If we then return the blood to the system, the animal is as suddenly revived.It is none the less essential to health, however, that the blood should have its proper constitution.Carefully performed, it is very striking.Its immediate importance to life can be beautifully demonstrated by experiments upon inferior animals.The flrst cause of these conditions may lie in a disordered state of the blood, from bad nourishment, from the introduction of poisons, such as malaria, NFL Jerseys Cheap , NFL Jerseys Sale or the emanations from persons affected with contagious diseases, and under some circumstances the elimination of these poisons may be effected through the blood; but when they exist in the blood, they either become fixed in the system, or are thrown off.If we take a small dog, introduce a canula through the right jugular vein into the right side of the heart, adapt to it a syringe, Cheap GHD Hair Straighteners , NFL Jerseys Wholesale and suddenly withdraw a great part of the blood from the circulation, immediate suspension of all the vital processes is the result.
Transfusion.We must regard most of the morbid actions which are dependent on diathesis, GHD Straighteners , GHD Hair Straightener as the result of a vice in the tissue itself, not the blood with which it is supplied.
NFL Jerseys Authentic , NFL Jerseys Youth It must be remembered that in nutrition the tissues are active, selecting, appropriating, and modifying material which is simply furnished by the blood ; and as the real vital force which governs these processes resides in the tissues, tendencies of the system, such as the tubercular, scrofulous, or cancerous diatheses, which lead to disordered nutrition, must have their seat in the solids, and not in the circulating fluid.1 To perform this experiment satisfactorily, we must accurately adjust the capacity of the syringe to the size of the animal.The final importance of the blood in the processes of nutrition is evident; and in animals in which nutrition is active, death is the immediate result of its abstraction in large quantity.
