(A) $(1)$ In fish,the heart pumps deoxygenated blood to the gills for oxygenation,which then passes directly to the body tissues. This is known as single circulation.In amphibians,the heart has two atria and one ventricle. The oxygenated and deoxygenated blood mix in the ventricle before being pumped out,which is known as incomplete double circulation.$(2)$ The tricuspid valve is located between the right atrium and the right ventricle to prevent backflow of blood.The bicuspid valve (also known as the mitral valve) is located between the left atrium and the left ventricle to prevent backflow of blood.
