Introduction to the Respiratory System
Diagnosis and treatment
Treatment and Prevention
The End!
Importance of knowing about the respiratory system
-holding your breath while dancing could have a negative impact on a dancer's health and well being
-helps us maintain the correct breathing
-allows oxygen to get to the cells in the body
-helps the body to continuously move
Breathing patterns can be improved by enhancing your postural alignment.
Different ways to diagnose a patient with respiratory diseases:

Chest x-rays
PFT tests
How COPD is treated:

Take prescribed medication
Severe cases may require oxygen tanks
Pulmonary rehabilitation
Complementary therapies

Smokers should quit smoking
Keep a steady breathing pattern
Avoid exposure to lung irritants
Supplies the blood with oxygen in order for the blood to deliver oxygen to all parts of the body.
Functions of the Respiratory System
includes air passages, pulmonary vessels, the lungs, and breathing muscles, provides oxygenated blood to the body tissues and removes waste gases.
removes the carbon dioxide produced by cellular respiration
The Respiratory Tract
Nasal Cavity:

cleans the air, warms the air, moistens the air

where the nasal cavity, esophagus, and trachea meet

an integral part of the body's airway and has the vital function of providing air flow to and from the lungs for respiration
carries air from the trachea into the
Gas exchange of oxygen and carbon dioxide takes place
Gas Exchange
goes into the blood vessel
Carbon Dioxide:
leaves the blood vessel into the alveolus
There are many diseases that can occur in the lungs such as...
Lung Cancer

-taking air into the lungs
-diaphragm contracts and moves down
-ribs expand

-breathing air out
-diaphragm relaxes and moves up
-rib cage lowers
Chronic obstructive pulmonary disease
Rapid breathing
Acute respiratory distress syndrome
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 (where speech sounds are produced) 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.
