Document Summary

Biol chapter 22 textbook notes: internal respiration: oxygen diffuses from blood to tissue cells, and. The respiratory system is responsible for only the first two processes, but it cannot. Because it moves air, the respiratory system is also involved with the sense of. The major function of the respiratory system is to supply the body with oxygen: pulmonary ventilation: air is moved into and out of the lungs (during, external respiration: oxygen diffuses from the lungs to the blood, and. As cells use oxygen, they give off carbon dioxide, a waste product the body must. Our trillions of cells require a continuous supply of oxygen to carry out their vital. The actual use of oxygen and production of carbon dioxide by tissue cells, known functions. get rid of. They also generate dangerous free radicals, the inescapable by-products of living in a world full of oxygen. and dispose of carbon dioxide.

One of the most common chronic conditions affecting the respiratory system is asthma. Asthma is a condition characterized by inflammation of the airways. When an asthma attack is triggered, the airways become even more inflamed and can restrict breathing. Common symptoms during an asthma attacks include coughing, wheezing, tightness in the chest and shortness of breath. Severe asthma attacks can be fatal. People with a family history of asthma are more likely to have the condition. While there is no cure for asthma, proper medical care and a management plan can help to maintain quality of life for people living with asthma. There are different types of asthma, each with their own triggers and management plans. Type Description Exercise-induced Bronchoconstriction (EIB), or Exercise-induced Asthma (EIA) Some people only experience asthma symptoms during exercise. Exercise-induced asthma causes the narrowing of airways during exercise, which restricts the flow of air to and from the lungs. Cold, dry air tends to exacerbate symptoms, while warm, humid air may reduce symptoms. People with exercise-induced asthma should work with their doctor to create a management plan that still allows them to exercise while keeping their symptoms under control. Allergic Asthma Allergic asthma is the most common form of asthma. It is triggered by inhaling allergen particulates, such as dust mites, pollen, pet dander, or mold. The bodyâs reaction to the allergens causes inflammation that results in coughing, wheezing, and other symptoms of asthma. Occupational Asthma Occupational asthma is caused by the frequent inhalation (breathing) of gases, fumes, dust, or other harmful substances in the workplace. Employees working in the chemical or petroleum industries are frequently exposed to chemicals such as Sulphur dioxide or hydrochloric acid, and may develop occupational asthma after prolonged exposure. Childhood Asthma Childhood asthma is usually developed before age 5. It is a condition that affects millions of children. It is vital that childhood asthma is properly controlled to prevent damage to the developing lungs Risk factors: â¢ Allergies â¢ Family history â¢ Frequent respiratory infections â¢ Low birth-weight â¢ Second-hand smoke â¢ Residing in a low-income, urban environment

Asthma symptoms that are triggered by exposure to pollen, pet dander, mold, or dust mites is indicative of which of the following types of asthma:

Occupational asthma

Childhood asthma

Allergic asthma

Exercise-induced asthma
