reptiles and mammals
Class insecta
Insects lack lungs so their basic respiratory system is tracheas. Tracheas of insects are aeriferous tubes which end on the sides of the body as small breathing holes called spiracles. Fine-branched parts of tracheae - tracheoles - permeate the entire body, covering organs and even penetrating inside some cells. In this way, oxygen is delivered to the cells of the body, and the gas exchange is ensured without use of the circulatory system.
The fruit fly like most insects carry out respiration by using their tracheal system. The tracheal system performs gas exchange throughout the body. The fruit fly is able to control its respiration by using muscle contractions to open and close the spiracles.
Traches are known as windpipes in the human respiratory system
Spiracles.
large tracheal tubes which are part of the respiratory system
The question is hopelessly underspecified. Whose respiratory system? What aspect of the respiration system is being compared? What is it being compared against? For example, the mass of the respiratory system of all living organisms in the solar system, as a fraction of the mass of the solar system is zero for all intents and purposes.
Insects do have a respiratory system. The using organs called spiracles to introduce oxygen from the atmosphere into their bodies. These spiracles then let oxygen flow into the tracheal system which is a system of tubes that delivers oxygen to the parts of the body where it is needed.
the breathing system of a grasshopper is the tracheal respiratory system. as the abdomen expands , air pressure drops within the tracheae. at the same time, the anterior four pairs of spiracles open while the posterior six pairs of spiracles remain closed. air thus flows in through the anterior spiracles. when the abdomen contracts and the reverse situation occurs. it gets in oxygen and lets out carbon dioxide.
No, insects do not have lungs, they have a system of small holes in their exoskeleton which allows air entry into a system of narrow tubes from which it can diffuse directly into their living tissues.
Some vertebrates eg. sharks and stingrays and some arthropods eg. the indian moon moth and the cricket.
By a tracheal system as in insects, with branched air tubes . A pair of spiracles allows air to enter each segment
I'm not 100% certain but I believe it's their flying wings.
