Respiratory tract

Aspiration – A respiratory emergency Aspiration is the introduction of solids or liquids into the lungs. The presence of any substance other than breathable air impedes the perfusion in the alveoli, while the substance itself may also have damaging properties to the lung and airway tissues. Common aspirations include water, food, vomit, foreign objects or small particulates. The first three are easily introduced by the oropharynx by some sort of misdirection into the larynx rather than the…

Pneumonia in Children Pneumonia is a serious life threatening illness in children. It is a form of Acute Respiratory Infection (ARI) that affects the lungs that are made up of small sacs called ‘Alveoli’. Hen hey get infected, these alveoli fill with pus and fluids. This makes it difficult for the baby to breathe and limits the oxygen intake. The Scary Statistics: • Pneumonia is the world’s leading killer of children under the age of five. • Each year, pneumonia takes the life of 1.4 million…

The resonatory system includes the nasal cavity and soft palate and portions of the anatomically defined respiratory and digestive systems. (Seikel, King, & Drumright, 2010). One disorder that may affect a person’s ability to use the resonatory system to produce sufficient speech is velopharyngeal insufficiency, or VPI. This is a disorder which results in the improper closure of the velopharyngeal sphincter (soft palate muscle in the mouth) during speech, allowing air to escape through the nose…

Community Acquired Pneumonia Pneumonia is an infection of the lung that involves alveoli, also known as air sacs, and is caused by various microbes including viruses, bacteria, or fungi. It is one of the leading causes of mortalities across the globe. Pneumonia commonly occurs in persons living in their home community hence the community-acquired pneumonia and also among patients who may be hospitalized for other dissimilar reasons as to pneumonia, hospital-acquire pneumonia. Up until 1930,…

day! I went inside a giant’s respiratory system and it was awesome. I entered the respiratory system from the nasal cavity. The nasal cavity is part of the respiratory system. The nose is the primary opening for the respiratory system. Have you ever wondered how it works? The term "nasal cavity" can refer to each of the two sides of the nose or to the two sides combined. The two nasal cavities condition the air to be received by the other areas of the respiratory tract. Owing to the large…

metabolic consumption and ATP production. There are limited means of oxygen storage in the tissues; as such a continuous supply of oxygen is required. The respiratory and cardiovascular systems work together to make sure oxygen is delivered throughout the body, and that these continuous requirements are met. Exploring the main role of the respiratory system in this process and its relationship with the cardiovascular system is best explained in 4 main steps. 1. “Uptake in the lungs 2. Carrying…

Respiratory Syncytial Virus – RSV Anatomical & Physiological Influences Causes RSV more frequently effects infants but can affect adults. Infants who have had RSV have an increase frequency of wheezing. Air enters the respiratory tract through the nose or mouth and then either enters the nasopharynx, or oropharynx respectively. Continuing through the laryngopharynx to trachea, which divides at the carina to form the left and right main bronchus. In each lung the bronchus divide into the…

environment to the cells in the body. Biochemistry defines respiration as the metabolic process by which cells utilize glucose and oxygen to produce Adenosine Triphosphate (ATP). Inspiration, which is an active part of respiration, is initiated by the respiratory control center in medulla oblongata. Nerve impulses from medulla oblongata causes diaphragm and the external intercostal muscles to contract, which leads to the expansion of the thoracic cavity. According…

The Respiratory System’s Vital Role in the Human Body Lakessia Dumas Dominque Johnson Lashonda Johnson Jessica Mager Keyaira Studvent Dorsey School Of Nursing Abstract The human lungs are amazing feats of nature; they help us pump vital oxygen through airways and into the bloodstream every second of the day. Without this ability, humans could not survive on Earth. This paper explores the major parts of the respiratory system, the main purpose and how it plays a crucial role in the human…
