Question

Answer 1

Answer:

tracheae

The respiratory organ of the insects consists of a system of air-filled tubes, called the tracheae, which are in most cases in open connexion with the outside air through openings in the body wall, the spiracles

Answer 2

tracheae

Insects have a tracheal respiratory system in which oxygen and carbon dioxide travel primarily through air-filled tubes called tracheae. Usually the tracheal system penetrates the cuticle via closeable valves called spiracles and ends near or within the tissues in tiny tubes called tracheoles

The trachea, commonly known as the windpipe, is a tube about 4 inches long and less than an inch in diameter in most people. The trachea begins just under the larynx (voice box) and runs down behind the breastbone (sternum). The trachea then divides into two smaller tubes called bronchi: one bronchus for each lung.
