Question
Chapter 23, Problem 2DCR
Summary Introduction
To determine:
The reason for the presence of more vascular anastomoses of arteries around the joints in the body of an individual.
Introduction:
Presence of arteries is deep beneath the skin. They supply the tissues with blood rich in oxygen. Areas having interrupted arterial network receive less supply of oxygenated blood. This creates a hypoxic condition in the tissue leading to its improper functioning.

Arteries tend to have a lot of vascular anastomoses aroundbody joints (such as the elbow and knee). Propose a reason whythis would be beneficial.
Based on the Image below make a simple explanation (be unique, you can present it through diagrams or shapes) about the flow of blood into and from the heart.
Which is the main structural feature that distinguishes elastic arteries from muscular arteries?
Answers A -E
A Elastic arteries have a significantly higher quantity of elastic fibres in the tunica media than muscular arteries
R Muscular arteries do not have any elastic fibres, whereas elastic arteries are rich in elastic fibres
Muscular arteries have muscular cells only in the media, whereas elastic arteries do not have any
Muscular arteries have muscular cells throughout their wall, whereas elastic arteries do not have any
E Muscular arteries have vasa vasorum, elastic arteries do not
