THE RESPIRATORY SYSTEM
By: Carter Paquette, Ethan Eldridge, Brendan Marusiak, Nik Brading
The Structure Trachea- Tracheal rings (tracheal cartilages). Bronchi- Bronchi are air tubes that spring out like roots into the
lungs and transport air. Mouth/Nose- Both are passages that allow air to enter the lungs
and circulate the air. Lungs- Are sponge like organs filled with air. Diaphragm- Is the muscular structure that expands the cavity. Pharynx- is a tubular structure placed behind the oral and nasal
cavity. Larynx- Is made of bone like cartilages.
The Roles of each Organ Lungs- provides oxygen to capillaries so they can oxygenate blood. Bronchi- are the 2 main airways to the lungs. Allows the air into the
lungs through the nose or mouth. Diaphragm- is the main muscle used to process the inspiration or
breathing in. Trachea- known as the wind pipe. Mouth/Nose- are the main access passages to the lungs to
transport air. Pharynx- is a tubular structure placed behind the oral and nasal
cavity. Larynx- from the pharynx, air enters the larynx, part of the upper
respiratory tract.
How does the respiratory system react to a stimuli? If the heart rate changes drastically the amount of
oxygenated blood will increase to keep your muscles moving.
When exercising your adrenal gland produces adrenaline and noradrenaline that directly affects the heart and the ability to transport oxygen and carbon dioxide throughout the body.
When you are scared the adrenal gland does the same thing, releases adrenaline and noradrenaline (reaction) to make your heart beat faster then the oxygenated blood gets to your muscles faster than normal and that makes you react to a scare (stimuli)

RESPIRATORY SYSTEM: COMMON
DISEASES
By Nik
Asthma
The airways are persistently inflamed, and may occasionally spasm, causing wheezing and shortness of breath.
Symptoms: Wheezing Coughing that won't stop Shortness of breath Tightness in the chest In severe cases, an untreated asthma
attack can be life-threatening.
Allergies
infections or pollution can trigger asthma's symptoms.
The airways are persistently inflamed, and may occasionally spasm, causing wheezing and shortness of breath.
COPD Chronic obstructive pulmonary disease COPD: Blocks the
airway and makes it difficult to exhale air. Symptoms: Inside the lungs, COPD can clog the airways
and damage the tiny, balloon-like sacs (alveoli) that absorb oxygen. These changes can cause the following symptoms:
Shortness of breath in everyday activities Wheezing Chest tightness Constant coughing Producing a lot of mucus (sputum) Feeling tired Frequent colds or flu
Chronic bronchitis
Chronic bronchitis: A form of COPD characterized by a chronic productive cough.
Emphysema
Lung damage allows air to be trapped in the lungs in this form of COPD. Difficulty blowing air out is its hallmark.
Acute bronchitis
Acute bronchitis: A sudden infection of the airways, usually by a virus.
Cystic fibrosis
A genetic condition causing poor clearance of mucus from the bronchi. The accumulated mucus results in repeated lung infections.
