Cerebral blood flow and vascular physiology
Anesthesiology Clinics of North America, 2002The cerebral circulation is tightly regulated to meet the brain's metabolic demands. Although the mechanism is not fully understood, the major physiologic influences on cerebral blood flow have been well documented. In this chapter the basic vascular anatomy, and physiologic control of the cerebral circulation are reviewed.

Coral physiology: Going with the ciliary flow
Current Biology, 2022Corals have long been known to generate local fluid flows using ciliary beating, but the importance of these ciliary flows is just being discovered. Two new papers shed light on how ciliary-flow physics plays a key role in shaping coral physiology.

Modeling of physiological flows
2012This book offers a mathematical update of the state of the art of the research in the field of mathematical and numerical models of the circulatory system. It is structured into different chapters, written by outstanding experts in the field. Many fundamental issues are considered, such as: the mathematical representation of vascular geometries ...

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 ...

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.
