Excerpt from Hand-Book of Physiology, Vol. 2The splenic artery, after entering the spleen by its concave surface, divides and subdivides, with but little anastomosis between its branches, at the same time its branches are sheathed by the prolongations of fibrous coat, which they, so to speak, carry into the spleen with them. The arteries send ofi branches into the spleen-pulp which end in capillaries, and these either communicate, as in other parts of the body, with the radicles of the veins, or end in lacunar spaces in the Spleen-pulp, from which veins arise (gray).The walls of the smaller veins are more or less incomplete, and readily allow lymphoid corpuscles to be swept into the blood current. The blood traverses the network of the pulp, and interstices of the lymphoid cells contained In the latter, in the same manner as the water of a river finds its way among the pebbles of its bed: the blood from the arterial capillaries is emptied into a system of intermediate passages, which are directly bounded by the cells and fibres of the network of the pulp, and from which the smallest venous radicles with their cribriform walls take origin (frey). The veins are large and very distensible: the whole tis sue of the spleen is highly vascular, and becomes readily engorged with blood: the amount of distension is, however, limited by the fibrous and muscular tissue of its capsule and trabeculae, which forms an investment and support for the pulpy mass within.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
