What is the primary role of the circulatory system in animals?
Correct Answer: The primary role of the circulatory system is to transport nutrients, gases, hormones, and waste products throughout the body.
Step 1: Understand that the circulatory system is like a delivery service for the body.
Step 2: Know that it moves important things like nutrients (food), gases (like oxygen and carbon dioxide), hormones (chemical messengers), and waste products (things the body doesn't need anymore).
Step 3: Realize that this system helps keep all parts of the body healthy and working properly by delivering what they need and taking away what they don't.
