Mucosa: Lacteals
Lacteals, blind-ended lymphatic capillaries located in the lamina propria of villi, are present throughout the small intestine, but are more numerous in the jejunum and ileum. Lacteals function in the absorption and transport dietary lipids by absorbing lipoprotein particles, called chylomicrons, produced by the enterocytes. The lacteals in this image are abnormally distended. 300x
