EXERCISE 83 

 THE FLOW OF BLOOD IN THE ARTERIES 



Directions. Most of the arteries lie deep in the tissues, but they may be recognized by their 

 V beat;" Examine the right-hand wrist with the tip of the finger and locate the artery on the palm 

 side of the wrist near the base of the thumb. Locate the arteries of both wrists. Count the number 

 of beats per minute. Repeat to verify. Find also the carotid artery in the side of the neck, the 

 small artery at either side of the nose just below the eye, and the artery just in front of the ear. 

 What is the average number of heartbeats per minute for your entire class ? What are the greatest 

 individual variations ? 



Additional problems. When an injury results in cutting a large blood vessel, how can you distinguish 

 whether it is an artery or a vein ? 



If an artery were cut at the elbow, where should the bandage be placed in order to stop the bleeding ?
