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.

Physiology of Continuous-Flow Pumps
AACN Advanced Critical Care, 2012The use of mechanical pumps for circulatory support started in the mid-1950s. The evolution of these devices has led to the present-day use of continuous-flow pumps to take over the function of a patient’s failing heart. The physiology associated with rotary blood pump use is quite different from normal cardiovascular physiology.

Wave Phenomena in Physiological Flows
IMA Journal of Applied Mathematics, 1984The aim of this paper is twofold: for a newcomer in the field of physiological fluid mechanics it offers a very short and clear presentation of the one-dimensional theory of pressure waves in elastic tubes (section 2). In this theory the main assumption is the relation between the channel (tube) cross-section area and internal pressure, the so called ...

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.

A semiparametric approach to physiological flow models
Journal of Pharmacokinetics and Biopharmaceutics, 1989By regarding sampled tissues in a physiological model as linear subsystems, the usual advantages of flow models are preserved while mitigating two of their disadvantages, (i) the need for assumptions regarding intratissue kinetics, and (ii) the need to simultaneously fit data from several tissues.

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 ...

THE PHYSIOLOGY OF BONE BLOOD FLOW
The Journal of Bone and Joint Surgery-American Volume, 2006Bone circulation plays an important role in bone physiology, but has been relatively poorly studied, because most techniques of circulatory research are difficult to apply to bone. This article summarizes briefly some of the important aspects of the physiology of bone blood flow most relevant to orthopaedics.The gold standard for experimental ...

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.

The Physiologic Importance of Pulsatile Blood Flow
New England Journal of Medicine, 1962NOT since the time of Hippocrates has the diagnostic value of the arterial pulse been disputed. Yet its role in physiology is considered of little, if any, consequence. Typical of this attitude was Wesolowski's1 statement that "the presence of the pulse may represent nothing more in physiological terms than an expression of the limitations of the ...

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.
