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)

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.

Respiratory system  The human respiratory is a group of organs and tissues that enables your body to breathe. Its primary function is to supply oxygen to all the parts of your body.  The respiratory system is made up of airways (your nose, mouth, voice box, windpipe and bronchial tubes) and the lungs and the muscles and blood vessels connected to them.  The lungs exchange gasses and when you inhale you breath the alveoli exchanges gasses so oxygen comes in and pushes carbon dioxide out and that causes you to breathe.

Healthy vs unhealthy  Healthy- your cells are fully functioning. Then they exchange gasses properly. Which makes you able to breath. And that makes you live. A healthy respiratory system is really important because it causes you to breath/live.  unhealthy- your cells are dying and aren't functioning properly. When that happens your lungs and other organs to not function properly. If that happens it can cause other systems to shut down. And possibly kill the body. Because what happens is your alveoli's get plugged up from your own body fluid helps the infected area so that fluid in the alveoli’s fills up and causes your lungs to not exchanges gasses properly so it slows your breathing
