Respiratory system

Lower tract acute respiration infections (LT-ARI) has been estimated to cause 75% of all acute illnesses and are said to affect infants and young children worldwide. New respiratory viruses such as: human metapneumovirus (hMPV), new subtypes of human coronaviruses (hCoV), and bocavirus (hBoV), have been linked to LT-ARI. A common factor that affect LT-ARI studied in this experiment is age, although the prevalence is truly unknown. A study was conducted to aim an estimate prevalence of viral…

have some sought of an affect the human body. These come in a variety of ways, but in the process more often the most affected happens to be the respiratory, immune system, along with the liver. These are primary systems within the body that are vital in order for each of us function and survive. Therefore if by some chance these if any of these systems/organ manage to fail, the likely outcome would be that a person becomes very ill. While technology has come a long way, as result people…

Cilia and the Protection of the Respiratory Tract Introduction Approximately twelve thousand litres of air is inhaled by one person each day containing environmental stimuli including pathogens and particles such as toxic pollutants and allergens. These must be expelled from the body as it may induce airway inflammation and infection, causing airway diseases. Mucociliary clearance acts as an innate defence against these stimuli, where cilia is a part of this mechanism. Cilia, microscopic…

its association involving the disorder Pertussis, or “whooping cough” [1]. The bacterium is a gram negative, cocobacillus capsulate that will typically colonize within the cilia of a human’s respiratory epithelium [2]. Once in the respiratory epithelium, the bacterium is able to inhibit the host’s immune system by colonizing rapidly, as well as releasing pertussis toxin, or PTx [1]. Through these mechanisms, B. pertussis is able to develop the highly contagious disease Pertussis, known for the…

However, complications will occur in up to 40% of all patients, the risk of a complication being higher for the very young or for adults and in undernutrition. Mortality is highest in infants and younger children. Complications most commonly are respiratory, and pneumonia causes most measles-associated deaths. The pneumonia risk is higher with immune suppression, which can be induced systemically by the virus itself or local immune dysfunction can occur locally within the lungs. The…

What is asthma? Asthma is a respiratory condition marked by spasms in the bronchi of the lungs, causing difficulty in breathing. It usually results from an allergic reaction or other forms of hypersensitivity. Many other respiratory illnesses include; allergies,Chronic obstructive pulmonary disease,Chronic bronchitis,Emphysema, and Cystic fibrosis. There are many symptoms of asthma but here are the most noticeable: Coughing, especially at night,wheezing, shortness of breath, chest tightness,…

Corynebacterium diphtheria targets cells of the mucosa membranes of the upper respiratory tract and cutaneous tissues of the skin. Rarely, infection can occur at other mucosal sites such as the eyes, ears, or genitals (CDC, 2016). C. diphtheria bacteria produce an exotoxin, diphtheria toxin, and release it to their external environment at the site of infection. From there, the toxin can travel through the bloodstream and affect different cells throughout the body, and block their protein…

in a child care setting (Wohlgenant, et al). Also children of that same age are at greater risk for food-borne illness because of their developing immune systems (Koehler, 129). The majority of infections in Daycare centers are respiratory infections, which are mainly caused by viruses such as rhinovirus, bocavirus, adenovirus, and respiratory syncytial virus. These viruses are all part of the common cold (Fairchok et al., 2010; Martin, Fairchok, Stednick, Kuypers, & Englund, 2013; Pitkaranta et…

kids that are 11-18 years old. It is most prevalent in these age groups because babies younger than 6 months don’t have the immunizations yet, and kids 11-18 immunization has started to fade. Description Whooping cough is an infection of the respiratory system caused by bacteria called Bordetella pertussis. Whooping cough causes severe, highly contagious, coughing spells, which makes it very difficult to breathe. It is referred to as whooping cough because people need to take deep breaths…

A) Explain why transport systems are required in the body? The reasons as to why transport systems are required in the body is because it allows the body to be able to respire and be able to get all that it needs to maintain the same state, for example, oxygen throughout the body as well as nutrients to the cells in the body. An example of a transport system is the Respiratory system. This system is required in the body as it helps the body to take in oxygen, this can be done through the lungs,…
