THE CIRCULATORY OR VASCULAR SYSTEM 12$ 



The radial vein starts at the back of the wrist, 

 receiving tributaries from the deep veins of the palm, 

 and connects with the several venous branches from the 

 fingers and thumb, where it 

 is increased in size; it passes 

 on upward, and at the bend 

 of the elbow it runs forward 

 and unites with the median 

 cephalic to form the cephalic 

 vein. 



The cephalic vein passes 

 upward on the outer side of 

 the arm and terminates in 

 the axillary vein. 



.The median vein takes its 

 start at the wrist and palm 

 of the hand; at the elbow it 

 receives other branches from 

 the deep structures, and 

 divides into two branches 

 the median basilic and me- 

 dian cephalic. 



The median cephalic 

 unites with the radial to 

 form the cephalic vein. 



The median basilic unites 

 with the ulnar to form the 

 basilic vein. 



The deep veins of the upper 

 extremity follow the course 

 of the arteries. They have numerous anastomoses, 

 not only with one another, but with the superficial 

 veins. 



The axillary /vein is formed by the union of the 

 brachial ve#ae comites with the basilic; it also receives
