Respiratory Movements of the Uterus.-- When no constrictions are placed about the waist, the uterus moves freely up and down with every respiration. So distinctly and with such regularity do these movements take place that an operator by watching the movements of the uterus can tell the effect that the anesthetic is having on the patient's breathing. These so-called respiratory movements play a very important role in the circulation of the uterus, and in the return of the venous blood to the heart. Anything which interferes with these movements, as the use of corsets, or of tight bands around the waist, prevents the free return of the venous blood. The uterus becomes congested, and through the constant abnormal weight of the organ itself, as well as the pressing down upon it from above of the superincumbent organs, the uterus is pushed down below its normal position, the ligaments whose duty it is to hold it up become relaxed, and the unhappy woman suffers all the agonies that are attendant on the "falling of the womb." For this reason the disorder is frequently met with in women who have never borne children as well as in those who have. The Fallopian Tubes.-- The Fallopian tubes extend from the upper, rounded angles of the uterus, within and along the free margin of the broad ligaments, for a distance of about two inches, to the vicinity of the ovaries, where each one terminates in a funnel-shaped orifice surrounded by a series of fringed processes. The lumen of the tube is narrowest at its inner end, where it opens into the cavity of the uterus by a minute orifice which scarcely admits a bristle; the diameter of the canal gradually increases until it reaches its ovarian extremity. The mucous lining of the tube is clothed by a single layer of hair-like epithelium, whose current sweeps from the ovarian toward the uterine end of the tube; and it is these movements which propel the ovum from the ovary to the uterus. The Ovaries.-- The ovaries are two small bodies of an almond shape, and lie on either side of the uterus. The bulk of the entire organ consists of connective tissue, in which lie imbedded the Graafian follicles or ovisacs, in which the ova are contained. These follicles or ovisacs are minute cells which are packed immediately beneath the surface, where they occur in all stages of development. With the increase in size which accompanies their development the follicles pass toward the surface, where they form a distinct projection, and at this point will occur the final rupture of the sac and the escape of the ovum. It is supposed that the ovum is grasped by the fringe-like extremity of the Fallopian tube and is carried through it by the movements of the ciliary epithelium to the uterus.
