Summary Introduction

To review:

Dependence of resistance in the vessels on its length.

Introduction:

The vasodilation and vasoconstriction regulate the blood flow rate through the arteries and arterioles. The vasoconstriction raises the resistance towards blood and decreases the blood flow whereas, the vasodilation makes the resistance to decline and elevates the blood flow.

A) Perform an analysis of the stenosed artery diameter D and lengtn c using the Bernoulli equation to determine an expression for the pressure drop across the segment of artery for a blood flow rate (Q). Create a well labelled diagram indicating the area of analysis and variable names and state all relevant assumptions made in your analysis. You snould assume that the stenosis creates a rapid narrowing of the artery, and that friction is not negligible. B) Explain how your analysis would change following insertion of the stent.
Blood velocity is slowest in the capillaries  A. Explain the mechanics of why blood slows down in these blood vessels (objective N) B. What would happen if blood velocity was fastest in the capillaries?
(27.1) The aorta is the body's major arterial blood vessel. A reasonable value for the (circular] diameter of the aorta in a healthy adult is D, 4.0 cm. The blood in the aorta moves with an average (uniform] speed v, 30 ca/s. The blood flowing through the aorta passes through capillaries spread throughout the tissues in the body and then is recirculated. The typical diameter of one of these capillaries is D. 4.0 um = 4.0 x 10- , and the blood flows at approximately 1.0mm/s. Estimate the number of capillaries in a healthy adult.
