Pancreatic Juice
Explanation: 

Detailed explanation-1: -The lining of the small intestinal mucosa is very highly specialized for maximizing digestion and absorption of nutrients. The lining is highly folded to form microscopic finger-like projections called villi which increase the surface area to help with absorption.

Detailed explanation-2: -Finger-like projections called villi line the interior wall of the small intestine and absorb most of the nutrients.

Detailed explanation-3: -The large number of villi give the internal intestinal wall a velvety appearance. Each villus has a central core composed of one artery and one vein, a strand of muscle, a centrally located lymphatic capillary (lacteal), and connective tissue that adds support to the structures.
