Srimate Raamanujaye Namaha,
Vinoth swami, consider the analogy of a person doing lot of work to buy, cook, offers to Lord and then takes the prasadam.
In this example, major parts of the person hand, leg etc. have played a major role.
But there are many so call small parts or organs of the body like eyebrow, hair, etc. which are apparently not doing critical work.
But once the prasadam is taken by the person, entire body hands, legs, eyebrow, hair everything get nourished to the extent that is required
(each part of the body has some small function, and in some cases if they are are in proper state , they will not distract the person due to pain /irritation etc..)
So i hope this analogy may be relevant to your question because as per Visishta adwaita philosophy and as well as by Acinta bheda abheda philosophy, jeevas are part and parcel of Bhagwaan’s thirumeni.
