Chapitre 8 : Advanced endocrine system physiology
À propos de ce chapitre
You can’t really point to any single organ as “the endocrine system,” because they’re actually a family of glands that secrete hormones into the body. Hormones travel through the bloodstream to interact with specific target cells and organs. This signaling system helps to keep the entire body well-balanced and on the same page.
Glands are special organs that secrete chemical messages called hormones, which seep into the blood - it’s like putting a tea bag in hot water. As the heart pumps, this blood carries these chemical messages throughout the body, allowing the hormones to interact with specific target cells and organs. Endocrine glands help us to maintain our appetites, grow up, metabolize molecules, concentrate urine,- and oh, so much more! We will examine how these variegated hormones play a role in homeostasis as the body responds to a changing environment.
