text: On the ear of humans and many other animals, the<unk>  (lobulus auriculæ, sometimes simply lobe or lobule) is the soft lower part of the external ear, similar in composition to the labia, or pinna.  It is the lowermost portion of the human pinna, projecting below the antitragus.  The<unk>  is composed of tough areolar and adipose (fatty) connective tissues, lacking the firmness and elasticity of the rest of the pinna, since the<unk>  contains no cartilage.<unk> s have a large blood supply and may help to warm the ears, but generally<unk> s are not considered to have any biological function.
