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.

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 ...

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.

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.

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 ...

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 ...

The lymphatic system is an elaborate network of vessels that act harmoniously to pump fluid and cells, collectively called lymph, from the interstitial space into the blood circulation. The journey of lymph begins with the extravasation of fluid and cells from the blood capillaries into the interstitium. These are then taken up by the initial lymphatic

The calculation of entrance length in physiological flow
Medical & Biological Engineering, 1975Entrance length is proportional to the square of the thickness δ of the oscillating boundary layer on the walls of the tube. Values of δ calculated for a rigid tube of circular cross-section are presented. Entrance length is important because of the multiple branching of the vascular network.

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 ...

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.
