The left atrium transfers oxygenated blood to the left ventricle,not the right ventricle. Thus,statement $(iii)$ is false.$4$. The right atrium receives deoxygenated blood from the body,and the left ventricle pumps oxygenated blood to the body. Thus,statement $(iv)$ is true.Therefore,statements $(ii)$ and $(iv)$ are correct.
