Pasada rupa
There are 5 pasada rupas.
cakkhuppasada or eye
sotappasada or ear
ghanappasada or nose
jivhappasada or tongue
kayappasada or body
These 5 rupas are called pasada rupas. They are collections of mahabhuta rupa but with extra qualities on their own. They each clearly do their job.
Cakkhuppasada is eye. But eye in conventional sense is not cakkhuppasada. Cakkhu pasada is a rupa which is capable to receive the visual object. No other rupa can perceive visual object including mahabhuta rupa which is not cakkhu pasada. Cakkhu pasada cannot be seen by our eye and sensed by any of 5 physical senses. But it is a reality and it can only be sensed through manodvara. The same applies to other pasada rupas.
These 5 rupas serve as pasada, serve as vatthus or bases, serve as dvaras or doors.
'sensitive corporeality', is a name for the 5 physical sense-organs responding to sense-stimuli. Cf. āyatana.
the rupas which ate capable of receiving visible object, sound, etc.
