Final answer:
The endocrine system uses hormones as its communication chemicals, which are secreted into the blood by endocrine glands and control various body functions to maintain homeostasis.
Step-by-step explanation:
The endocrine system is made up of a network of glands that use hormones as the communication chemicals to carry its messages. These hormones are secreted into the bloodstream by ductless glands known as endocrine glands and travel throughout the body, affecting any cells that contain receptors for them. This system plays a crucial role in maintaining the body's homeostasis by controlling various functions, including metabolism, growth, and sexual development, through slow but long-lasting chemical signaling.
Examples of Endocrine Glands:
The pituitary gland, which is the master gland, controlling other endocrine glands.
The pancreas, which produces insulin and glucagon that regulate blood sugar levels.
The thyroid gland, which secretes hormones regulating metabolism.
The adrenal glands, which produce stress response hormones like epinephrine and norepinephrine.
