TL;DR: The dynamics of lymphatic pumping have been investigated experimentally and mathematically, revealing complex behaviours indicating that the system performance is robust against minor perturbations in pressure and flow.

TL;DR: A simple, third-order lumped parameter model is presented to describe unsteady flow in a short segment of collapsible tube held between two rigid segments and contained in a pressurised chamber, focusing on the mechanical properties of the parts of the system both downstream and upstream of the collapsible segment.

TL;DR: In this paper, the authors investigated aqueous flow through silicone rubber tubes held open at both ends and externally pressurized, and found that the tube oscillations can be divided into well-separated bands of low, intermediate and high frequency, within each of which the frequency generally increases gradually with flow-rate and external pressure.

TL;DR: The extraparenchymal pulmonary veins act as a reservoir to the left atrium so that left ventricular stroke volume can be maintained relatively unaffected by beat by beat changes in right ventricular strokes, which could otherwise impede venous outflow of blood from the lung capillary bed.

TL;DR: A potential relationship between the associated turbulence-induced vein-wall vibration and the development of intimal hyperplasia in arteriovenous grafts is suggested.
