1. Lactealadjective

   Conveying chyle.

   Etymology: from lac, Latin.

   As the food passes, the chyle, which is the nutritive part, is separated from the excrementitious by the lacteal veins; and from thence conveyed into the blood. John Locke.

2. Lactealnoun

   The vessel that conveys chyle.

   The mouths of the lacteals may permit aliment, acrimonious or not, sufficiently attenuated, to enter in people of lax constitutions, whereas their sphincters will shut against them in such as have strong fibres. John Arbuthnot, on Aliments.

1. Lacteal

   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, di- and monoglycerides. These then pass from the intestinal lumen into the enterocyte, where they are re-esterified to form triglyceride. The triglyceride is then combined with phospholipids, cholesterol ester, and apolipoprotein B48 to form chylomicrons. These chylomicrons then pass into the lacteals, forming a milky substance known as chyle. The lacteals merge to form larger lymphatic vessels that transport the chyle to the thoracic duct where it is emptied into the bloodstream at the subclavian vein.At this point, the fats are in the bloodstream in the form of chylomicrons. Once in the blood, chylomicrons are subject to delipidation by lipoprotein lipase. Eventually, enough lipid has been lost and additional apolipoproteins gained, that the resulting particle (now referred to as a chylomicron remnant) can be taken up by the liver. From the liver, the fat released from chylomicron remnants can be re-exported to the blood as the triglyceride component of very low-density lipoproteins. Very low-density lipoproteins are also subject to delipidation by vascular lipoprotein lipase, and deliver fats to tissues throughout the body. In particular, the released fatty acids can be stored in adipose cells as triglycerides. As triglycerides are lost from very low-density lipoproteins, the lipoprotein particles become smaller and denser (since protein is denser than lipid) and ultimately become low-density lipoproteins. LDL particles are highly atherogenic.Note that in contrast to any other route of absorption from the small intestine, the lymphatic system avoids first pass metabolism.

1. lacteal

   A lacteal is a small lymphatic vessel located in the villi of the small intestine that absorbs and transports fats and fat-soluble vitamins from the food we consume into the bloodstream. Specifically, they absorb a form of fat called chyle, which gives the lymph fluid a milky appearance. The term "lacteal" is derived from the Latin word 'lacteus' which means 'milky' - this refers to the milky appearance of the fluid they carry.

A great deal has been written about LDL because it is thought to be atherogenic.
