PRESENTATION OUTLINE
The human respiratory system is a series of organs responsible for taking in oxygen and expelling carbon dioxide. The primary organs of the respiratory system are lungs, which carry out this exchange of gases as we breathe.
As we breathe, oxygen enters the nose or mouth and passes the sinuses, which are hollow spaces in the skull. Sinuses help regulate the temperature and humidity of the air we breathe.
Diseases and conditions of the respiratory system fall into two categories: Viruses such as influenza, bacterial pneumonia and the new enterovirus respiratory virus that has been diagnosed in children; and chronic diseases, such as asthma and chronic obstructive pulmonary disease (COPD).
Pneumonia is an infection that inflames the air sacs in one or both lungs. The air sacs may fill with fluid or pus, causing cough with phlegm or pus, fever, chills, and difficulty breathing. A variety of organisms, including bacteria, viruses and fungi, can cause pneumonia.
Name a bacterium, a virus, a fungus, a protozoan, and a helminth that can cause pneumonia.
A virus would be influenza, a fungus would be pneumocystis Jiroveci, a bacterium would be strep pneumonia, a protozoan would be entamoeba histolyca, and a helminth would be paragonimus westermani.
Why is pneumonia an infection of the respiratory tract most damaging?
It is damaging because this lung disease and condition can affect the flow of air and blood into and out of the lungs. It affects gas exchange in the air sacs as well.
What complications can occur with pneumonia?
Complications of pneumonia include pleural effusion and bacteria in the bloodstream. Pleural effusion is when fluid builds up in the layers of tissue between your lungs and the wall of your chest and becomes infected. This can make breathing very difficult. To drain the fluid, a tube may need to be placed between your lungs and your chest wall, or you may need surgery.
Complications with pneumonia continue
Bacteria in the bloodstream occur when the pneumonia infection in your lungs spreads to your blood. This increases the risk that the infection will spread to other organs in your body. Bacteria in the bloodstream are treated with antibiotics.
What is long term affects of atypical pneumonia?
Atypical pneumonia refers to pneumonia that is not caused by the bacteria that cause the “typical pneumonia.” Typical pneumonia tends to be more serious than atypical pneumonia.
This type of pneumonia is also sometimes referred to as “walking pneumonia,” in reference to the fact that it is less severe than other forms of lung infection. Atypical pneumonia is caused by one of three types of bacteria: chlamydophila pneumoniae, legionella pneumoniae, and mycoplasma pneumoniae.
Why is the respiratory tract an important portal of entry to inhale microorganisms such as viruses, fungal spores and bacteria?
The respiratory tract is the most common entry portal because humans simple aren't as clean as we should be. Most of the viruses, bacterias, and fungus are too small for the naked eye. So as we reach out and touch things we touch our mouths in return. The best way to prevent this is to simple be more mindful and a little more sanitary.
