Verified step by step guidance

Understand the primary function of the circulatory system, which is to transport blood, nutrients, gases, and waste products throughout the body.

Consider the role of the respiratory system, which is responsible for the exchange of gases (oxygen and carbon dioxide) between the blood and the air.

Recognize that the circulatory and respiratory systems work closely together to ensure that oxygen is delivered to tissues and carbon dioxide is removed, a process known as gas exchange.

Evaluate the other systems mentioned: the digestive system aids in nutrient absorption, the skeletal system provides structure and support, and the integumentary system protects the body, but none are as directly involved in gas exchange as the respiratory system.

Conclude that the circulatory system works most closely with the respiratory system to maintain efficient gas exchange and overall homeostasis in the body.
