and branches ramify throughout all the substance of this 

 organ. 



The outer branch of the .carotid goes to the outside of 

 the head and to the face. It sends branches to the forehead, 

 the cheeks, the chin, the lips, and the other parts of the face 

 All these organs are thus supplied very abundantly with blood 

 by these vessels and their numberless little branches. (Fig. X.)

214. The aorta is divided in the lower part into two great 

 branches, (Fig. XL e, e.) These two branches pass through 

 the groins, where they are called inguinal arteries, and thence 

 into the thighs, where they are the femoral arteries ; passing 

 downward, they divide, and send branches to the flesh of the 

 lower limbs, until the legs, the feet, and the toes are sup- 

 plied with them. 



All these arteries in every part of the body are divided 

 and multiplied as they go from the heart, and their num- 

 berless small branches are distributed into every part of 

 the flesh in all the organs and regions of the body. Thus 

 all the parts, organs, and textures are supplied with blood 

 for their nourishment.
