Endocrine System Chapter 45 Overview: The Body?s Long-Distance Regulators Animal hormones are chemical signals that are secreted into the circulatory system and communicate regulatory messages within the body Hormones reach all parts of the body, but only target cells are equipped to respond Send chemicals around the body Specific to target cells 2 LE 45-2a Target effectors Response Simple endocrine pathway Glycogen breakdown, glucose release into blood Liver Blood vessel Pancreas secretes glucagon ( ) Endocrine cell Low blood glucose Receptor protein Stimulus Pathway Example Released compounds will elicit a response Ex: pancreas releasing glucagon with low blood sugar 3 LE 45-2b Target effectors Response Simple neurohormone pathway Stimulus Pathway Example Suckling Milk release
