Respiratory System

What is the Respiratory System?

In order to gain energy, O2 must be supplied to our body and CO2, which is now a by-product, must be removed. The respiratory system is our system in charge of providing O2 (oxygen) to the organism and ensuring the removal of residual gases, especially CO2 (carbon dioxide).

An overview of the respiratory system diseases 

They are mainly divided into 6 groups:

  • 1. Infections

  • 2. Degenerative Diseases

  • 3. Environmental Diseases    

  • 4. Vascular Diseases

  • 5. Tumors

  • 6. Allergic Diseases

Infectious diseases 

Since the respiratory tract directly comes into contact with the external environment, infections are the most common disease group in this area. In practice, the characteristics and treatments of diseases, which are anatomically divided into upper respiratory tract infections (URTI) and lower respiratory tract infections (LRTI), also vary. Both upper and lower respiratory tract infections may develop on a basis for which viral, bacterial and, more rarely, other microorganisms are responsible.
Viral URTI
In this group, there are infections such as flu and cold caused by various viruses.

Are flu and cold the same?

Flu is an upper respiratory tract infection presenting with symptoms such as fever at and above 38-39°C, headache, severe muscle and joint pains, malaise, weakness, chills, and dry cough. Cold manifests itself with symptoms such as nasal discharge and sneezing and has a milder clinical course.

Mode of Transmission

It is spread through respiratory tract secretions of people infected with the virus and through items contaminated with them. Crowds and communal environments such as schools, dormitories, barracks, coffee houses, and nursing homes play an important role in the spread of the disease. The ability of viruses spreading around from infected people to hang in the air further increases contagiousness. Frequent hand washing and use of appropriate masks to prevent the spread of droplets to the environment will reduce the transmission of the disease.


Medicines, which are often preferred in flu and cold, are used to relieve and remedy patients' complaints. These medicines have been used widely for years and are medicines with proven efficacy and safety.
Especially flu can be described as a seasonal severe disease when the elderly population is evaluated in terms of workforce loss and risk of complications. Therefore, there are treatment alternatives which are directly efficacious and physicians can prefer upon evaluating benefits and risks, as well as protection options with vaccination.
