The branches of the great artery of the body, the aorta, supplying the abdomen and pelvis, are larger in woman than in man, as well as more habitually liable to variation in the quantity of their contents. The quantity of blood, also, which passes to the abdomen, is greater. At the same time, the excretions are generally less in woman. Hippocrates says: "_Nam corpus muliebre minus dissipatur quam virile_;" the expenditure of the body of woman is less than that of man. It is evident, then, that the secretions, nutrition, in particular, must be greater. We actually know them to be so. But the nourishment of the organs concerned in locomotion is less active, and that of the cellular and adipose substance is generally more active, than in man. And on this, important consequences depend. Woman is subject to crises which would destroy all her organs, if they offered too powerful a resistance. Some parts of her body are exposed to great shocks, to alternate extensions, compressions, and reductions, which could not take place with impunity, but by means of this predominance of the cellular and adipose structure. The cellular expansion, the general basis of the structure, appears then to be more abundant in woman, more lax and yielding, more dilated and fuller of liquids; and it is by yielding gradually, by decomposing and weakening shocks by means of the general suppleness of the different organs, thus procured, that nature seems, in woman, to avoid, or to destroy, every hurtful effort. It is observed, moreover, that certain parts, naturally more loose, receive into all their vessels a more considerable quantity of liquid, and assume a particular enlargement, at the moment when their sympathy with the uterus causes them to enter into action in concert with it; and it is also observed that they dilate more easily during pregnancy. It is thus, then, that nature gives to all the parts of woman that suppleness which renders her capable of easily yielding to the great revolutions which affect her organization in regard to reproduction, as well as mark the different periods of her life. The great development of the cellular and fatty tissue in woman is illustrated by the remarkable fact, that anciently the Romans, in order to burn the bodies of dead men, were obliged to join to them those of women, the fat of which greatly facilitated combustion. Now, with the great purposes described above, beauty is naturally associated. It is principally this excess of the cellular and fatty tissues which gives to the members of woman those round and beautiful outlines, that soft and polished surface, which the body of man does not possess.
