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

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
