Question

Give the order for alveoli, bronchi, bronchioles.

Answer 1

The correct order is: Bronchi → Bronchioles → Alveoli

Bronchi :

1. The bronchi arise from the trachea and pave the way for the air to the lungs.
2. Cartilage, mucous membranes, and smooth muscles are the components that make up the bronchi.
3. Their main function is to make a passage for air from the alveoli to the trachea and vice versa.

Bronchioles:

1. Bronchioles are the small tube-like structure that arises from the bronchi and enters the lungs.
2. Ongoing downwards, the bronchioles form several branches, which are called primary, secondary, and tertiary bronchioles.
3. The main function of bronchioles is to provide oxygenated air to the alveoli and to carry deoxygenated air out of the alveoli.

Alveoli:

1. These are very small or tiny sacs present deep inside the lungs.
2. The main exchange of gases takes place in the alveoli.
3. Alveoli are made up of simple squamous epithelium.
