Circulatorio
Sistema circulatorio en el reino animal Heart Heart Hemolymph in sinuses surrounding organs Interstitial fluid Anterior vessel Small branch vessels in each organ Lateral vessel Ostia Dorsal vessel (main heart) Tubular heart An open circulatory system. Auxiliary hearts A closed circulatory system. Ventral vessels PECES ANFIBIOS REPTILES (EXCEPTO AVES) Capilares Branquia Lung and skin capillaries Arteria Branquia circulacion Pulmocutaneous circuit Heart: Ventricle (V) Atrium (A) A A MAMIFEROS Y AVES Lung capillaries Right systemic aorta Lung capillaries Pulmonary circuit A Left A systemic aorta V Left V Right Systemic Vein circulation V Left Right Systemic circuit Systemic capillaries Systemic capillaries Systemic capillaries Pulmonary circuit A A V V Right Left Systemic circuit Systemic capillaries 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.
