Answer #1

Frog heart consist of three chambers viz, one ventricle and two atria. Atrium collect deoxygenated blood from veins. Blood leaves heart from ventricular side via truncus arteriosus. This blood enters ventricular as well as in pulmonary circulation.

  • The walls of ventricles are thicker as they have to pump blood to upside against the gravity towards brain and other vital parts.
  • This part is more muscular.
  • Atrium have comparatively low resistance towards flow of blood, and, hence they require less musculature.
