A further question to be considered is the relationship between the metab-olism of one tissue and the products of the metabolism of other metabolism of one tissue may produce products, proteid or otherwise,which when taken up by the blood and carried to other tissues supply ex-actly what is necessary for their complete anabolism. The physiology of the internal secretions has revealed a number of suchinfluences that are best explained on the assumption of the presence of spe-cial products. The Thyroid. The thyroid gland is situated in the neck. It con-sists of two lobes, one on each side of the trachea, extending upward to the. Fig. 311.—Part of a Section of the Human Thyroid, a.

The 428 METABOLISM, NUTRITION, AND DIET thyroid is covered by the muscles of the neck. It is highly vascular, andvaries in size in different individuals. The gland is encased in a thin transparent layer of dense areolar tissue,free from fat, containing elastic fibers. These gland vesicles are each lined with a single layer of cubical cells andare filled with transparent nucleo-albuminous colloid material. Accessory Thyroids. The accessory and the parathyroids possessthe structure of the thyroid and apparently
