The CNRS Cerebrovascular Research Laboratory has designed a new process for visualisation of brain blood flow using laser-scanning confocal fluorescence microscopy. The film uses cinemicrography images...
An interactive tutorial for teaching the basic physiology of the blood vessels, blood flow and regulation of blood pressure. Introduces the structure and function of the circulatory system and the...
Looks at how the heart responds to the demands from the tissues in various physiological situations. During exercise changes in blood flow can be achieved not only by an increase in heart rate, but by a...
A patient presents with a seemingly minor transient ischaemic attack. Various methods of investigating cerebral blood flow are shown and, in this case, serious occlusion of the carotid vessels is revealed. A...
Describes the regulations and disturbances of blood flow, blood pressure and cardiac function. Concentrates on understanding rather than detail and uses analogies with other transport systems and clinical...
1: The pressure of a column of blood, Bernouilli’s principle, Poiseuille’s Law, Reynold’s number, Laplace’s law, arteries, vascoconstriction and vasodilation, triple response. 2: Veins - the venous...
Factors governing flow in rigid tubes, critical closing pressure, Poiseuille’s Law, driving pressure and transmural pressure, the effect of elasticity of blood vessels. Laplace’s Law, the effect of a...
A summary of a lesson designed to introduce a certificate class to the basic points of a closed circulatory system. The microscopic views the pupils are expected to see at each stage are included.
Statistical statement of the Fick principle, measurement of cardiac output using the Fick principle, measurement of liver blood flow using bromsulphthalein, measurement of brain blood flow using nitrous oxide.
A considerably edited programme showing the preparation of an anaesthetised dog for measurement of arterial blood pressure, heart rate, aortic blood flow, left ventricular contractility. Responses to...
