In this paper pulsatile blood flow through rigid circular tubes due to a sinusoidally varying pressure gradient is analyzed using a microcontinuum model of blood. A new boundary condition, which is in accord with experimental observations on blood flow in small rigid tubes, has been proposed to describe red blood cell rotations at a solid boundary ...

American Journal of Physiology-Endocrinology and Metabolism, 1982
The direction of pituitary blood flow, the amount of pituitary blood flow, its regional control, and the role of the median eminence microcirculation are the subjects of this review. Present concepts of pituitary blood flow are focused almost entirely on its direction and arouse from studies of pituitary vascular anatomy performed almost 50 years ago ...

To the Editor.— Hansen and co-workers1 have taken the time to address a question of considerable import, ie, whether the use of Doppler continuous wave forms provides a means of reflecting changes in brain blood flow when the anterior cerebral artery is used.

Autoregulation of cochlear blood flow
European Archives of Oto-Rhino-Laryngology, 1991The cochlear blood flow of healthy adult guinea pigs was measured with a laser Doppler flowmeter and flow dynamics were analyzed on the basis of autoregulation. Angiotensin II infusion was used to raise blood pressure, while phlebotomy was done to lower blood pressure. The characteristics of autoregulation of cerebral blood flow and muscular blood flow

1. The intramural blood vessels of the human colon have been described. 2. Five methods that have been used to study colonic mucosal blood flow in patients with colostomies or with normal colons were briefly outlined along with some of the limitations of each technic. 3.

Abstract Pulmonary hemodynamics is studied in terms of the quasi one-dimensional unsteady nonlinear fluid flow equations which are applied to the 40-odd generations of branched arterial, capillary and venous distensible vessel segments making up the four lobes of the complete lung.

Thrombosis and Haemostasis, 1974
SummaryPlatelet thrombi have been observed at bifurcations, constrictions and stenoses in the arterial tree where flow separation with accompanying vortex formation can occur. Hence, studies of the flow behavior of human blood cells in models of à vessel obstruction and a sudden expansion of a vessel lumen were carried out.

The Flow of Blood in the Capillaries
Physics in Medicine & Biology, 1968A model consisting of right circular cylinders moving through a tube is chosen to represent the flow of corpuscles through the capillaries. A numerical solution of the equations of motion enables the flow to be considered in detail. The pressure gradient-volume flux relationships are calculated for different values of the parameters of the system. Flow
