Circulation

THIS is the first of three volumes on the circulation which will make up the second section of the Handbook of Physiology. It follows the first section of three volumes on neurophysiology and will be followed by further sections covering respiration, renal physiology, endocrine physiology, etc. The concept of the Handbook is a very important landmark in the development of physiological literatu...

Tracheal Chondrosarcoma Excised With Extracorporeal Circulation

Introduction: Tracheal chondrosarcoma (TCS) is a rare malignancy, with only 19 cases described in the literature to date. Case presentation: Herein, we presented the third-largest TCS with such an airway compromise that neither orotracheal intubation nor jet ventilation or even tracheostomy was possible. So, extracorporeal circulation was needed to excise the tumor in a one-stage procedure. Th...

Ocean Circulation

The ocean moderates the Earth's climate due to its vast capacity to store and transport heat; the influence of the large-scale ocean circulation on changes in climate is considered in this chapter. The ocean experiences both buoyancy forcing (through heating/cooling and evaporation/precipitation) and wind forcing. Almost all ocean forcing occurs at the surface, but these changes are communicate...

Arterial Circulation

Adenosine is a potent vasodilator used extensively to study the coronary circulation of animals. Its use in humans, however, has been hampered by lack of knowledge about its effects on the human coronary circulation and by concern about its safety. We investigated in humans the effects of adenosine, administered by intracoronary bolus (2-16 jig), intracoronary infusion (10-240 ,ug/min), or intr...
