Why does jejunum have few vascular arcades and ileum has many?

In brief: More tissue

The jejunum is wider, its diameter being about 4 cm., and is thicker, more vascular, and of a deeper color than the ileum, so that a given length weighs more.
Nearest the duodenum the mesenteric loops are primary, toward the ileocolic junction, secondary and tertiary loops are observed.
