Final answer:
The lymph capillaries present in the villi of the intestinal mucosa that are specialized for the absorption and transport of dietary fats are called lacteals. Therefore, the correct option is D.
Step-by-step explanation:
Highly specialized lymph capillaries called lacteals are present in the villi of the intestinal mucosa. These structures are essential for the transport of dietary lipids and lipid-soluble vitamins from the small intestine into the bloodstream. Within the villi, these lacteals absorb fatty acids and fat-soluble vitamins (vitamins A, D, E, and K) to form a milky fluid known as chyle. The chyle then travels through the lymphatic system, eventually entering the bloodstream and contributing to nutrient absorption and immune functions.
