After completing chapter 34, you will be able to: Describe the organs of the alimentary canal and their functions; explain the functions of the digestive system’s accessory organs; identify the nutrients absorbed by the digestive system and where they are absorbed; describe the causes, signs and symptoms, and treatments of various common diseases and disorders of the digestive system. | 34 The Endocrine System Learning Outcomes (cont.) Describe the general functions of hormones and the endocrine system. Identify the hormones released by the pituitary gland, thyroid gland, parathyroid glands, adrenal glands, pancreas, and other hormone-producing organs, and give the functions of each. Learning Outcomes (cont.) Explain the effect of stressors on the body. Describe the causes, signs and symptoms, and treatments of various endocrine disorders. target tissues Introduction The endocrine system includes the organs that secrete hormones Hormones Regulate chemical reactions in cells Control functions of the organs, tissues, and other cells Glands secrete hormones into bloodstream to Learning Outcome: Describe the general functions of hormones and the endocrine system. The endocrine system includes the organs of the body that secrete hormones directly into body fluids such as blood.

The endocrine system includes the organs of the body that secrete hormones directly into body fluids such as blood. This chapter discusses the processes and organs of the endocrine system. In addition to the glands The heart and kidney both secrete a hormone (not a primary function) The GI tract also secretes hormones (not a primary function) Hormones Endocrine glands Ductless Release hormones Directly into target tissues Into bloodstream to be carried to target tissues Hormones – chemicals secreted by a cell that affect the functions of other cells Learning Outcome: Describe the general functions of hormones and the endocrine system. Hormones The target cells are the cells that contain the receptors for the hormone. A hormone cannot affect a cell unless the cell has receptors for it. Refer to TABLE 34-1 Endocrine Glands: Their Hormones and Actions. Types of Hormones Steroidal Hormones Cross cell membrane Bind to receptor in cell nucleus Hormone-receptor complexes Turn a gene on or off Enable cell to carry out functions Learning Outcome: Describe the general functions of hormones and the endocrine system. Many hormones in the body are
