Biofliudics has received in value in recent times, forcing engineers to redefine mechanical engineering theories and follow them to organic features. so far, no e-book has effectively performed this. Biofliud Mechanics in Cardiovascular structures is likely one of the first books to take an interdisciplinary method of the topic. Written via a professor and researcher, this e-book will mix engineering rules with human biology to carry a textual content particularly designed for biomedical engineering pros and scholars.

The amount of blood coming from the heart (cardiac output) is dependent on arterial pressure. This chapter deals with the heart and its ability to generate arterial pressure in order to pump blood. The adult human heart has a mass of approximate 300 g. If it beats 70 times per minute, then it will beat ~100,000 times per day, ~35 million times per year, and ~3 billion times (3 ϫ 109) during your lifetime. If each beat ejects 70 mL of blood, your heart pumps over 7000 L, or the equivalent of 1800 gal per day.
The end result is a devastating and sometimes lethal loss of heart function because the blood flow was dependent of a single collateral branch. 11 Microcirculation Microcirculation is the flow of blood in the system of smaller vessels of the body whose diameters are 100 m or less. This includes arterioles, metarterioles, capillaries, and venules. The microcirculation is involved 42 Chapter Two chiefly in the exchange of gases, fluids, nutrients, and metabolic waste products. 1 Capillary structure Capillaries are thin tubular structures whose walls are one cell layer thick.
15. We can apply the Bernoulli equation between points 1 and 2, as well as, the continuity equation as follows. Assume that the Venturi meter is horizontal and that z1 ϭ z2 ϭ 0. 15 A Venturi flow meter with pressure measuring ports at points 1 and 2. 7 Example Problem: Fluid Statics In general, fluids exert both normal and shearing forces. This section reviews a class of problems in which the fluid is at rest. A velocity gradient is necessary for the development of a shearing force, so in the case where acceleration is equal to zero, only normal forces occur.
