Human lung

In the human body lies an organ that can float on water the lungs. In that organ there is a cell called Alveoli. The major thing the Alveoli does is take air. The Alveoli can be deeply affected by Lung Cancer. Lung Cancer can kill the alveoli cell and cause death. The alveoli cell is apart of the respiratory system. The respiratory system includes the mouth, nose, throat, lungs, and more. It takes in oxygen either through the nose or mouth and removes the carbon dioxide, this is also called…

They are also used for short and long term relief of certain symptoms that come with COPD. ” Studies show that inhaled beta2-agonists are effective in treating symptoms of COPD and improving lung function as measured by tests (spirometry). They also reduce the number of COPD exacerbations (Celli, 2008). The preferred use of β2 agonists are through inhalation because they cause the smooth muscle relaxation. “Long-acting bronchodilators are preferred…

Asthma is a chronic disorder of the airway characterized by ongoing inflammation of the airway, in which the flow of exhaled air from the lungs may be restricted due to inflammation. Airway inflammation stems from a variety of stimuli such as the presence of inflammatory cells, damage to the bronchial epithelium, cytokines, genetic predisposition from the development of an IgE and/or viral…

Review Keishera Aldonza Candidate for Bachelor, Department of Medical Laboratory Sciences at University of Massachusetts Dartmouth Introduction Preterm infants often display signs of respiratory distress syndrome at birth due to the immaturity of the lung structure, with respiratory morbidity decreasing as gestational age increases. Respiratory distress syndrome is caused by a deficiency of surfactants. Surfactants, a lipoprotein complex, function by decreasing the surface tension of the fluid…

Croup is an acute infectious laryngotracheitis which occurs mostly in children less than six years of age(although the peak incidence is around two years). It is characterized by a barking cough, hoarse voice and respiratory difficulties, which are typically seen to occur at night. Symptoms of croup Croup usually begins as an ordinary cold with symptoms such as a runny nose, slight rise of temperature and a mild cough. Within a week, a child with croup develops a barking cough with noisy…

Silicos disease form part of the lung disorder known as pneumoconioses and is characterized by nodules and fibrous scar tissue within the lungs. It is often caused by inhaling silica particles from the quartz in rocks, sand and similar other substances. These particles gets entrapped in the alveoli and macrophages that are present in the alveoli consumes the silica particles and died with the resulting inflammation attracting more macrophages, resulting into the formation of nodules and fibrous…

Chronic diseases of respiratory system are the fourth leading cause of death in the United States. They affect airways and lung function, one common obstructive lung disease is asthma. According to CDC.gov about 17.8 million adults and 6.8 million children are suffering from asthma [9]. According to world health organization estimates, 235 million people suffer from asthma worldwide [10]. Asthma disease doesn’t have obvious symptoms which makes it hard to diagnose, so major component of chronic…

Introduction Acute bronchospasm caused by asthma is also referred to as an asthma attack. Bronchospasm means your air passages become narrowed. The narrowing is caused by inflammation and tightening of the muscles in the air tubes (bronchi) in your lungs. This can make it hard to breathe and cause you to cough or breathe loudly (wheeze). What are the causes? Possible triggers include: Animal dander from the skin, hair, or feathers of animals. Dust mites contained in house dust. Cockroaches.…

For many years, open-heart surgery has been the sole option when it comes to valvereplacements in the heart. Today, with the help of fluoroscopy, a non-surgical approach has beenevolving and is changing the face of medicine. Transcatheter Valve Replacement (TVR), is apercutaneous technique that uses fluoroscopic guidance to replace a diseased or dysfunctionalvalve without ever having to go under the knife. To be able to intervene percutaneously is the“most exciting advancement in the treatment…

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.…
