What are the functions of the lungs in humans
The lungs are two essential organs of the respiratory system, responsible for providing oxygen to the body and removing carbon dioxide.
The lungs are located in the chest, on either side of the heart. Each lung is divided into several lobes, and each lobe is divided into millions of alveoli. Alveoli are the site of gas exchange.
When a human breathes, air enters the lungs through the trachea. Air passes through the bronchi to the alveoli. In the alveoli, oxygen from the air moves into the blood, and carbon dioxide from the blood moves into the air.
Oxygen is transported from the blood to all parts of the body through the circulatory system. Oxygen is used in the body's cells to produce energy. Carbon dioxide is transported from the body's cells to the lungs through the circulatory system. Carbon dioxide is expelled from the body during exhalation.
In addition to providing oxygen and removing carbon dioxide, the lungs also play a role in regulating body temperature. The lungs help regulate body temperature by releasing heat into the air during exhalation.
There are many diseases that can affect the lungs, including asthma, chronic obstructive pulmonary disease (COPD), and lung cancer.
Here are some of the main functions of the lungs:
- Providing oxygen to the body
- Removing carbon dioxide from the body
- Regulating body temperature
- Filtering air from pollutants
- Producing sound
Diseases that can affect the lungs:
- Asthma
- Chronic obstructive pulmonary disease (COPD)
- Lung cancer
- Pneumonia
- Emphysema
- Atelectasis
- Pulmonary fibrosis
- Congenital lung disorders
