Question
Chapter 20, Problem 3RQ
Summary Introduction
To determine:
The properties of blood vessels that help in the steady flow of blood in capillaries, despite the rhythmic pumping of the heart.
Introduction:
The smallest blood vessels in a human body are the capillaries. They are considered as the vital vessels, due to the functions they perform in the functioning of the circulatory system. The capillaries supply the tissue fluid with necessary nutrients and in turn, take away the carbon dioxide and other nitrogenous wastes from the cells.

Students have asked these similar questions
Blood flow through the capillaries is steady despite the rhythmic pumping action of the heart because of the (a) elasticity of the large arteries only, (b) elasticity of all the arteries, (c) ligamentum arteriosum, (d) venous valves.
(i)List the major blood vessels and their origins involved in coronary circulation.(ii) At what stage or phase of the heart’s activities does the heart tissues becomes perfused with oxygenated blood? (iii) Define myocardial infarction.(iv) Explain the typical signs associated with acute myocardial infarction. (v) Outline/State which arteries of the heart are most commonly affected/occluded.(vi) Explain why occlusions lead to infarct in the heart.
Blood within the veins is prevented from flowing away from the heart because of the presence of: (a) venous reservoirs. (b) muscular walls. (c) clots. (d) valves.
