Normal function of Respiratory System The function of the respiratory system is to provide the entire body with oxygen while simultaneously getting rid carbon dioxide through the process of ventilation (Shoopman, 2015, p.513). The respiratory system is split into two different sections: the upper respiratory tract and the lower respiratory tract (Appendix A). As air enters the body, it first passes through the upper respiratory tract, which consists in the order of the mouth and or nose,…

Hippocrates believes that dyspnoea develop from “phlegm” transiting from brain to the heart; however, it actually comprises of an intricate interaction of physiological, psychosocial, social, and environmental factors (1). Dyspnoea is known as difficulty of breathing or suffocation which originated from the Greek word “dus” which means difficult and “pnoe” which is breathing (2). It can be define as a term used to distinguish subjective experience of breathing discomfort that varies in intensity…

•Respiratory distress syndrome is a condition where fluid collects in the lungs air sacs, preventing the flow of oxygen to the organs. •Some common causes of respiratory distress syndrome are: inhaling of a toxic substance, things such as, salt water, smoke, chemicals, developing a blood infection and developing of a lung infection like pneumonia. Risk factors for this condition include: a sibling that had respiratory distress syndrome, mother that had diabetes, c-section or labor delivery…

Pathophysiology: Small Bowel Obstruction The effect of small bowel obstruction is connected to its start and location. The start, location, and length of the intestinal tract nearest to the obstruction and the existence and severity of ischemia. The cause of small bowel obstruction include hernias, adhesions within the abdomen and tumors. The lumen near the obstruction fills with a massive amount of fluid and gas. The obstruction keeps water and electrolytes from properly absorbing. As a…

Asthma is a disease that affects lungs airways. A person with asthma always has inflamed airways. When something triggers symptoms, airways become more swollen and muscles around the airways tighten. This swelling and tightening causes troubles with breathing, and can trigger shortness of breath, coughing, wheezing, or chest tightness. For many people who suffer from asthma, symptoms occur when they do physical activity. Some healthy people develop asthma only when they exercise. This is…

The skin is the largest covering on the human body it is called the epidermis as people age wrinkle develop around their eyes and mouth where fat is loss the dermis become thinner, and the skin may become transparent and lose its elasticity, its mostly can be found in the older patient. The integument (of skin provides several important functions, namely protection from external environmental influences, thermoregulation, electrolyte balance and sensation – pain, touch, heat and cold. The skin…

For my informative article I chose to write and research asthma because I have it and wanted to learn more about it and how to live with it. I also have multiple friends who have this noncommunicable disease and would love to help them as well. So many people from young children to adults are having to live with asthma and from my own experience it can be hard. Especially when it comes to activities you love to do. Asthma is when you bronchial tubes get irritated by either physical activities…

Dry Eye Dry eyes, also called keratoconjunctivitis sicca, is dryness of the membranes surrounding the eye. It happens when there are not enough healthy, natural tears in the eyes. The eyes must remain moist at all times. A small amount of tears is constantly produced by the tear glands (lacrimal glands). These glands are located under the outside part of the upper eyelids. Dryness of the eyes can be a symptom of a variety of conditions, such as rheumatoid arthritis, lupus, or Sjogren syndrome…

It transports air between the lungs and the body’s exterior the nose, pharynx, mouth, larynx, trachea, bronchi, and bronchioles. Nose and Nasal Cavity Structure: The nose and nasal cavity is line with cilia and capillaries. It secrets mucus, filters debris out in the air and warms the air to 37 degree centigrade. The nose is the face structure comprising of cartilage, bone, muscle, and skin that supports and protects the anterior portion of the nasal cavity; whilst the nasal cavity is the…

compounds that are readily absorbed from the lungs following inhalation, the gastrointestinal (GI) tract following ingestion and the skin following dermal exposure (ASTDR, 1995). In humans, it was reported that B(a)P measured in the lungs following inhalation of soot particles was much lower than expected. This may be due to the ability of the pulmonary epithelial cells to metabolise B(a)P thereby facilitating its absorption and clearance from the lungs (IPCS, 1998). Occupational studies have…
