limit the ability to breathe over time, caused by a person’s genes. Cystic fibrosis is caused by mutations in a gene. It causes a thick buildup of mucus in the lungs and clogs the airway and traps bacteria leading to infections, lung damage, and eventually respiratory failure. As the mucus builds up it blocks the lungs airway. In the pancreas, the mucus prevents digestive enzymes to be released, which is used to break down food and absorb vital nutrients. Symptoms of cystic fibrosis can occur during
but not many actually know what it all entails. The article “About Cystic Fibrosis,” describes it as, “a progressive, genetic disease that causes persistent lung infections and limits the ability to breathe over time” (n.d.). This causes thick mucus buildup not only in the lungs but also in other organs as well such as the pancreas. Because of this build up, bacteria becomes trapped in the patients’ airways, which leads to infections, lung damage, and can even cause respiratory failure. The
occurs with COPD as the airways become more inflamed via the immune and inflammatory responses, smooth bronchial muscles contract, and congestion with increased mucus production causes turbulent airflow. This turbulent airflow will be heard on exhalation because of the narrowed and mucus logged airways (Mitchell, 2015). The increased mucus production occurs when inflammation causes hypertrophy and hyperplasia of the goblet cells (Brashier & Kodgule, 2012). 2. The feeling of fullness in the abdomen
lungs’ ability to secrete mucus properly. It’s gene and protein product cause the body to produce unusually thick and sticky mucus (CFF). Mucus is designed to lubricate the lungs, but the lungs of a patient with cystic fibrosis are prone to infection because of the thick mucus that traps bacteria and foreign materials. Instead of being expelled, the materials stay in the lungs and cause infections. The white blood cells die and create an even thicker substance. The mucus in the sinus cavities can
fibrosis is a genetic disorder where abnormal amounts of mucus build up in many of the body’s organs especially the lungs and the pancreas. This build up of mucus in the lungs can lead to many persistent infections that can lead to damage and scarring over time. In addition, when this mucus collects in the gastrointestinal tract and around the pancreas it prevents digestive juices from aiding in the digestion process. In addition, this mucus buildup also prevents the production of insulin, a crucial
Cystic fibrosis (CF) is a disease that is caused by a defective gene that is inherited from both parents. The defective gene causes a person’s body to release thick sticky mucus which subsequently causes the patient’s airways to be blocked. Cystic fibrosis is a chronic respiratory disease with typical symptoms being digestion, wheezing, lung infection, stuffy nose, and a persistent cough. In 1938 an American Pathologist, Dr. Dorothy Anderson, was the first to identify and document cystic fibrosis
Corticosteroids The main pharmaceutical drugs used to treat and manage asthma are Beta2-adrenergic agonist and inhaled corticosteroids (ICS). Beta2-adrenergic agonists are used for relief and acute symptoms, while corticosteroids are to be taken daily to control inflammation. Inhaled corticosteroids are used as the first-line maintenance therapy. ICS are the most effective anti-inflammatory drug used in the management of asthma. ICS must be used long-term, as symptoms are likely to recur if they
Cystic Fibrosis is a chronic non-gender biased illness which affects the digestive system and the lungs. This condition also results in the buildup of mucus, which clogs in the respiratory system as well as the pancreas. Cystic Fibrosis occurs because a defective gene causes the body to excrete excessive sticky and thick mucus that clogs the lungs leading to a life-limiting lung infections. When these thick secretions obstruct the pancreas, they prevent the digestive enzymes from reaching the intestines
In people who have CF, the gene makes a protein that doesn't work well.” When diagnosed with CF, it causes “thick, sticky mucus and very salty sweat.” More than 10 million Americans are carriers of the gene; however, there are over 1,800 mutations of the gene that have different effects on each person. “Disease-causing” are the gene mutations that cause CF. To be diagnosed
the lungs. “Dirty particles are partly cleaned by the hairs in the nostrils, and located in the airways are glands which produce sticky fluid called mucus” (UF 2015 URL). This mucus hides the airway by trapping dirt and germs found in it, the tiny broom-like structures called the cilia, clears the dirty mucus from the airways. This sweeps the mucus up near the throat where it can be spit out. Hydration also plays an important role in the lungs. If the air breathe in is too dry, it can damage the
Poiseuille’s law states the volume in a tube is directly proportional to pressure difference between both ends of the tube and inversely related to the length. Poiseuille’s law was discovered by Jean Louis Marie Poiseuille in 1840 (Poiseuille’s). Jean Louis used his experiments to find the smooth, laminar flow in circular tubing (Jean-Louis). His findings can be described as the flow of blood through the body and bronchial smooth muscle. When the resistance of a fluid increases, the flow will decrease
airways could get blocked when the muscles surrounding the lungs tighten. This keeps air from circulating freely in the lungs. Or, mucus may clog and narrow the airways in the lungs, making breathing even more difficult. During an asthma attack, the walls of the airways become irate, and the mucous membrane found on the walls of the lungs become swollen with fluid and mucus fills taking up the remaining space, making it difficult to breathe. *Because air cannot flow in and out of the lungs freely, a
Bordetella pertussis "Whooping Cough" Encounter and Colonization Bordetella pertussis is a highly communicable agent and is transmitted person-to-person via airborne droplets or direct contact with discharges from the respiratory mucous membranes of an infected person. This small, gram-negative coccobacillus is non-motile, aerobic and fastidious. B. pertussis colonizes the respiratory tract including the mouth, nose, throat and beginning of the lungs of young children worldwide. The bacteria
3. Physiology and Anatomy of Nose: 3.1 Nasal Anatomy: The human nose is the most protruding part of the face which extends approximately 3-5 cm in height externally and 10 cm long nasal cavity internally (Sforza, Grandi, De Menezes, Tartaglia, & Ferrario, 2011). Human nasal cavity starts from external nares (nostrils) to the nasopharynx (the upper section of the throat) which is equally divided by the nasal septum into 2 similar non-connected halves i.e., left- and right-nasal cavity. Anatomically

This is a bad sign for health because it “dehydrates the nasal cavities, generating more mucus inside membranes” (Rutgers, 2010). The overuse of the nasal spray might cause addiction to it. Because of the same effects that the chemicals are producing inside the nose, the body starts to be dependent on the drug, which can cause the effectiveness

The nose is divided into the right and left cavities and is lined with tiny hairs and mucous membrane, which secretes a sticky fluid, called mucus, which helps prevent dust and bacteria from entering the lungs. The nose moistens, warms and filters the air and is an organ, which senses smell. The naso-pharynx is the upper part of the nasal cavity behind the nose, and is lined with mucous

inflammation is how the body reacts to something that is irritating the airways. When happening your lungs begin swelling, your breathing passageway becomes restricted and mucus is secreted. Bronchial restriction happens when the muscles in your airways tighten around the breathing tubes in your lungs. (Bronchial tubes). Mucus or fluid that is accumulated by the reaction can obstruct your airway and make it very difficult to breathe properly. Asthma in children limits their physical activities.
Introduction: Chronic obstructive pulmonary disease (COPD) is preventable disease that has a detrimental effects on both the airway and lung parenchyma (Nazir & Erbland, 2009). COPD categorises emphysema and chronic bronchitis, both of which are characterised by a reduced maximum expiratory flow and slow but forced emptying of the lungs (Jeffery 1998). The disease has the one of the highest number of fatalities in the developed world due to the ever increasing amount of tobacco smokers and is associated
INTRODUCTION Frog is one of the animals which live on the land and in the fresh water. Frogs are distinguished from other reptiles and fishes by their specific features. Generally, frogs are categorised in kingdom of Animalia, phylum of Chordata, subphylum of Vertebrata, class of Amphibia, order of Anura and family of Ranidae (Amsel, 2014). The common species of frog found is Rana tigrina. Frog is actually one of the poikilotherms animals or known as cold blooded animals. Frogs do not have constant
