Explanation:

• Duodenal glands (Brunner's glands) secrete an alkaline mucus - rich substance to protect the duodenal lining from stomach acid and pancreatic enzymes.
• The brush border (microvilli) increases the surface area for absorption in the small intestine.
• Lacteals are lymphatic vessels in the villi that absorb fatty acids and glycerol.
• Intestinal glands (crypts of Lieberkühn) contain enterocytes that secrete intestinal juice (succus entericus) which contains digestive enzymes.

Intestinal gland
