Verified step by step guidance1
Step 1: Begin by identifying the primary function of the heart. The heart is responsible for pumping blood throughout the body, delivering oxygen and nutrients to tissues, and removing waste products.
Step 2: Understand the organ systems listed in the options. The circulatory system is responsible for transporting blood, oxygen, and nutrients. The nervous system controls and coordinates body activities. The respiratory system facilitates gas exchange (oxygen and carbon dioxide). The digestive system processes food and absorbs nutrients.
Step 3: Match the function of the heart to the correct organ system. Since the heart pumps blood, it is directly involved in the circulatory system, which includes the heart, blood vessels, and blood.
Step 4: Eliminate the other options by considering their primary functions. The nervous system does not involve blood transport, the respiratory system focuses on breathing and gas exchange, and the digestive system is responsible for food processing.
Step 5: Conclude that the heart belongs to the circulatory system based on its role in blood circulation and nutrient transport.
