blsea [12.9K]

Answer:

pulmonar; sistemica; plasma

Explanation:

La circulación pulmonar es responsable de llevar sangre del corazón a los pulmones. En este caso, la sangre rica en dióxido de carbono sale del ventrículo derecho a través de la arteria pulmonar, llega a los pulmones, sufre intercambio de gases y regresa a la aurícula izquierda del corazón a través de las venas pulmonares.

La circulación sistémica es responsable de garantizar que la sangre oxigenada se transporte por todo el cuerpo y que la sangre rica en dióxido de carbono regrese al corazón.

El plasma sanguíneo es una solución acuosa amarillenta que consiste en agua, minerales y proteínas. Su función es transportar estas sustancias por todo el cuerpo. El plasma representa aproximadamente el 55% del volumen sanguíneo.
