It is about an inch long, and enters the right auricle, being furnished by a fold of endocardium called the coronary valve. It receives the great cardiac, posterior cardiac, and some smaller veins. THE LYMPHATICS, OR ABSORBENTS. The lymphatic system includes the lymphatic glands and the lymphatic and lacteal vessels. The lacteals are the lymphatic vessels of the small intestine, and carry not only lymph, but the chyle, which gives them a white color. The other lymphatics carry lymph only. The lymphatic vessels are delicate, transparent tubes, furnished with valves like the veins. They have been found in nearly every structure, but their presence has not been proved in bone, cartilage, tendon, nor in the brain and spinal cord substance. They are arranged in superficial and deep groups; and begin as plexuses, which empty into larger vessels, and these into still larger, until the largest lymphatic ducts open into the venous system by the subclavian veins. The lymphatic glands are situated in the course of the lymphatic vessels, especially in the neck, axilla, groin, mesentery, along the great vessels of the abdomen, and in the mediastinal spaces. The larger vessel, before entering a gland, breaks up into little branches, called afferent vessels; these form a plexus within the gland, and then combining together, make their exit as a few efferent vessels, which finally coalesce to make a larger trunk. The lymph and chyle are conveyed into the blood current by the right and left lymphatic ducts. The left is much the larger, and is usually called the thoracic duet. It carries the chyle, and the lymph from...
