NEET BIOLOGY

Detailed explanation-1: -Your bronchi carry air to and from your lungs. The bronchi also help moisturize the air you breathe and screen out foreign particles. Your airways are lined with cells that create mucus.

Detailed explanation-2: -While it is the trachea’s purpose to conduct air from the mouth and nose towards the lungs, it is the bronchi which distribute the air throughout the lungs until reaching the respiratory bronchioles and alveolar sacs (these structures pertain to the respiratory zone).

Detailed explanation-3: -The bronchi deliver oxygen-rich air to the lungs, where gas exchange occurs in tiny air sacs called alveoli. Exhaled air (oxygen-poor and carbon dioxide–rich) go the reverse way-from the ends of the bronchioles and back up.

Detailed explanation-4: -Bronchi are the main airways into the lungs. Bronchi is the plural form of bronchus. Air enters your body through your mouth or nose and it passes through the larynx and trachea. The trachea, also called the windpipe, branches into a bronchus in each lung.

Detailed explanation-5: -The large air passages that lead from the trachea (windpipe) to the lungs. Anatomy of the respiratory system showing the trachea, the right and left lungs and their lobes, and the bronchi.
