The capillaries dilate the blood stagnating in them and giving off its oxygen and transuding its fluid elements into the tissues with the result that an insufficient quantity of oxygenated blood reaches the heart to enable it to maintain an efficient circulation. As the sarco-lactic acid liberated in the muscles is not oxygenated a condition of acidosis ensues.
They are neither adaptive changes nor changes towards completion of the type. After noting them we may pass to allied, but still more instructive, changes. Continuous pressure on any portion of the surface causes absorption, while intermittent pressure causes growth: the one impeding circulation and the passage of plasma from the capillaries into the tissues, and the other aiding both.
When they pass in large quantities through the fine pores of the capillaries and accumulate at irritated spots, they cause inflammation. They can consume and destroy bacteria, the dreaded vehicles of infectious diseases; but they can also transport these injurious Monera to fresh regions, and so extend the sphere of infection.
From the quiescence of the anastomosing capillaries a paleness of the skin succeeds, and a less secretion of the perspirable matter; from the quiescence of the pulmonary capillaries a difficulty of respiration arises; and from the quiescence of the other glands less bile, less gastric and pancreatic juice, are secreted into the stomach and intestines, and less mucus and saliva are poured into the mouth; whence arises the dry tongue, costiveness, dry ulcers, and paucity of urine.
Again, what is the ground for arguing that the lips are "full, ripe and red?" The real effect of the emotions that accompany kissing is to empty the superficial capillaries and so produce a leaden pallor. As for such salient symptoms as the temperature, the pulse and the rate of respiration, the learned pundit passes them over without a word. Mrs.
Perhaps the best explanation offered as yet for this passage is that the colloidal substances are changed by the cells lining the capillaries into substances that form true solutions and that after the passage they are changed back again to the colloidal condition.
Blood Pressure at the Capillaries.—The plasma which is forced through the capillary walls by pressure from the heart makes room for itself by pushing a portion of the lymph out of the lymph spaces. This in turn presses upon the lymph in the tubes which it enters. In this way pressure from the heart is transmitted to the lymph, forcing it to move.
To evince that the production of such large quantities of contagious matter, as are seen in some variolous patients, so as to cover the whole skin almost with pustules, does not arise from any chemical fermentation in the blood, but that it is owing to morbid motions of the fine extremities of the capillaries, or glands, whether these be ruptured or not, appears from the quantity of this matter always corresponding with the quantity of the fever; that is, with the violent exertions of those glands and capillaries, which are the terminations of the arterial system.
Robert Clinton cleared his throat and produced a sound bursting with accumulated h's and r's his warning passed unheeded. Never before had Abbott had so much of Fran. The capillaries of his skin, as her hand quivered warmly against his, seemed drawing her in; and as she escaped from her splendid black orbs, she entered his brain by the avenue of his own thirsty eyes.
The irritation sets up reflex uterine contractions, and so the blood is squeezed out of the distended capillaries and washes away the degenerated cells. The third or reparative stage, as its name indicates, is one of repair, in which by constructive changes the epithelial lining which was thrown off is replaced by new, which is formed in from three to four days.
