Los pulpos tienen tres corazones: dos corazones branquiales bombean sangre a trav\u00e9s de cada una de las dos branquias, mientras que el tercero es un coraz\u00f3n sist\u00e9mico que bombea sangre a trav\u00e9s del cuerpo. El coraz\u00f3n sist\u00e9mico est\u00e1 inactivo cuando el animal est\u00e1 nadando. La sangre del pulpo contiene la prote\u00edna hemocianina, rica en cobre para transportar ox\u00edgeno. Esto hace que sea muy viscosa, siendo cuatro veces m\u00e1s densa que el agua. Los pulpos tienen presiones sangu\u00edneas muy altas, que pueden exceder de los 7 mmHG. Al igual que los vertebrados, los vasos sangu\u00edneos de los cefal\u00f3podos pueden mantener la presi\u00f3n arterial. Aunque es menos eficiente en condiciones normales que la hemoglobina rica en hierro de los vertebrados, en condiciones fr\u00edas y con bajos niveles de ox\u00edgeno, el transporte de ox\u00edgeno con hemocianina es m\u00e1s eficiente que con hemoglobina. La hemocianina se disuelve en el plasma en lugar de ser transportada dentro de gl\u00f3bulos rojos, lo que le da a la sangre de los pulpos un color azulado.<\/p>\n<p><strong>\u00a0<\/strong><\/p>\n\n\n\n<div class=\"wp-block-buttons is-layout-flex wp-block-buttons-is-layout-flex\"><\/div>\n\n\n\n<div style=\"height:25px\" aria-hidden=\"true\"
