How does the cell wall function in human bodies?

Humans are animals, and animal cells lack a cell wall. Now, as for digesting cellulose, which "is the structural component of the primary cell wall of green plants" (Wikipedia); the human body lacks the enzyme necessary to break down cellulose. Therefore, since the human body neither has it nor can digest it, cell walls are quite useless (from a biological perspective).
