Which system consists of the heart and arteries?

Respiratory system
Endocrine system
Circulatory system
Nervous system

The correct answer is: Circulatory system

The circulatory system, also known as the cardiovascular system, is the correct answer because it is the biological system in the body responsible for the movement of blood, nutrients, gases, and wastes to and from cells. It includes the heart, a muscular organ that pumps blood throughout the body, and the arteries, which are the blood vessels that carry blood away from the heart to various tissues and organs. The circulatory system is vital for maintaining homeostasis and ensuring that all body parts receive the oxygen and nutrients they need while also removing waste products. Understanding the circulatory system is fundamental in the context of barbering, especially when considering the importance of a healthy circulatory system for overall skin health and the effectiveness of services like shaving and skin care treatments. Other systems mentioned do not consist of the heart and arteries; for instance, the respiratory system is focused on gas exchange, while the endocrine system deals with hormones and the nervous system involves signaling throughout the body.
