Seals control internal temperatures and reduce heat loss by what is called "countercurrent heat-exchange." As an example, the arteries carrying warm blood to the tail fins are meshed with the veins carrying cold blood from the tail. Inside this mesh, heat is transferred from the arteries to the veins, moving heat to the returning blood rather than losing it to the ocean. (As focas controlan as temperaturas internas e reducen a perda de calor polo que se denomina "intercambio de calor contracorrente". Como exemplo, as arterias que levan sangue quente ás aletas da cola están mesturadas con veas que traen sangue frío desde a cola. Dentro desta rede, a calor transfírese desde as arterias ás veas, movendo a calor ao sangue que retorna en vez de perdela no océano.)
