Suppose the nerves that supply the lungs with motion should stop, the lungs would stop also; suppose they should half stop, the lungs would surely half stop. Now we must reason, if we succeed in relieving lungs, that all kinds of nerves are found in them. The lungs move, thus you find motor; they have feeling, thus the sensory; they grow by nutrition, (thus the nutrient nerves;) they move by will, or without it; they have a voluntary and involuntary system; they move in sleep by the involuntary system. The blood supply comes under the motor system of nerves, and delivers at proper places for the convenience of the nerves of nutrition. The sensory nerves limit the supply of arterial blood to the quantity necessary, as the construction is going on by each successive stroke of the heart. They limit the action of the lungs, receive and expel air in quantities sufficient to keep up purity of the blood, etc. With this foundation we observe if too great action of the motor nerves, shows by breathing too often to be normal, we are admonished to reduce breathing by addressing attention to the sensory nerves of lungs, in order that the blood may pass through the veins, whose irritability has refused to receive the blood, farther than arterial terminals. So soon as sensation is reduced relaxation of nerve fibers of veins tolerates the passage of venous blood, which is deposited in the spongy portions of the lungs in such quantities as to overcome the activity of the nerves of renovation that accompanies the fascia in its process of ejection of all fluids that have been detained an abnormal time, first in the region of the fascia, then in the arterial and venous circulation. Thus you see what must be done. The veins as channels must carry away all blood as soon as it has deposited its nutrient supplies to the places for which it is constructed, otherwise, by delay vitality by asphyxia is lost to the blood which calls a greater force of the arterial pumps to drive the blood through the parts, ruptures its capillaries and deposits the blood in the mucous membrane; until nerves of the fascia becomes powerless by surrounding pressure, which causes through the sensory nerves an irritability at the heart, which puts in force all its powers of motion. TUMEFY, TUMEFACTION. Webster's definition of tumefaction is to swell by any fluids or solids being detained abnormally at any place in the body.
