from your trachea . The Heimlich Maneuver can be used to help .
Heimlich Maneuver
This is a first aid procedure used to dislogde objects caught in the windpipe . When doing this you will apply a strong pressure on the abdomen between the navel , and the ribcage .
How the Respiratory System works with other systems ....
The Respiratory system works with the ...

Circulatory System because this system protects the lungs
Digestive System by breaking down food into nutrients the lungs need to function
Health Conditions Related to the Respiratory System
Hypoxia and Anoxia
a decrease of oxygen (hypoxia)
complete lack of oxygen ( anoxia )
can be fatal because four minutes without oxygen brain cells start dying , which can lead to brain damage and death
FACTS
the right lung is slightly larger than the left lung
the highest record sneeze time is 165 km per hour
the surface area of the lungs is rouge same size as a tennis court
a person normally breathes between 12 & 15 times a minute
