Blood is the fluid which flows in the cardiovascular system. It is, however, not a pure fluid but rather a suspension of a number of different particles (cells, cell fragments and macromolecules) in a fluid base. This chapter explores the fluid behaviour of blood including the impact of the particles on this behaviour.

In summary, the vascular bed of the stomach is an area of great potential importance to both gastric and vascular physiologists. There are available many technics for its investigation. Simultaneous study of both hemodynamic and secretory phenomena can be conducted on the stomach.

Glaucoma, one of the leading causes of blindness in the world, is characterized by progressive visual field loss and distinctive excavation of the optic nerve head. Although elevated intraocular pressure is the major risk factor, there is increasing evidence that the pathogenesis of glaucoma is also linked to altered ocular blood flow.

Abstract In this paper the theory of micropolar fluids with stretch is used to analyze blood flow in comparatively small arteries, say 100 μ dia. Physically micropolar fluids with stretch can provide a mathematical model to represent blood with its deformable substructure, since not only the independent rotation of red cells but also the flexibility ...

To the Editor.— Doppler ultrasound assessment of flow velocity in cerebral vessels in neonates has generated intense interest since the technique was originally applied to the preterm infant by Bada et al.1 The value and indication both as a research tool and useful clinical tool have yet to be defined.

Pediatrics, 1982
In the commentary, "Pulsatility Index, Patent Ductus Arteriosus, and Brain Damage," It was stated that we have shown that "blood flow" to the brain was not reduced in premature lambs with left-right ductal shunting. The abstracted data referred primarily to alteration of the percent distribution of blood flow and not to changes of absolute blood flow ...

Traditionally, Doppler ultrasound has been used to estimate blood flow as the mean velocity multiplied by the vessel area, but this is subject to significant errors and may be difficult to perform accurately. Microbubbles, developed as contrast agents for ultrasound, were initially envisaged as useful for increasing the intensity of echoes and thus ...

Perfusion, 1995
We have reviewed briefly some features of the mechanics of blood flow, focusing particularly on the arterial system. Among the topics we consider are: steady and nonsteady flow in straight rigid tubes; the curvature and branching of arteries, noting that it may commonly be nonplanar; and the effects of both planar and nonplanar curvature and branching ...

The rigidity of the skull and the inertial characteristics and incompressibility of its contents cause the elastic cerebral arteries and veins to act over brief periods of time like rigid tubes of relatively small diameter. Poiseuille's law is applicable to their behavior.
