Human (mammalian) Body Systems
Begin your tour of body systems by reviewing Figure 35.2 on page 892-893.
Remember that all of your body systems are integrated and regulated by the neuroendocrine
system (the coordination of the nervous and endocrine (hormones) systems. As time is
limited, focus on the figures indicated.
Digestive System Chapter 38-2 Figure 38.10, p 979
* components (primary organs, accessory organs/glands)
* absorptive structures of the intestines (capillary interface) ... villi
* peristalsis, sphincters
Endocrine system Chapter 39 Figure 39.2, p 998
* definition of hormone
** types of hormones (chemical classes)
* the connection to the brain/nervous system ... the hypothalamus

Circulatory System (cardiovascular) Chapter 37-1, 37-2
** three main functions (transport, thermoregulation, immunity)
** components of blood and their functions (RBC’s, WBC’c, platelets, plasma)
* vessel types ... veins, arteries, capillaries
* blood types ... inheritance; antigen/antibodies; transfusion compatibility
