...Carol A. Gibbons; Robert E. Shad Wick ABSTRACT This study examines the importance of vascular elasticity to arterial haemodynamics in a poikilothermic vertebrate. Pulsatile blood pressure, flow and vessel diameter were recorded at several locations within the arterial tree of the toad, Bufo marinus...

... Octopus elasticity haemodynamics Windkessel The elasticity of the artery wall provides a passive mechanism for smoothing the pulsatile flow of blood from the heart to peripheral sites. In mammals it has long been recognized that this property is an important determinant of haemodynamic...

... represented less than 1 % of the wavelength of the fundamental pulse frequency, due to the low heart rate in this species. Consequently, arterial haemodynamics in O. dofleini are dominated by strong wave reflections, but do not exhibit other wave propagation effects which are typical of mammalian circulatory...

... rectal gland haemodynamics salt secretion blood flow An intimate relationship between secretion rate and blood flow is a widely reported feature of a variety of exocrine glands; a marked vasodilation, synchronous with a stimulation of secretion rate, has been described in several such tissues...

... the haemodynamic effects of catecholamines and known secretory agents on the isolated perfused rectal gland. It is known that the elasmobranch rectal gland secretes sodium and chloride ions at a concentration approximately twice that of the plasma ( Burger & Hess, 1960 ). On ap propriate stimulation...
