Question

What is the term used for secretions of endocrine glands responsible for changes taking place in the body?

Answer 1

Hormones are chemical substances that are secreted by endocrine glands. They are responsible for changes taking place in the body. The endocrine system is made up of the endocrine glands that secrete hormones. Some glands also have non-endocrine regions that have functions other than hormone secretion. For example, the pancreas has a major exocrine portion that secretes digestive enzymes and an endocrine portion that secretes hormones. The ovaries and testes secrete hormones and also produce ova and sperm. Some organs, such as the stomach, intestines, and heart, produce hormones, but their primary function is not hormone secretion.
