DESCRIPTION:The presence of cold blood\, whether through acute seasonal ch
 ill or chronic environmental exposure\, imposes an additional burden on th
 e hearts’ ability to pump viscous blood around the body\, potentially li
 miting blood flow to working muscle. Of particular interest is how the ‘
 business end’ of the cardiovascular system\, the microcirculation\, adap
 ts under these conditions. Here\, intimate contact between blood and tissu
 e is achieved by a vast network of tiny vessels (capillaries) that facilit
 ate supply of oxygen and other fuels\, as well as removal of waste product
 s. This lecture will explore some strategies that warm-blooded animals use
  to cope during winter\, and contrast this with adaptations seen in cold-b
 looded animals that thrive in the constantly frigid waters around Antarcti
 ca.\n\nStuart Egginton is a cardiovascular and muscle physiologist at the 
 University of Leeds\, where he is Professor of Exercise Science. His work 
 explores biological limits to activity\, and how flexibility is essential 
 to cope with physiological challenges. He is a Fellow of The Physiological
  Society\, currently a Monitoring Editor for the Journal of Experimental B
 iology\, and has served as President of the British Microcirculation Socie
