airways will flare up to the simplest triggers like pollen, animal dander, dust, fumes, or poor air quality (WebMD). A second grader named Hannah Austin from Smyrna, Georgia suffers from asthma. Twice a day she has to exhale all the air from her lungs to take a puff of a low- dose steroid. She often has to struggle to catch her breath when the air quality is poor (Fortin). According to the Atlantic each state department of education makes is own length of school day, but has to fulfill the 180…

The toxin was first discovered in 1735 Europe as it caused a fatal disease of the nervous system. Its cause was suspected to be connected to German Sausages. This is originally where its name came from, as due to these suspicions the toxin was named “botulus” – the Latin for sausage. Since then we know that Botulinum Toxin is a potent neurotoxin that is produced by rod-shaped spore-forming anaerobic bacterium called Clostridium bacterium. The bacterium require special conditions to reproduce;…

According to the Centers for Disease Control and Prevention, asthma is a disease that affects your lungs. It causes repeated episodes of wheezing, breathlessness, chest tightness, and nighttime or early morning coughing. This chronic condition is when the airways that carry air to and from lungs get affected. People that are affected with this for a long time are said to be asthmatic (CDC.GOV, 2015). The inside walls of an asthmatic's airways are swollen or inflamed. This swelling or…

should read through your lecture notes on the respiratory system; the background information for this class on Moodle; and section 23-7 in Martini (2012) p830-838. Please hand your individual work into the Student Centre by the deadline. Exercise 1: Lung Volumes and Capacities The predicted values are based on the Goldman and Becklake equations for Pulmonary Function (cited from the John Hopkins Pulmonary Laboratory). 1. Comment on the differences between the experimental and…

Disease can be considered zoonotic (Diseases passed from animals to man). In a normal person, the body’s immune system quickly recognizes the parasite and destroys it. In rare instances, however, the larval heartworm manages to migrate to the person’s lungs where the dying parasite stimulates an inflammatory lesion called a “coin lesion”. There have been 100 known cases in the United…

the lungs. Located on the inner walls of the trachea are small hairs, these hairs catch dust and other contaminants from inhaling, generally through the oral cavity due to its lack of filtration, collected contaminates are later disposed of via coughing. Gas Exchange Lungs: • Bronchi- At the end of the trachea two tubes stem off of its base, each connected to a lung. The bronchi’s connection to the lungs allows air from external respiratory intakes/openings to pass, efficiently, into the lungs.…

deficiency is not a rare disease, but is one that is often underdiagnosed. Normally our lungs are protected by antiproteases because our lungs are exposed to airborne pathogens and hazardous substances. One of these antiproteases is alpha- 1 antitrypsin – which normally is at a high concentration in the lungs.…

Asthma Asthma is a chronic lung disease that irritates and narrows the respiratory airways. This lung disease is not limited to any specific age group, as it affects people of all ages, but it does begin developing in the childhood stage. Around 25 million Americans currently live with asthma, with a third of these people being children.¹ Living with this condition is a responsibility that the affected person must carry. Asthma is not considered to be a life threatening condition by most, but…

A factor contributing to Asthma is an individual’s occupation. The term ‘Occupational asthma’ can be defined when asthma is triggered because of an individual working environment. Typically, there are jobs, which involve being exposed to specific substances known as respiratory sensitizers, which could potentially causes a sickly response. If exposed for a long duration, it could possibly lead from occupational to chronic Asthma. The main examples that could cause occupational asthma is from a…

of the body it is located. An air embolism can also be cause if there has been damage to the lungs. If you are in an explosion the blast may force air into damaged arteries. Although air embolisms are extremely rare they do happen.…
