Document Summary

An endocrine gland is a gland of the endocrine system that secretes its products, usually hormones, directly into the blood rather than through a duct. Hormones are chemical messengers that are secreted directly into the blood, which carries them to organs and tissues of the body to exert their functions. The endocrine system includes: adrenal, hypothalamus, ovaries, pancreas, parathyroid, Homeostasis is an organism"s ability to maintain a steady state or internal balance regardless of external environment. It doesn"t mean that everything in the body is kept the same. It is a dynamic equilibrium i. e. working to get changes in temp, ph, etc. back into the correct range. In the nervous system, neurons transmit signals along dedicated routes, connecting specific locations in the body. The nervous system works hand in hand with the endocrine system to maintain homeostasis. The hypothalamus acts as the body"s thermostat because it ensures that the body temperature is constantly maintained within the optimal range.
