  • Ductless because the hormones are secreted directly into the blood stream. Hormones are circulated throughout the whole body but only have an influence on specific cells, tissues, and organs. Exocrine- sweat, salivary, lacrimal, and pancreas
  • Master gland because it major influences on the body’s activities. Connected to the hypothalamus Has anterior and posterior lobe
  • Anterior lobe growth hormone (GH) or somatotropin prolactin hormone (PRL) thyroid stimulating hormone (TSH) adrenocorticotropic hormone (ACTH) follicle stimulating hormone (FSH) luteinizing hormone (LH) Posterior Lobe vasopressin oxytocin
  • It lies on either side of the larynx over the trachea About 2 inches long with two lobes joined by strands of thyroid tissue called the isthmus Secretes 3 hormones thyroxine (T4) triiodothyronine (T3) calcitonin
  • Secretes parathormone
  • Located in the scrotum
  • Located in the pelvic cavity
