3 Hemolymph in sinuses surrounding organs Heart Anterior vessel Ostia Tubular heart An open circulatory system. Lateral vessel A closed circulatory system. Auxiliary hearts Ventral vessels Dorsal vessel (main heart) Small branch vessels in each organ Interstitial fluid Heart

4 PECES Capilares Branquia ANFIBIOS Lung and skin capillaries REPTILES (EXCEPTO AVES) Lung capillaries MAMIFEROS Y AVES Lung capillaries Branquia circulacion Heart: Ventricle (V) Atrium (A) Arteria Vena Circulación sistémica Systemic capillaries Systemic circuit Pulmocutaneous circuit Right Left A A V A V A V Systemic capillaries Right Left Pulmonary circuit Right systemic aorta V A V Systemic capillaries RightLeft Pulmonary circuit A Systemic circuit Left systemic aorta 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.
