Transcript of REDO Asthma

A&P II
Project By: Kate Brumley ASTHMA . Introduction:
Asthma is a condition that affects the air passages of the lungs, and makes inhaling oxygen harder or impossible. A. Asthma is a chronic condition. B. Asthma affects all ages, most commonly starts in childhood C. Asthma is not contagious D. No cure for asthma, but there are several treatments and trigger controls The word asthma is derived from the Greek word 'aazein', which means 'sharp breath'. Hippocrates, the Greek physician, first used it to describe the medical condition, around 450 BC by pointing out the symptoms of the disease, including spasms. HISTORY LUNGS
The organs of the body that are used to filter air and hold the oxygen that supply the body with ATP. Inside the lungs is a filtering system called the Bronchial Tree. A.
Oxygen is normally inhaled from the nose, where it is moistened and warmed. B.
Oxygen then passes through a windpipe called the Trachea. C.
The trachea divides into two large bronchi called the Right Bronchus and the Left Bronchus. d.Those split into smaller bronchi inside the lungs called
Lobar Bronchi
and Tertiary Bronchi e.The smaller bronchi lead to even smaller tubes called bronchioles, more specifically Intralobular, Terminal and Respiratory bronchioles When a person has asthma, the air passages are inflamed or swollen.Inflammation of the air passages makes them extremely sensitive to a number of different things that can "trigger” asthma symptoms. a. When the inflamed air passages are triggered by something in the air, the passages become narrower, which makes it difficult for the person to breathe. Muscles Lining Mucous Oxygen is a gas that is needed to sustain life. Oxygen is inhaled and gives the body the ATP, or energy, that is needed to keep a body functioning. a.Oxygen is produced by plants in the surrounding atmosphere. c. Oxygen is inhaled because of a drop in the Atmospheric Pressure, 760 mmHg, so the body can filter the air and get the ATP that is needed. c. Allergic asthma is most common in children and adolescents. An asthma attack or episode occurs when a person comes into contact with something to which he or she has developed an allergy. d.Nonallergic asthma - This type of asthma is most common in middle-aged adults. Asthma attacks may occur in response to triggers such as exercise, cold air, or respiratory infections. b. When oxygen is inhaled it travels through the Bronchial Tree to be filtered. b.All asthma is not the same, the concept of what happens to the air passages during an attack is the same but not what triggers an attack. Causes
The exact cause of asthma is not known. Researchers think some genetic and environmental factors interact to cause asthma, most often early in life. a.An inherited tendency to develop allergies, called atopy. b.One or both of the parents having asthma c.Specific respiratory infections as a child. Asthma has symptoms that could also be confused with other common sicknesses; individuals are cautioned to be sure that things such as a cough are not caused by a different infection. a.Wheezing is the most characteristic symptom of asthma, but it is important to know that other diseases, specifically during infancy can develop wheezing. b. A persistent cough at night and cough during exercise are two clear examples of an asthmatic cough. Know that a cough is a very frequent symptom during infancy and childhood. c.Chest tightness, this may feel like something is squeezing or sitting on your chest. d. Shortness of breath, some people who have asthma say they can't catch their breath or they feel out of breath. Treatment
There are different types of treatment that can reduce asthma attacks and help treat the symptoms but there is no medicine to cure asthma. a. Medication is the most common way to reduce, or prevent asthma attacks. There are a variety of asthma inhalers available to help relieve or control asthma symptoms in adults and in children. b. A way to prevent Nonallergic asthma is for the person to not participate in vigorous exercise and to stay warm during the winter to prevent inhalation of cold air. There are several different things that could cause a person to have asthma, but it does not mean that everyone will get it. Asthma is a respiratory disease that can be fatal depending on the severity of the attack. Conclusion a. This respiratory disease can affect people at any age, from infants to grown adults b.Asthma is different in everyone, someone may go months without using an inhaler while others cannot go one hour with out their inhaler. c.Symptoms worsen or get better from person to person.
