2. Human Body SystemsSection 351 This section describes human organ systems and explains how the body maintains homeostasis. 3. Organization of the Body List the levels of organization in amulticellular organism, fromsmallest to largest. Cells Tissues Organs Organ systems 4. Coordinates the bodys response to changes in itsNervous system internal and external environmentsStores mineral reserves and provides a site forSkeletal system blood cell formationIntegumentary system Serves as a barrier against infection and injuryEndocrine systemEliminates wastes and maintains homeostasisLymphatic/ImmunesystemsHelps protect body from disease. Helps produce voluntary movement, circulateMuscular systemblood, and move foodReproductivesystem Produces reproductive cellsRespiratory system Provides oxygen and removes carbon dioxideExcretory system Eliminates wastes and maintains homeostasis Brings materials to cells, fights infection, and helpsCirculatory systemto regulate body temperatureDigestive system Converts food so it can be used by cells 5. Organization of the Body What are four types of tissues foundin the human body The four types of tissues are muscle tissue, epithelial tissue, connective tissue, nervous tissue 6. Organization of the Body The eye is an example of a (an) ____.organ 7. Organization of the Body Circle the letter of the type of tissue that covers interior and exterior body surfaces. epithelial 8. Organization of the BodyWhat is a gland? A gland is a structure that makesand secretes a particular productsuch as saliva, sweat, or milk. 9. Organization of the Body Circle the letter of the type of tissuethat connects body parts. connective 10. Maintaining Homeostasis The process of maintaining acontrolled, stable internalenvironment is called homeostasis 11. Maintaining Homeostasis The process in which a stimulusproduces a response that opposesthe original stimulus is referred toas________. feedback inhibition 12. Maintaining Homeostasis Fill in the missing labels in the diagram to show how a thermostat uses feedback inhibition to maintain a stable temperature in a house. 13. Maintaining Homeostasis Is the following sentence true orfalse? The part of the brain that monitorsand controls body temperature is thehypothalamus. true 14. Maintaining Homeostasis What happens if nerve cells sensethat the core body temperature hasdropped below 37C? The hypothalamus produceschemicals that signal cellsthroughout the body to speed uptheir activities, which causes agradual rise in body temperature. 15. Maintaining Homeostasis What happens if the bodytemperature rises too far above37C? The hypothalamus slows downcellular activities, minimizing theproduction of heat.
