Daily Warm-up March 27th What is the cell-mediated immune system responsible for? HW: -Read 34.1, poster due tomorrow, study for quiz Turn in: -Nothing

Endocrine System Hormones: chemical messengers that travel through blood to … Target cells: have receptors on membrane for hormone Much slower than nervous system Composed of glands Good for gradual changes in body -Reproduction, growth, digestion

Simple Endocrine Pathway Endocrine cell receives stimulus and secretes a hormone Hormone travels through blood system to target cell Signal transduction within target cell produces response

Types of Hormones Steroid hormones Nonsteroid hormones -Made of lipids (cholesterol) -Can pass through cell membrane Nonsteroid hormones -Cannot pass through membrane
