Flowmeter for slow-flowing physiological liquids
Medical & Biological Engineering & Computing, 1984We have developed a device to measure continuously the slow flow of fluid secreted by the fungs of foetal lambs. Typically this fluid flows along the trachea at 5–10 ml kg−1h−1 Intermittent retardation of flow is thought to facilitate prenatal lung development.

It is in only a few centers that tissue fluid and lymph hydraulics have thus far been studied under normal conditions in the soft tissues of the human limb and in lymphedema.1 - 9 Although knowledge of extravascular fluid hydraulics is indispensable for understanding the manual and pneumatic massage events in tissues and after surgical lymphatico ...

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%.

Fluid-Structure Interaction in Internal Physiological Flows
Annual Review of Fluid Mechanics, 2011We provide a selective review of recent progress in the analysis of several physiological and physiologically inspired fluid-structure interaction problems, our aim being to explain the underlying physical mechanisms that cause the observed behaviors.

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.
