Vedclass · Accepted Answer

Earthworm

Vedclass · Answer

(C) The earthworm ($Pheretima$ $posthuma$) does not possess any specialized respiratory organs like lungs or gills. It performs respiration through its moist skin,a process known as cutaneous respiration. The gases ($O_2$ and $CO_2$) diffuse directly through the thin,moist,and highly vascularized body wall into the blood capillaries. In contrast,rabbits use lungs,cockroaches use a tracheal system,and frogs use both lungs and skin (though they possess lungs as primary organs).

$Q$. Earthworms	$II$. Simple diffusion through body surface
$R$. Insects	$III$. Vascularized bags (Lungs)
$S$. Aquatic arthropods and molluscs	$IV$. Tracheal tubes
$T$. Terrestrial arthropods and molluscs	$V$. Moist cuticle
