characteristics of the distribution of

The the arteries

a. the larger arteries usually occupy hidden locations in the limbs, running along the flexor surfaces to avoid injury. b.They are segmental and intersegmental in character. The intersegmental character of the intercostals and lumbar vessels is obvious. c.The intersegmental arteries and vein are bilaterally symmetrical vessels d.The arteries in the trunk of body can be divided into the parietal and visceral branches. The parietal branches are distributed to the walls of the body, and the visceral to the internal organs. e.Many of arteries, veins and nerves are enclosed together in a sheath of fascia.
