Respiratory System
Diseases and Disorders
Tonsillitis
Inflammation of the tonsils (tonsils are lymph tissue on the side and in the back of the throat)
Sinusitis
Inflammation of the sinuses resulting from some kind of infection
Bronchitis
Inflammation of the bronchi resulting from infection
Persistent and irritating cough yielding sputum, a tight chest, wheezing, pain with cough
Whooping Cough (pertussis)
Intense bouts of coughing that interferes with breathing and can cause vomiting. Can lead to complications that can be life threatening
Pneumonia
Inflammation that causes the alveoli to fill with fluid
Pneumothorax (collapsed lung)
Air enters the pleural cavity (space surrounding the lung) and causes the lung to collapse
Pneumothorax
Tuberculosis
Infectious disease that attacks the lungsCauses severe coughing, bloody
sputum, fever, night sweats, weight loss50% of patients with advance symptoms
die from disease
Asthma
Estimated 300 million people worldwide suffer from asthma
Main Causes of AsthmaAirway constriction Inflammation
Types of Asthma1.1. Allergic Asthma Allergic Asthma – triggered by an allergic
reaction to allergens (like pollen or pet dander)
2.2. Nonallergic Asthma Nonallergic Asthma – triggered by substances in the air (tobacco, smoke, deodorizers, paint fumes, perfumes, odors)
Asthma
Types of Asthma3.3. NocturnalNocturnal – Symptoms that seem worse
in the middle of the night
4.4. PregnancyPregnancy – among pregnant patients who have asthma, 1/3 will improve, 1/3 will remain stable, and 1/3 will experience worsening of asthma
5.5. OccupationalOccupational- caused by exposure to a substance in the workplace
Asthma
911: The Bronx – Severe Asthma
Lung Cancer
Disease of uncontrolled cell growth in the lungs
Most common cause is long term exposure to tobacco smoke
15% of cases are in nonsmokers
The main respiratory consequences of smoking marijuana regularly (one joint a day) are pulmonary infections and
respiratory cancer.
The effects also include:• chronic bronchitis• impairment in the function of the smaller air passages• inflammation of the lung• the development of potentially pre-cancerous abnormalities in the bronchial lining and lungs • a reduction in the capabilities of many defensive mechanisms within the lungs.
•Marijuana smoke and cigarette smoke contain many of the same toxins, including one which has been identified as a key factor in the promotion of lung cancer.
•This toxin is found in the tar phase of both, and it should be noted
that one joint has four times more tar than a cigarette, which means that the lungs are exposed four-fold to this toxin and others in the tar.
•It is notable that several reports indicate an unexpectedly large proportion of marijuana users among cases of lung cancer and cancers of the
oral cavity, pharynx, and larynx.

Marijuana
Research has shown that marijuana’s adverse impact on learning and memory can last for days or weeks after the acute effects of the drug wear off. As a result, someone who smokes marijuana every day may be functioning at a suboptimal intellectual level all of the time.
Marijuana
A number of studies have shown an association between chronic marijuana use and increased rates of anxiety, depression, suicidal ideation, and schizophrenia.
Marijuana side effects
The Heart. One study found that the risk of heart attack more than quadruples in the first hour after smoking marijuana. This might be from marijuana’s effects on blood pressure and heart rate (it increases both) and reduced oxygen-carrying capacity of blood.
Marijuana side effects
The Lungs. same respiratory problems as tobacco smokers
daily cough and phlegm production, more frequent acute chest illness, a heightened risk of lung infections, greater tendency toward obstructed airways
Numerous studies have shown marijuana smoke to contain carcinogens and to be an irritant to the lungs.
In fact, marijuana smoke contains 50 to 70 percent more carcinogenic hydrocarbons than tobacco smoke.
Marijuana users usually inhale more deeply and hold their breath longer than tobacco smokers do, which further increases the lungs’ exposure to carcinogenic smoke
Marijuana side effects
Head and Neck. Smoking marijuana has been linked with an increased risk of head and neck cancers. Several case reports have found an unexpectedly high number of marijuana users among persons with cancers of the head and neck region, including the mouth, tongue, throat, and larynx
