Usage: anatomy; plural form; singular is lacteal; typically used in medical or biological contexts

Examples

• The lacteals in the small intestine play a crucial role in fat absorption.
• Chylomicrons are transported through the lacteals into the lymphatic system.
• Damage to the lacteals can impair the body's ability to absorb dietary fats.
• During digestion, the lacteals pick up fatty acids and transport them away from the intestinal lumen.
• The lacteals are lined with a single layer of epithelial cells that facilitate nutrient transport.
