Briefly describe the regulatory functions of the endocrine system: metabolism (regulates rate of chemical changes in tissues, control of food intake & digestion, tissue development. Immune system regulation (controls the production and functions of immune cells) Describe each of the different functional classifications of chemical messengers. These prostaglandins trigger uterine cramps to help expel the endometrium. Fat based hormones are *non polar*, dissolve in fats and are usually formed by cholesterol. Bpk105 midterm review: can pass through target cell membranes to reach *receptors within the cell* which then travel to the nucleus, binding to dna for transcription, turning on or off a portion of it. If there are no binding protein, then the hormone would diffuse quickly and be eliminated by enzymes: ex: *gonadal hormones* such as estrogen and testosterone which are produces by the ovaries and testis, regulating reproductive functions; *cholesterol* Describe the concept of receptor site specificity using any two hormones as an example.
