What does the circulatory system consist of?

Cleaning
Charge nurse
Circulatory system
Chronic

The correct answer is: Circulatory system

The circulatory system is primarily composed of the heart, blood vessels, and blood. Its main function is to transport nutrients, gases (like oxygen and carbon dioxide), hormones, and waste products throughout the body. This system plays a crucial role in maintaining homeostasis, facilitating the exchange of substances with cells, and supporting the immune system by transporting white blood cells and antibodies. The other choices—cleaning, charge nurse, and chronic—do not pertain to the components or functions of the circulatory system. They represent concepts related to other topics in healthcare and nursing, but none describe the anatomical structures or functions of the circulatory system. Understanding the specific makeup and purpose of the circulatory system is essential for a CNA, as it informs how to monitor and support a patient’s overall health.
