In the locomotive functions, the bones at once give support, and form levers for motion; the ligaments form articulations, and afford the points of support; and the muscles are the moving powers. To the first, are owing all the symmetry and elegance of human form; to the second, its beautiful flexibility; and to the third, all the brilliance and grace of motion which fancy can inspire, or skill can execute. In the nutritive functions, the food, having passed into the mouth, is, after mastication, aided by mixture with the saliva, thrown back, by the tongue and contiguous parts, into the cavity behind, called fauces and pharynx; this contracting, presses it into the oesophagus or gullet; this also contracting, propels it into the stomach, which, after its due digestion aided by the gastric juice, similarly contracting, transmits whatever portion of it, now called chyme, is sufficiently comminuted to pass through its lower opening, the pylorus, into the intestines; these, at the commencement of which it receives the bile and pancreatic juice, similarly pressing it on all sides, urge forward its most solid part to the anus; while its liquid portion partly escapes from the pressure into the mouths of the absorbents. The absorbents arising by minute openings from all the internal surfaces, and continuing a similar contractile motion, transmit it, now called chyle, by all their gradually-enlarging branches, and through their general trunk, the thoracic duct, where it is blended with the lymph brought from other parts, into the great veins contiguous to the heart, where it is mixed with the venous or returning and dark-colored blood, and whence it flows into the anterior side of that organ. The anterior side of the heart, forcibly repeating this contraction, propels it, commixed with the venous blood, into the lungs, which perform the office of respiration, and in some measure of sanguification; there, giving off carbonaceous matter, and assuming a vermilion hue and new vivifying properties, it flows back as arterial blood, into the posterior side of the heart. The posterior side of the heart, still similarly contracting, discharges it into the arteries; these, maintaining a like contraction, carry it over all the system; and a great portion of it, impregnated with carbon, and of a dark color, returns through the veins in order to undergo the same course. Much, however, of its gelatinous and fibrous parts is retained in the cells of the parenchyma, or cellular, vascular, and nervous substance forming the basis of the whole fabric, and constitutes nutrition, properly so called; while other portions of it become entangled in the peculiarly-formed labyrinths of the glands, and form secretion and excretion--the products of the former contributing to the exercise of other functions, and those of the latter being rejected. As digestion precedes the first, so generation follows the last of these functions, and not only continues the same
