Biofluid Mechanics. Principles and Applications by Ali Ostadfar

By Ali Ostadfar

Biofluid Mechanics is a throrough connection with the whole box. Written with engineers and clinicians in brain, this e-book covers body structure and the engineering features of biofluids. successfully bridging the distance among engineers’ and clinicians’ wisdom bases, the textual content presents details on body structure for engineers and knowledge at the engineering part of biofluid mechanics for clinicians. scientific functions of fluid mechanics rules to fluid flows during the physique are incorporated in each one bankruptcy.

All engineering innovations and equations are built inside a organic context, including computational simulation examples in addition. content material coated contains; engineering types of human blood, blood rheology within the movement process and difficulties in human organs and their unwanted side effects on biomechanics of the cardiovascular approach. the knowledge contained during this booklet on biofluid rules is middle to bioengineering and clinical sciences.

  • Comprehensive assurance of the full biofluid mechanics topic will give you an multi functional reference, removing the necessity to collate details from assorted sources
  • Each bankruptcy covers rules, wishes, difficulties, and strategies so as to assist you establish power difficulties and hire solutions
  • Provides a singular breakdown of fluid move by means of organ approach, and a short and centred reference for clinicians

In the negative case, other Rh antigens can still cause mild transfusion reactions [20]. 3 Blood Cells A hematocyte or blood cell is a cell is produced from an hematopoietic stem cell in the bone marrow. 1 Erythrocytes (RBCs) The major function of erythrocytes (RBCs) is to transport hemoglobin, which in turn carries oxygen from the lungs to the living tissues. Besides the transport of hemoglobin, RBCs have other roles in human body, such as increasing the rate of CO2 carrying by water in the blood and assisting in acidÀbase buffering of hemoglobin [20,24].

Fibrinogen: plays a key role in clotting and production of fibrin. Its plasma concentration is 150À300 mg/dL. The liver synthesizes fibrinogen. Globulins: participate in the immune system. 5 g/dL. Most globulins are synthesized by liver. Coagulation factors: participate in the conversion of fibrinogen to fibrin. The liver synthesizes most coagulation factors. 7 Blood Viscosity and Its Aspects One of the important assumptions in the Poiseuille equation is the Newtonian fluid condition. Generally, biofluid mechanics and medicine use this equation for cardiovascular problems and usually the viscosity of whole blood is considered constant in a Newtonian sense.
