...anatomy of the human body, the skin may be considered as composed of two layers, the outer of which is known by various names, as the scarf skin, epidermis, or cuticle. It serves as a covering to protect the true skin beneath it. There are in this epidemis no blood-vessels or sensory nerves. The thickness of this outer skin varies, in different parts of the body, from 1-240 to 1-12 of an inch. This increase in thickness is due, in a measure, to the pressure to which these parts, as the palms of the hands, are exposed...
...walking at the rate of four miles an hour, fives times as much. When walking at the rate of six miles an hour, seven times as much. The increase is shown, perhaps, in a more striking way by Parker, estimating the different amounts in cubic inches. The flow of blood through the lungs is much less rapid when one takes little or no exercise; and the carbonic acid will not be removed from the system in so thorough a manner. If a man then is obliged to lead a life which deprives him of the chance of getting a fair...
...affected by the whole body, it cannot be taken strictly by itself, nor would such a plan be wise. The first effect of exercise on the heart is to increase the number of its pulsations, and the force of each individual one. As a consequence, the flow of blood through the body is increased, including the heart itself, and the waste of the system is washed out more completely and a large supply of fresh material is borne to all parts. While the exercise is within any reasonable bounds, the heart beats increase some twenty or thirty a minute over...
...side, and then splits up into a number of smaller branches. The smallest bronchial tubes at last end in little sacs which are air cells. The walls between them are very thin, and in these walls are the capillary vessels into which the artery bringing the blood from the right side of the heart breaks up. So the blood flowing through them is exposed to the air on both sides. In early life the lungs have a rose color; but as a person grows older, a quantity of black looking matter is found scattered through them, and sometimes forming streaks...
...diseases of the heart depend upon circumstances over which we have no control. In 177 cases of consumption, examined in the Brompton Consumptive Hospital, the heart was found smaller than it should be, in more than one half of the cases. As the heart not only sends the blood through the body, but also receives its nourishment from it, when the food supply is insufficient or of an improper kind, the blood cannot be of the right kind to support the heart in its constant labor. In this way alcohol, by interfering with digestion and destroying the appetite, deprives...
