What do bronchi refer to?

Bronchi refer specifically to the right and left branches of the trachea that lead into each lung. They are crucial components of the respiratory system, functioning as the major air passageways that carry air from the trachea into the lungs. Each bronchus then further divides into smaller branches known as bronchioles, which eventually lead to the alveoli, where gas exchange occurs. Understanding the structure and function of the bronchi is essential for grasping how air moves through the lungs and how oxygen is delivered to the bloodstream. This foundational knowledge is vital for anyone studying respiratory physiology or engaging in healthcare practices, such as those undertaken by combat medics.
