{'circulatory system': [1, 0, 1, 0], 'aorta': [4, 0, 3, 0], 'right atrium': [0, 0, 1, 0], 'left atrium': [0, 0, 1, 0], 'right ventricle': [0, 0, 2, 1], 'left ventricle': [0, 0, 8, 0], 'blood': [5, 0, 0, 1], 'human body': [40, 2, 44, 29]}

The correct answer is option 2: Left ventricle.

The human circulatory system is responsible for delivering oxygen and nutrients to the body`s tissues and removing waste products. The aorta is the largest artery in the body and carries oxygenated blood from the heart to the rest of the body.

To understand why option 2 is the correct answer, let`s briefly review the flow of blood through the heart. Blood enters the heart through the right atrium from the body`s tissues. It then flows into the right ventricle, which pumps it to the lungs for oxygenation. Oxygenated blood then returns to the heart and enters the left atrium. From the left atrium, blood passes into the left ventricle.

The left ventricle has the thickest muscular wall among all the heart chambers. This is because it is responsible for pumping oxygenated blood out of the heart and into the aorta, which will distribute the blood to the rest of the body. Therefore, the blood enters the aorta from the left ventricle.
