Step 1: Understand circulatory systems.
In humans, blood circulation is divided into two main types: systemic circulation and pulmonary circulation.
Step 2: Define systemic circulation.
Systemic circulation carries oxygenated blood from the heart (left ventricle) to all body tissues and returns deoxygenated blood back to the heart.
Step 3: Define pulmonary circulation.
Pulmonary circulation carries deoxygenated blood from the heart to the lungs and returns oxygenated blood back to the heart.
Step 4: Evaluate option (2).
Systemic circulation is correctly associated with oxygenated blood delivery to body tissues. Hence, this is correct.
Step 5: Evaluate other options.
Pulmonary circulation is not "greater circulation" (so 1 is incorrect). It does not carry only oxygenated blood (so 3 is incorrect). Systemic circulation is not deoxygenated blood (so 4 is incorrect).
Step 6: Final conclusion.
Therefore, only option (2) is correctly matched.
