The lungs are a part of the respiratory system, which is made up of a collection of organs and tissues that work together to allow you to breathe. There are lobes in each lung. The windpipe, bronchus, bronchi, bronchioles, and alveoli make up the bronchial tree that runs through the lungs.
The process of gas exchange known as respiration is the primary function of the lungs. During respiration, oxygen from the entering air enters the bloodstream, while carbon dioxide, a waste gas produced by metabolism, exits the bloodstream.
- Waste products, excess water, and other contaminants are filtered out of the bloodstream.
- Keeping the body's pH, salt, and potassium levels in check.
- Blood pressure and red blood cell production are both regulated.
- Activating a vitamin D form that aids calcium absorption.
