To answer you must fill in the free spaces or choose the correct answer according to the type of question. you can see this animation: the two auricles contract simultaneously, forcing the blood to pass through the auricles are emptied and filled. ventricular systolethe ventricles contract and emptying. the atrioventricular valves are closed / opened. blood is forced to pass into the artery and the artery the semilunar valves of the arteries are closed / open. simultaneously blood begins to flow into the relaxed atria.diastole atrial and ventricularthe blood enters the auricles for if initially the atrioventricular valves are closed, they immediately open. because the ventricles are relaxed, the blood tends to retreat from the aorta and pulmonary artery causing the closure of the valves c) the heart cycle of a person, under normal conditions, has an approximate duration of 0.8 seconds.- how long does the general diastole last? - and the atrial systole? - and the ventricular systole? in spanishel ciclo cardiacopara responder debe rellenar los espacios libres o escoger la respuesta correcta según el tipo de pregunta. puede visionar esta animación: sÃstole auricularlas dos aurÃculas se contraen simultáneamente, forzando la sangre a pasar dentro las aurÃculas se vacÃan y se llenan. sÃstole ventricularlos ventrÃculos se contraen y se vacÃan. las válvulas auriculoventriculares se cierran / abren. la sangre es forzada a pasar hacia la arteria y la arteria las válvulas semilunares de las arterias se cierran / abren. simultáneamente la sangre comienza a fluir dentro de las aurÃculas relajadas.diástole auricular y ventricularla sangre entra en las aurÃculas por las si inicialmente las válvulas auriculoventriculares están cerradas, enseguida se abren. como los ventrÃculos están relajados, la sangre tiene tendencia a retroceder desde la arteria aorta y pulmonar provocando el cierre de las válvulas c) el ciclo cardÃaco de una persona, en condiciones normales, tiene una duración aproximada de 0,8 segundos.- ¿qué duración tiene la diástole general? - y la sÃstole auricular? - y la sÃstole ventricular?
