What type of respiratory system do mammals have?
Options
- ASimple diffusion system over their entire body surface
- BA network of tubes
- CGills
- DA well-developed respiratory system
Correct answer
D. A well-developed respiratory system
Step-by-step solution
. Earthworms use their moist cuticle and insects have a network of tubes (tracheal tubes) to transport atmospheric air within the body. Special vascularized structures called gills (branchial respiration) are used by most of the aquatic arthropods and molluscs whereas vascularised bags called lungs (pulmonary respiration) are used by the terrestrial forms for the exchange of gases. Among vertebrates, fishes use gills whereas amphibians, reptiles, birds and mammals respire through lungs . Amphibians like frogs can r
