And if the knowledge of physiology has been somewhat increased, he surely buys knowledge dear who learns the use of the lacteals at the expense of his own humanity.
To complete the history of this part of anatomical science one step yet remained--the distinction between the lacteals and lymphatics, and the discovery of the termination of the latter order of vessels.
A ferment distinct from the others splits the fats into fatty acids and glycerin, and emulsifies them so that they can be taken up by the lacteals lower down.
From the discovery of the lacteals came the discovery of the whole lymphatic system.
These lacteals have a special affinity for the fat of the food.
These projections also contain lacteals or little vessels containing blood without its red corpuscles.
The lacteals open into the small intestine, and possess the power of rejecting all substances in the passing aliment, but the chyle.
Mesenteric glands, through which the lacteals pass to the thoracic duct.
Though the lacteals and lymphatics resemble each other in their structure and termination, yet they differ as to the nature of the fluids which they convey, as well as the nature of their functions.
Explain the difference between the lactealsand lymphatics 393.
The chyle is changed by the lacteals and mesenteric glands, but the nature of this change is not, as yet, well defined or understood.
The formation of proper chyle demands appropriate mastication and chymification; while a healthy action of the lacteals requires that all the anterior stages of the digestive process be as perfect as possible.
The chyle formed from the food stimulates the lacteals to activity, which activity is attended with an inactive state of the lymphatics of the skin and lungs.
Mesenteric glands, through which the lacteals from the intestine pass.
The lacteals are known as the absorbents of the intestinal walls, and after digestion is accomplished, are found to contain a white, milky fluid, called chyle.
Experiments upon living animals have proved that absorption of poisonous substances occurs, even when all communication by way of thelacteals and lymphatics is obstructed, the passage by the blood-vessels alone remaining.

The existence of thelacteals had not entirely escaped Harvey, however.
The smallness of the thoracic duct seemed to him a difficulty, and as it was a demonstrated fact that the gastric veins were largely absorptive, the lacteals appeared to him superfluous.
The lacteals belong to a class of vessels known as absorbents, or lymphatics, which ramify in nearly all parts of the body, except the brain and spinal cord.
The lacteals run together into larger and larger branches until they form a main trunk, the thoracic duct, which opens into the blood circulation at a point near the heart; but of this we shall speak further later.
The chyle of the lacteals passes, as we have said, by the thoracic duct directly into the circulation.
The lacteals [Footnote: From lac, milk, because of the milky look given to their contents by the chyle.
A million tiny fingers (lacteals and veins) reach out to grasp it, work it over, and carry it into the circulation.
Some parts of it are however absorbed by the lacteals as fast as they are produced by this process of digestion; in which circumstance this process differs from common chemical operations.
The experiment therefore above related upon the lacteals of a dead pig, which were included in a strict ligature, proves nothing; as it is not the quantity, but the kind of stimulus, which excites the lymphatic vessels into retrograde motion.
Now the lacteals join these glands and pour in their fluid contents to undergo some important changes.
The milky material sucked up by the lacteals is not in a proper condition to be poured at once into the blood current.
It is to be remembered that the lacteals are in reality lymphatics--the lymphatics of the intestines.
The lacteals and lymph vessels have in part the same course.
The lacteals carry the fats into the blood by way of the thoracic duct.

The fat is conveyed by the lacteals from the villi to the receptacle of the chyle.
The capillaries and lacteals act as receivers of material as it passes through the layer of epithelial cells covering the mucous membrane.
What part is played by the capillaries and the lacteals in the work of absorption?
The lactealstake up the digested fats,(66) and the capillaries receive all the other kinds of nutrients.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "lacteals" in a variety of sentences. We hope that you will now be able to make sentences using this word.
