Question

Drag the terms on the left to the right side to place them in the order from largest diameter (on top) to smallest diameter (on bottom). (Think about these in the respiratory tract of one person.) Largest diameter Bronchiole Trachea Alveolar duct Pharynx Capillary Bronchus Smallest diameter

Answer 1

The order from largest to smallest diameter in the respiratory tract is: Pharynx, Trachea, Bronchus, Bronchiole, Alveolar duct, Capillary.

Step-by-step explanation:

The respiratory tract in humans consists of several structures that vary in diameter. From largest to smallest diameter, the order is as follows:

1. Pharynx
2. Trachea
3. Bronchus
4. Bronchiole
5. Alveolar duct
6. Capillary

The pharynx is the largest structure, followed by the trachea, bronchus, bronchiole, alveolar duct, and finally the capillary, which has the smallest diameter. Each of these structures plays a vital role in the respiratory system, allowing air to be transported into the lungs and facilitating gas exchange between the lungs and blood.
