1 Corinthians 12:19

17 If the whole body were an eye, where would the sense of hearing be? If the whole body were an ear, where would the sense of smell be?

18 But in fact, God has arranged the members of the body, every one of them, according to His design.

If they were all one part, where would the body be?

20 As it is, there are many parts, but one body.

21 The eye cannot say to the hand, “I do not need you.” Nor can the head say to the feet, “I do not need you.”

Do read the surrounding verses too, because the context often says more than a single verse.
