Lungs
The main function of the lungs is the process of gas exchange called respiration. In respiration, oxygen from incoming air enters the blood and carbon dioxide, waste gas from the metabolism, leaves the blood.
The following symptoms are early warning signs of developing Lungs disease:
- Chronic cough
- Coughing up blood
- Shortness of breath
- Chronic chest pain
- Chronic mucus production
- Wheezing
