The endocrine system includes the organs of the body that secrete hormones directly into body fluids such as blood. Hormones help to regulate the chemical reactions within cells. They therefore control the functions of the organs, tissues, and other cells that comprise these cells. Chapter 30 - The endocrine system. In this chapter you will learn about the processes and organs of the endocrine system. | 30 The Endocrine System 30- Learning Outcomes Define the term endocrine glands. Describe the general functions of the endocrine system. Define the term hormone. Explain the difference in hormone control by positive and negative feedback loops. 30- Learning Outcomes (cont.) Describe the locations of the hypothalamus, pituitary gland, pineal body, thyroid gland, parathyroid glands, adrenal glands, pancreas, thymus, and gonads. List the hormones released by the pituitary gland and give the functions of each. List the hormones released by the thyroid gland and parathyroid glands and give the functions of each. 30- Learning Outcomes (cont.) List the hormones released by the adrenal glands and give the functions of each. List the names of the endocrine cells of the pancreas, the hormones released by them, and the function of each hormone. List the hormones released by the pineal body, thymus, and gonads, and give the | 30 The Endocrine System 30- Learning Outcomes Define the term endocrine glands.

Many are derived from steroids that easily cross the cell membrane Examples of steroidal hormones .
