An Electromechanical Flow Transducer for Physiological Fluids
Physics in Medicine & Biology, 1966A simple method, based on conductivity measurement, has been developed to obtain an electrical output from a rotameter flowmeter. The ancillary equipment required is relatively simple and inexpensive. The reproducibility of readings throughout the day is generally better than ±2% and never worse than ±5%.

Flow Structures in Physiological Conduits
2011The study of topological structures in the case of a peripheral planar bypass graft and a cerebral aneurysm are presented. The Taylor series expansion of the velocity field to first order terms leads to a system of ODEs, the solution to which locally describes the motion of the flow.

Renal physiology of the pig: Application of stop-flow
Comparative Biochemistry and Physiology Part A: Physiology, 19901. The stop-flow method in the pig, with modified kidneys, produced patterns for sodium, chloride, glucose and PAH that were similar to those obtained previously in other animals with simple kidneys. 2. Ethacrynic acid, under the conditions of the experiment, abolished distal sodium and chloride reabsorption in the pig. 3. We conclude that this method,

A physiological model of cerebral blood flow control
Mathematical Biosciences, 2005The construction of a computational model of the human brain circulation is described. We combine an existing model of the biophysics of the circulatory system, a basic model of brain metabolic biochemistry, and a model of the functioning of vascular smooth muscle (VSM) into a single model. This represents a first attempt to understand how the numerous

Physiology of Coronary Blood Flow
2015Coronary blood flow is responsible for providing nutrients and oxygen to the heart thus enabling it to pump blood to itself and the rest of the circulatory system. Given this important task, oxygen supply must be matched very closely to the demands of the myocardium.

Physiology and Pathophysiology of Arterial Flow
2014Arterial flow is a three-dimensional unsteady process that is analyzed by measurements as well as physiological, biological, and mechanical experiments and numerical simulations. Few quantities can be noninvasively measured; they encompass cardiac frequency and peripheral arterial blood pressure as well as velocity and flow rate in given arterial ...

Physiology of Cerebral Blood Flow
Abstract Cerebral blood flow (CBF) is tightly regulated regionally via multiple processes including the neurovascular unit which consists of perivascular nerves, endothelium, and astrocytes working together to regulate CBF, autoregulation which allows the brain to maintain a constant CBF despite changes in blood pressure, flow ...Ossama Khazaal, W.

Physiology and Pathophysiology of Venous Flow
2015Veins provide heart filling flow with lower velocity and pressure than those in arteries. The right heart receives systemic venous blood and pumps blood into the pulmonary circulation that returns oxygenated blood into the left heart for its ejection at high velocity and pressure into the systemic circulation.Whereas systemic veins carry deoxygenated ...
