A student argues that the cardiovascular system and circulatory system are the same. Using the provided descriptions, which statement best evaluates this claim?
They are the same because both involve the heart and blood vessels moving blood, nutrients, and wastes.
They differ because the cardiovascular system focuses only on lungs and airways, while the circulatory system handles hormones.
They are different because the circulatory system provides structural support and mineral storage, while the cardiovascular system pumps blood.
They are the same because both process food into absorbable nutrients for energy and growth.
