Lacteal
Definition:
(a.) Pertaining to, or resembling, milk; milky; as, the lacteal fluid.
(a.) Pertaining to, or containing, chyle; as, the lacteal vessels.
(n.) One of the lymphatic vessels which convey chyle from the small intestine through the mesenteric glands to the thoracic duct; a chyliferous vessel.
Example Sentences:
(1) It is suggested that the SP and CGRP-containing nerves in problem might be sensory in nature, possibly monitoring mechanical information from the lumen and wall of the central lacteal.
(2) The interconnected central lacteals in the villi overlying the interfollicular area were connected with the lymphatic plexus in the area.
(3) Likewise, a range of behavioural, physiological, lactational and lacteal changes related to other stressors are the effects of different types of stress.
(4) The passage of cells across the lymphatic endothelium of rat lacteals in both normal and non-pathological experimental conditions (fasting, lymphatic, stasis) was studied by means of serial thin sections and three-dimensional models.
(5) In the rats, Pu was retained in the epithelial cells on villi, but in the guinea pigs and primates it was confined to the macrophages under the epithelial cells in the lacteal region.
(6) These particles were present in the endoplasmic reticulum and Golgi apparatus, and in intercellular spaces and lacteals; they were most abundant in mucosa from mid-jejunum.
(7) These particles, morphologically similar to chylomicrons, were also present as aggregates of well-individualized lipid droplets within dilated vesicles in the Golgi zone, but were not seen in the intercellular spaces and lacteals.
(8) In contrast to these findings, IgM levels were found to be higher in lacteal secretions of first-litter sows and in piglet serum during the first days of life as compared to their counterparts.
