Blood Flow and Thrombosis [PDF]
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 American Journal of Digestive Diseases, 1963 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.

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.

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.

Blood flows and magnetohydrodynamics
2009In order to improve the quality of the images provided by Magnetic Resonance Imaging (MRI), the magnetic field used in MRI is getting larger and larger: from 3T nowadays, it might increase in the future up to 10T in clinical scanners. The impact of such a large magnetic field on health is still in debate.

Hence does arise the action and function of the heart, which by pulsation it performs. [William Harvey, De Motu Cordis, 1628.] THE study of blood flow as a pulsatile phenomenon is scarcely new, but it has gained new impetus from three recent developments: the commercial production of reliable blood flowmeters, the formulation of theories appropriate to

In ophthalmology, laser-Doppler velocimetry (LDV) has been used for various types of measurements besides those of blood velocity. For example, it has been applied to investigate eye motion during smooth pursuit of a target [1] and the mechanical compliance of the optic nerve head [2].

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.
