Nasal Cavity Research Paper

“Obtaining oxygen and removing carbon dioxide are the primary functions of the respiratory system, which includes tubes that filter incoming air and transport air into and out of the lungs as well as microscopic air sacs where gases are exchanged” (Moini, 2013, p.497). Our respiratory system is broken down into two sections known as the upper respiratory tract and the lower respiratory tract.

The nose has two nostrils that provide an opening through which air can enter and leave the nasal cavity. There are many hairs in the opening to help prevent the entry of large particles that are in the air.

There are numerous different challenges that the paramedic will face in attempting to keep an airway patent. These challenges vary from patient to patient depending on their condition. One challenge in keeping a patent airway the paramedic will face is trying to maintain the airway of a trauma patient. Trauma patients make it difficult to maintain an airway due to the traumatic damage, especially if it has affected the face and neck regions.

The respiratory system is made up of organs and tissues that help you breathe. The main parts of this system are the lungs, the trachea, the diaphragm, alveoli and nasal cavity. The respiratory system starts with the mouth and the nose, where air is brought in, then passes through the larynx and the trachea into the chest cavity. http://www.nhlbi.nih.gov/health/ health-topics/topics/hlw/system The main organs of the respiratory system are lungs, which carry out this exchange of gases as we breathe. The

➢ Inhaled air enters the nasal cavity, where it is cleaned, warmed and humidified on its way through the pharynx.

Diaphragm a) The functions of the nose are to moisten and warm inhaled air before it enters the lungs, to filter and remove dust and particles and plays a key role in our sense of smell. () During inhalation air enter the nose at a temperature that is too cold. The large surface area of the nose, (provided by the turbinates, which divide into four, grooved airways) means that the air can be warmed, as it travels through the nose in a regular and steady manner again due to the turbinates. The nose has many blood vessels near its inner surfaces and these also help to warm the blood. ()

Air (oxygen) is inhaled into the body by the nose. The air is warmed filtered and moistured in the nasal cavity as the air needs to be cleaned before passing it along to the pharynx. Mucous is held in the sinus cavity. With the joint help from the mucous and the tiny hairs in the nose our nose ensures that the air is cleared of pathogens so that the air is clean to move on to the pharynx. The tiny hairs in the nose causes us to sneeze resulting in pathogens that may have been inhaled to be sneezed out and released back into the atmosphere.

Within the past few days, the news has been covering the story of KJ, a 52-year-old woman in Omaha, Nebraska. During a traumatic motor vehicle accident a few years ago, KJ hit her face against the dashboard and started having severe migraines and constant runny nose. Multiple doctors have seen her since, most of them blame the runny nose on allergies and attempted to treat her with numerous allergies medications. This year, KJ was being seen by physicians at Nebraska Medicine and finally discovered that her runny nose was in fact a cerebrospinal fluid (CSF) leak from her brain. KJ condition is known as CSF rhinorrhea, a rare but dangerous condition that can lead to significant morbidity and mortality for the patient. Multiple nuclear medicine imaging techniques can be used for the diagnosis of CSF rhinorrhea including Computed Tomographic (CT) Myelography and Radionuclide Cisternography.

Consist of the nasal passage, pharynx, esophagus, larynx, trachea, lungs, diaphragm, bronchi, and pulmonary artery and vein.

The respiratory system consists of the lungs and air passages. The system functions to bring in air and extract oxygen and remove carbon dioxide*. The body can hold 4 to 6 minutes worth of oxygen so the respiratory system must work at all times to prevent death. There are multiple parts to the respiratory system for example, the nose has nostrils or nares. It contains a nasal septum which divides the nose into hollow spaces called nasal cavities. The nose filters the air with the mucus produced. Also located in the nose are the olfactory receptors, and nasolacrimal ducts. The sinuses which are resonating chambers of cavities located in the skull. A larger part of the respiratory system is the pharynx also known as the throat. It is located directly behind the nasal area, divided into three parts; nasopharynx(upper portion), Oropharynx(middle portion), Laryngopharynx (lower portion). The larynx also known as the “voice box” located between the trachea and pharynx. Trachea also known as the windpipe extends from the larynx to the center of the chest; its functions to carry air between the pharynx and bronchi. The bronchi function to carry air to the lungs. The right bronchus is more vertical, shorter, and wider compared to the left.Bronchi continue to branch off into smaller bronchioles, the smallest is called terminal bronchioles which deliver air to the alveoli. 500 million alveoli, which have a rich network of capillaries needed for exchange of oxygen and CO2( taken place

Nasal polyps sound strange but they are actually fairly common. Nasal polyps are noncancerous, teardrop shaped growths that develop on the inside of your nose and around your sinuses. They are found in areas where the sinuses open up into the nasal cavity. Nasal polyps range in size and resemble peeled, seedless grapes.

For this paper, I decided to write about bronchiectasis. Bronchiectasis is a respiratory disease that takes on the appearance of cystic fibrosis. It is caused by the buildup of mucous causing the airways to stretch and widen and are irreversible. (American Lung Association, 2015) I chose to write about bronchiectasis because one of my dear friends has recently been diagnosed with this respiratory disease. Jasmine Coleman was born with a rare blood disorder and as a child she was always in and out of the hospital because she was more susceptible to infections, pneumonia was the main problem. Her condition was so severe that she wasn’t expected to have lived through high school, but she is still with us today. Over time her airways have built up with mucous and she began to cough up large amounts of blood. She had undergone various testing and treatments to try to figure out what was wrong. It was only recently when she was finally diagnosed with bronchiectasis. She has only 22 percent lung function and that is mainly in her left lung for her right lung is filled with blood. She is currently on six liters of oxygen when she is out and about and two liters for when she is resting. (Times Bulletin, 2015) She may be

Nasal polyps are small noncancerous growths that resemble peeled grapes. They range in size with nasal polyps growing large enough to obstruct the sinuses and the nasal cavity. There are many methods for treating nasal polyps from homeopathic, steroids, and surgery. Nasal polyps can be managed and often eliminated for short periods of time. Nasal polyps are irritated by severe allergy drainage and are often found in individuals that suffer from severe allergies and asthma.

Insects transport gases throughout their bodies through a system of branching tubes called tracheae which then branch off into tiny fluid lined tubes called tracheoles. Gases, oxygen and carbon dioxide, enter and exit the tracheae through paired openings called spiracles. These spiracles have filtering devices such as fine hairs, which prevent tiny particles from clogging the gas exchange system. Spiracles also consist of valves that control the degree to which the spiracles are open.

Air can be breathed in through both the nose and the naval cavity, or the mouth, also known as the oral cavity. The air, regardless of the path taken, will always lead to the pharynx, a space located at the back of throat. It will progress through the larynx,
