The collection of endocrine glands makes up the endocrine system. The main endocrine glands are the pituitary (anterior and posterior lobes), thyroid, parathyroid, adrenal (cortex and medulla), pancreas and gonads. The pituitary gland is attached to the hypothalamus of the lower forebrain.
Unlike exocrine glands(sweat, salivary), endocrine glands secrete their respective substances directly into the bloodstream rather than through a duct. These endocrine glands belong to the body’s control system and they produce hormones which help to regulate the functions of cells and tissues.
The network of hormone-producing organs and glands, the endocrine system, helps control body functions. The hypothalamus reacts by enhancing the appropriate endocrine activity to restore this balance.
The endocrine system works together with the nervous system to coordinate body functions and maintain homeostasis. Endocrine glands release chemicals called hormones into the bloodstream.
This lesson plan covers a 10th grade science class on the endocrine system. The objectives are for students to identify endocrine glands and their functions, match glands to functions, and understand the importance of communication in the endocrine system.
