Respiratory and cardiac physiology

Modelling of physiological systems at the large (body) scale often involves the ideas of control, since the feedbacks involved in maintaining homeostasis often have this role. Different such systems which are of current interest are the cardiovascular circulation, the respiratory system, and the production of blood cells. The models all typically involve differential-delay equations, and in certain diseased states, oscillations occur which are thought to be due to instability in these delayed feedback models.
