    En este capítulo, conocerás la parte vascular del sistema cardiovascular, es decir, los vasos que transportan la sangre por todo el cuerpo y proporcionan el sitio físico donde se intercambian gases, nutrientes y otras sustancias con las células del cuerpo. Cuando se reduce el funcionamiento de los vasos, las sustancias transmitidas por la sangre no circulan de manera efectiva por todo el cuerpo. Como resultado, se produce una lesión tisular, se deteriora el metabolismo y se amenazan las funciones de todo sistema corporal.

    Figura 20.0.1: Vasos Sanguíneos. Si bien la mayoría de los vasos sanguíneos se encuentran a lo profundo de la superficie y no son visibles, las venas superficiales del miembro superior proporcionan una indicación de la extensión, prominencia e importancia de estas estructuras para el cuerpo.
