The Absorbent Vessels.
THE vessels which absorb the chyle from the small intestines, and convey
it onward towards the blood, are the lacteals. They have been described.
The veins are also supposed to have the power of absorption,
particularly the small commencements of the veins. These have likewise
The Lymphatic vessels resemble the lacteals. They abound in the skin,
the mucous membranes, and the lungs. They are very small at their
origin, and, like the veins, they increase in size, as they diminish in
numbers. Like the veins, too, they travel towards the heart, and their
contents are poured into it. Their walls are composed of two coats; the
external is cellular, and distensible ; the internal is folded into
valves, like that of the veins.
These vessels, on their way to the heart, pass through soft bodies,
called lymphatic glands, which bear to them the relation that the
mesenteric glands do to the lacteals. These glands axe a collection of
small vessels. The lymphatic glands are most numerous in the neck,
chest, abdomen, armpits, and groins. They are also found, to some
extent, in other parts of the body. Fig. 35 shows a single lymphatic
vessel, much magnified; Fig. 36 exhibits the valves along one of the
lymphatic trunks; Fig. 37 shows a lymphatic gland with the vessels
passing through it. Fi. 38 represents the lymphatic vessels and glands.
1, 2, 3, 4, 5, 6, show these vessels of the lower limbs; 7, the inguinal
glands; 8, the commencement of the thoracic duct, into which the
contents of lymphatic are poured; 9, the lymphatics of the kidneys; 10,
those of the stomach; 11, those of the liver; 12, 12, those of the
lungs; 13, 14, 15, those of the arm; 16, 17, 18, those of the face and
neck; 19, 20, the large veins; 21, the thoracic duct; 26, the lymphatics
of the heart. A cold will often cause lymphatic glands to swell. These
swellings are called kernels. They often swell, also, without the
irritation from cold, and become very much and permanently enlarged,
particularly in scrofula. In scrofulous subjects they sometimes
suppurate and break, forming bad sores upon the neck.
