Which of the following statements is/are correct ? 1. Coronary artery supplies blood to heart muscles. 2. Pulmonary vein supplies blood to lungs. 3. Hepatic art^y supplies blood to kidneys. 4. Renal vein supplies blood to kidneys. Select the correct answer using the code given below:

Statement 1 is correct as coronary arteries branch from the aorta to supply oxygen-rich blood specifically to the heart muscle. Statement 2 is technically correct in the context of pulmonary circulation, where pulmonary veins carry oxygenated blood from the lungs back to the heart's left atrium. Statement 3 is incorrect because the hepatic artery supplies oxygenated blood to the liver, not the kidneys. Statement 4 is incorrect because the renal vein drains deoxygenated blood away from the kidneys toward the heart; it is the renal artery that supplies blood to the kidneys. Therefore, only statements 1 and 2 are accurate descriptions of blood supply and transport directions in the human cardiovascular system. Arteries generally carry blood away from the heart to organs, while veins return blood to the heart.
