  23. pituitary gland- secretes hormones that influence the function of several other glands & tissues. (controls other glands.)
    master gland
  24. existence and maintenance of a relatively constant environment within the body despite fluctuations in either the external and internal environment
    homeostasis
  25. tissue on which a hormone acts
    target tissue
  26. chemical messengers, secreted by endocrine glands into blood that acts on a target tissue to produce a specific response
    hormone
  27. gland that secretes to a surface or outward through a duct
    exocrine gland
  28. gland that secretes (hormones, etc) internally
