The gray iris grew luminous, he noticed, while her face was flooded with color, as ...

... prepared for. As the foetus develops there is a corresponding development of the muscular wall of the womb. The last period of pregnancy is characterized by the relaxation of the muscles and ligaments that form the pelvic walls, and a relaxation and dilation of the maternal passages. In addition, degenerative changes occur in the structures that attach the foetus to the womb, the normal structures being gradually destroyed by a fatty degeneration.

... the only thing which the black bear really feared. Often as he had visited them, to catch wounded fish in the ominous eddies at their foot, he could never look at their terrific plunge without a certain awed dilation of his eyes, a certain shrinking at his heart. Perhaps by reason of some association of his cubhood, some imminent peril and narrow escape at the age when his senses were most impressionable, in all his five years of life the Falls had never become ...

For I could neither rightly perceive at first when the systole and when the diastole took place, nor when and where dilation and contraction occurred, by reason of the rapidity of the motion, which, in many animals, is accomplished in the twinkling of an eye, coming and going like a flash of lightning. At length it appeared that these things happen together or at the same instant: ...

She caught a glint in his eye less like confusion than resentment, and saw a dilation of his nostrils which might have indicated not so much a sweet agitation as an inaudible snort.

For after much easy practice on Mr. Spinks she knew precisely by what movements and what glances she could best produce these interesting effects. And yet nothing could be farther from Flossie's fancy than flirtation. The little clerk was nothing ...

The face was perfectly oval; the nose, though small was high and aquiline, and exhibited a remarkable dilation of the nostril; the curling lip was shaded by a very delicate mustache; and the general expression, indeed, of the mouth and of the large grey eyes would have been perhaps arrogant and imperious, had not the extraordinary beauty of the ...

These connect with neurons that in turn connect with blood vessels and with them act reflexively, when the heart is likely to be overstrained, to cause a dilation of the blood vessels.
