Question
Chapter 20, Problem 8CRCAQ
Summary Introduction
To review:
1. The reason behind the abundance of varicose veins in the lower limbs of the human body.
2. The functional reason behind the less abundance of valves in the veins of the neck region.
Introduction:
The circulatory system is associated with the transportation of blood to the whole body. The long chain of blood vessels are present throughout the body in order to maintain the proper supply of the blood to different body parts. There are separate vessels for the transportation of oxygenated and deoxygenated blood.

Students have asked these similar questions
a) do elastic arteries have an external elastic lamina?
b) compare and contrast the defining features of a muscular and elastic artery (how can you tell them apart)
(a) Explain in your own words why varicose veins are more common in the lower limbs than elsewhere in the body. (b) Give a functional reason why valves are more abundant in veins of the upper and lower limbs than in veins of the neck.
Identify which artery is missing from the following sequence, which traces the flow of arterial blood to the right hand: Blood leaves the heart and passes through the aorta, the right subclavian artery, the axillary and brachial arteries, and through either the radial or ulnar artery to a palmar arch. (a) left coronary, (b) brachiocephalic, (c) cephalic, (d) right common carotid.
