circuitos sistémicos incluyen todos los tejidos del cuerpo excepto los pulmones. Tenga en cuenta
que los sistemas circulatorio aparecen como si el animal está frente a usted: con el lado derecho
del corazón se muestra a la izquierda y viceversa.
Systemic circuits include all body tissues except lungs. Note that circulatory systems are depicted as if the
animal is facing you: with the right side of the heart shown at the left and vice-versa.
