“La vasodilatation des vaisseaux sanguins périphériques désigne le phénomène d’augmentation du diamètre des capillaires sanguins, augmentant la circulation du sang vers la périphérie du corps humain.
\nElle est due à un réflexe du corps humain en réponse à de chaudes températures.
\nElle a pour conséquence de :
\n– augmenter les échanges thermiques dans ces zones (ce qui n’est pas gênant si l’eau est chaude),
\n– déconcentrer la circulation sanguine, depuis le thorax vers l’ensemble du corps humain, créant momentanément une dépression au niveau du cœur.
\nLe phénomène inverse s’appelle la vasoconstriction<\/a> des vaisseaux sanguins périphériques.
