Which body system consists of various glands located throughout the body?

Cardiovascular system
Endocrine system
Nervous system
Digestive system

The correct answer is: Endocrine system

The body system that consists of various glands located throughout the body is the endocrine system. This system is primarily responsible for hormone production and regulation, which play critical roles in various bodily functions, including metabolism, growth and development, tissue function, and mood regulation. The glands associated with the endocrine system include the pituitary, thyroid, adrenal glands, and others, which secrete hormones directly into the bloodstream to reach target organs and tissues, orchestrating complex biological processes. In contrast, the cardiovascular system focuses on transporting blood, nutrients, oxygen, and hormones throughout the body, relying on the heart and blood vessels rather than glands. The nervous system coordinates the body’s response to internal and external stimuli through neural signals, while the digestive system involves the breakdown of food and absorption of nutrients, utilizing organs such as the stomach and intestines rather than glands for its primary functions.
