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.

Tell which two veins are missing from the following sequence: Tracing the drainage of superficial venous blood from the leg, blood enters the great saphenous vein, femoral vein, inferior vena cava, and right atrium. (a) coronary sinus and superior vena cava, (b) posterior tibial and popliteal, (c) fibular (peroneal) and popliteal, (d) external and common iliacs.
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.
