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.

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
An embolus is a blood clot that has broken loose and travels in the circulation. If an embolus lodges in an artery and obstructs blood flow, it forms an embolism. Explain some of the dangers of embolisms.
In flowchart form, trace the pathway of the blood in the systemic circulation. (Example: Trace the flow of blood from the tongue to the right thigh. Note that the blood also passes the pulmonary circulation)

What will it do?arrow_forwardThe aorta, the largest artery in the body (in diameter), carries oxygen-rich blood away from the heart as it begins the systemic blood flow circuit throughout the body. Owing to the fact that the aorta connects directly to the heart, the blood pressure (BP) inside the aorta is very high. As blood travels further from the heart, the BP gradually decreases. For example, the BP in the aorta is higher than in the brachial artery; the BP in the brachial artery is greater than in the antecubital artery; the BP in the antecubital artery is greater than in the radial artery. Based on the understanding that walls of the aorta are subjected to extreme outward pressure, hypothesize the order of specific tissue types one would expect to find in the aorta (from deep to superficial) and explain your rationalearrow_forwardArterioles are often referred to as resistance vessels.Why?arrow_forward
