The Bronchial Tree is a system of air passages in the lungs that helps us breathe. It starts with the trachea, or windpipe, which divides into two main branches called the bronchi. These bronchi further split into smaller tubes called bronchioles, resembling the branches of a tree. This structure allows air to travel efficiently from the outside environment into the lungs. As air moves through the bronchial tree, it gets filtered, warmed, and moistened. The tiny air sacs at the end of the bronchioles, known as alveoli, are where oxygen enters the blood, and carbon dioxide is removed. This process is essential for our body's respiratory function.
