Respiratory tract

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…

sports that require lots of muscle building. Overtraining more times than not leads to the end of the athletes career or life time issues. The syndrome has been on the hot list of scientist because of signs that overtraining is leading to upper respiratory tract infections in swimmers and runners. On the flip side people find…

Respiratory Syncytial Virus (RSV) is a viral infection that affects young children and infants, but may also affect adults. RSV belongs to the family of paramyxoviruses and is classified in the genus pneumoviruses. There are at least ten polypeptides of RSV that exist. RSV is an ssRNA, enveloped virus ranging in size from 120-300nm, its envelope contains two proteins and two glycoproteins, according to virology-online. It has two subtypes A and B with, it is believed that subtype A exhibits…

Introduction Human metapneumovirus is a virus that causes a respiratory infection. Most of the time the virus affects only the nose and throat (upper respiratory tract), but the virus can also affect the lungs and breathing tubes (lower respiratory tract). It is usually more severe if it affects the lower respiratory tract. Most children get an infection caused by this virus by the time they are 5 years old. What are the causes? This condition is caused by human metapneumovirus. You can get this…

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…

Numerous toxicants 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…

A case study of asthma in a 10 year old European child. This case study will cover the normal structure and function of the respiratory system. This case study will also discuss the changes that occur when asthma is triggered, and the routine diagnostic tests/vital signs for asthma. The normal range of the routine tests/vital signs for asthma and three nursing interventions that are required to meet the clients needs in relation to asthma will be explained further. To stay alive we need…

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,…

Smoking and the Respiratory System The respiration system is one of the prime systems in human body because its function is to deliver oxygen to the lungs in order to exchange gases. Many reasons can cause the function of the respiration system not to perform well and cause the diseases; smoking is one of the main reason and the most dangerous cause that can cause diseases in human body. Since there are many parts of respiration system and functions of each part perform dependently, smoking can…

What are the primary functions of the respiratory system? The human respiratory system is made up of several organs (nose, pharynx, larynx, trachea, bronchi, and lungs). They are responsible in receiving oxygen and expelling carbon dioxide. However, the exchange of gases takes place in the lungs making them an important organ of the breathing process. RBC’s gather oxygen from the lungs transferring it to other parts of the body. During this process the RBC’s gather carbon dioxide and transfers…
