{'heart': [1, 0, 0, 0], 'tissues': [6, 0, 3, 7], 'oxygen': [3, 0, 1, 0], 'function': [11, 2, 3, 13], 'carbon dioxide': [2, 0, 5, 6], 'body': [27, 3, 23, 37], 'blood': [5, 0, 0, 1]}
The correct answer is option 4, which states that the function of the heart is to pump blood to different parts of the body. This statement accurately describes the main role of the heart. The heart is a vital organ that is responsible for circulating oxygenated blood to all parts of the body, delivering oxygen and necessary nutrients to the tissues and organs. It does not supply oxygen directly to the tissues (option 1), carry carbon dioxide (option 2), or throw away waste materials (option 3). It is important to note that while the heart plays a crucial role in the circulatory system, other organs such as the lungs are responsible for oxygenating the blood and removing waste products like carbon dioxide.
