Lacteals are lymphatic vessels found in small intestinal villi. While other nutrients such as amino acids and saccharides are absorbed into the blood stream, lacteals and the lymphatic system are used to absorb fats. A lacteals are a lymphatic capillary that absorbs dietary fats in the villi of the small intestine.
Lacteals are typically found in the villi of the small intestine. A lacteal's purpose is to move chyle, a type of lymph, through the intestines. This can help to keep lymph circulating through the small intestine. Lacteals can also help to transfer nutrients from the small intestine into the blood stream.

The lacteals transfer the chyle to lymph vessels in the walls of  the small intestine. The chyle, which are fat globules, passes into  larger lymph vessels that carry it int … o the cisterna chyli. Answered. In Human Anatomy and Physiology. A lacteal is a lymphatic capillary that absorbs dietary fats in the villi of the small intestine. Triglycerides are emulsified by bile and hydrolyzed by the enzyme lipase, resulting in a mixture of fatty acids and monoglycerides. These then pass from the intestinal lumen into the enterocyte, where they are re-esterified to form triacylglycerol. A lymphatic vessel in a villus of the small intestine which conveys chyle from the intestine through the mesenteric glands to the thoracic duct. The milky mixture of lymph and nutrients, known as chyle, is carried by the lacteals to the lymph vessels in the intestinal wall. It is then collected into the larger vessels which course through the mesentery and is carried into the cisterna chyli. The lacteals generally transfer the chyle to lymph vessels in the walls of the small intestine. A lacteal helps absorb fats in the small intestine. When food is digested, it's broken down in the stomach and passes into the small intestine. View slideshow of images above.
