First, I would do a lung volume test. This test measures the volume of air in the lungs at distinct periods of the breathing cycle. It is accomplished utilizing a machine called the plethysmography. You are seated during the exam and will be asked to breathe in and out of a mouthpiece and sometimes to gasp for air (Ranu et al., 2011). The exam is specifically beneficial in distinguishing between restrictive lung diseases such as pulmonary fibrosis and obstructive lung diseases such as asthma. Secondly, I would do a maximal voluntary ventilation test (MVV). This measures the greatest quantity of air that can be breathed in and breathed out in one minute. The exam is commonly carried out greater than 15 seconds, which will require you to breathe in and out as vigorously as possible (Ranu et al., 2011). This exam can be beneficial in evaluating the overall capacity of the respiratory system. It might be diminished in cases of asthma, upper airway…

In the respiratory system the lungs are the primary organs. The diaphragm is a muscle that helps the lungs take in oxygen and take out carbon dioxide as we breathe. When air enters our body it goes down the trachea which then branch off into tubes that carry the air inside the lungs. While the air is in the lungs it inflates air sacs called alveoli. When the oxygen passes the walls of the alveoli it goes into the blood vessels which carries the oxygen through out the body to use as needed.…

which aggregate to form a clot of cells called a tumor. These tumors create hindrance in the proper functioning of the organ in which they originated. Cancers are leading causes of deaths now a days, because of the few treatment options available. Lung cancer is obviously the tumor in the lungs- the respiratory organs of the body. Cancer is a disease that can spread to other organs and interfere with the functioning of those organs as well. This is the reason that complicates the study of…

The total lung capacity refers to the maximum amount of air a person’s lungs can hold (wisegeek.org, 2014). Breathing occurs in a cyclic manner due to the movements of the chest wall and the lungs. The resulting changes in pressure, causing changes in lung volume and lung capacity (humanphysiology.hubpages.com, 2014). An average human’s lung capacity can hold 4-6 liters, but only ⅓ of your lung capacity is used during normal activity, but this fraction increases during strenuous activity when…

Experiment 14.1 The Histology of the Lung Introduction: This experiment will give you a change to see an alveolus, a capillary, and the respiratory membrane. Procedure: I studied a slide of a lung tissue and observed the various structures, mainly the alveoli, capillaries, and the respiratory membrane. I then drew pictures of the structures in different microscope powers. Summary: Very briefly, we will discuss how air travels to the lungs. First, air travels down your larynx, and then into…

Introduction: When we talk about lung cancer we automatically think of smoking, and not the history behind it. Normal lung tissue are made up of cells that are arranged by genes to create lung tissue in a certain shape to perform certain tasks. Lung cancer forms by out of control growth of abnormal cells in the lung. Lung cancer transpire when the genetic material responsible for production of lung cells are damaged. There are two main types of lung cancers; small cell and non-small cell lung…

Asthma is a chronic (lifelong) lung disease that makes it harder to move air in and out of your lungs. With asthma, your airways' lining tends to always be in a hypersensitive state characterized by redness and swelling (inflammation). It's similar to how your skin becomes red, irritated and sensitive after a sunburn. With asthma, the airways in your lungs are often swollen or inflamed. This makes them extra sensitive to things that you are exposed to in the environment every day. When you have…

Lung Cancer Cancer, including lung cancer, can strike at any moment, no matter your lifestyle choices. Because of this, lung cancer is considered to be the second most common type of cancer among men and women worldwide. It is also most often present as an aggressive cancer which causes it to have a mortality rate of 86 percent (“Lung cancer, small cell.”). This is why men and women alike should be extremely cautious about what they surround themselves with. Even if you have never picked up…

acute dynamic lung hyperinflation, dyspnea is increasingly implicated as the primary symptom causes exercise limitation and skeletal muscle deconditioning as a result of avoidance activity. Hyperinflation, refers to an increase in lung volume above the resting volume due to air trapping, is the crucial consequence of mechanical restriction of this…

Lung cancer claims more lives in the United States than any other type of cancer. According to the Centers for Disease Control and Prevention (CDC), lung cancer is the leading cause of cancer death and second most diagnosed cancer in men and women in the United States (CDC, 2014). Cigarette smoking is considered the number one cause of lung cancer (CDC, 2014). The rise and fall of cigarette smoking in the United States has greatly impacted the direction we see lung cancer rates moving in. Lung…
