messengers. They regulate and integrate body functions. ENDOCRINE SYSTEM The endocrine system refers to the collection of glands of an organism that secrete hormones directly into the circulatory system to be carried towards distant target organs. It is a system that controls body functions such as sleep, sexual behavior, digestion, metabolism, and physical development. The endocrine system is an information signal system like the nervous system, yet its effects and mechanism are classifiably different

Unit 1. Case Study 1. Tell Me About Blood 1. What is the significance of a lower-than-normal hematocrit? What is the effect of a bacterial infection on the hematocrit? (PAGE 618 619) First, hematocrit (HCT) is the percentage of blood made up of red blood cells. Usually measured by centrifuging a blood sample in a graduated tube and then reading the volume of red blood cells and dividing it by the total volume of blood in a sample. A significant drop in hematocrit is an indication of anemia
