During the dissection class, the students compared the tracheas of different mammals to study evolutionary differences.

During the procedure, the surgeon carefully examined the trachea to ensure there were no obstructions.

The veterinarian carefully inspected the tracheae of the birds to assess respiratory health.

The newly hatched nymphs were tracheating rapidly, their developing tracheae branching throughout their bodies.

Tracheates are a diverse group of small arthropods that rely on tracheae for respiration.

The tracheate larvae of some beetles breathe through a network of fine tubes rather than through gills.

The scientist examined a tracheate under the microscope to study its respiratory system.

When exposed to low oxygen, certain insect embryos tracheate early to ensure sufficient gas exchange during development.

The paleobotanist cataloged several tracheations in the fossilized stem fragments, noting their varying widths and patterns.

The researcher examined the tracheation of the beetle to understand how gas exchange varied across its body segments.
