A

nervous, sensory, endocrine

175
Q

organ system that provides support and movement

A

musculoskeletal

176
Q

organ systems that are involved in regulation and maintenance like maintaining the body’s chemistry

A

digestive, circulatory, respiratory, urinary systems

177
Q

organ systems that deal with bodily defense

A

integumentary and immune

178
Q

organ system that is involved in reproduction and development and nurtures the developing embryo and fetus as well as the continuance of genes

A

reproductive system

179
Q

the dynamic constancy of the internal environment is called

A

homeostasis

180
Q

two things that need to remain relatively constant in the body

A

water in cells, temperature

181
Q

the body uses these mechanisms to maintain homeostasis

A

negative feedback

182
Q

6 steps of negative feedback

A

stimulus, sensors, integrating center, effector, response, sensor reset

183
Q

negative feedback loops often oppose each other to produce finer degree of control called blank

A

antagonistic effectors

184
Q

This type of feedback does not maintain homeostasis

A

positive

185
Q

examples of positive feedback in body

A

clotting and contraction of uterus during childbirth

186
Q

the rate of any chemical reaction is affected by blank

A

temperature

187
Q

three things that determine body temperature

A

behavior, metabolism, environment

188
Q

Four mechanisms of heat transfer

A

radiation, conduction, convection, evaporation

189
Q

mechanism of heat transfer that deals with electromagnetivity

A

radiation

190
Q

mechanism of heat transfer that is directly between two objects

A

conduction

191
Q

mechanism of heat transfer that is by the movement of a gas or liquid

A

convection

192
Q

mechanism of heat transfer that is the conversion of water to gas

A

evaporation

193
Q

Three classes of organisms that generate heat in different ways

A

endotherms, ectotherms, heterotherms

194
Q

organism that use metabolism to generate body heat and maintain temperature above ambient temperature

A

endotherms

195
Q

these organisms produce no heat so they have low metabolic rates

A

ectotherms

196
Q

ectotherms regulate temperature using blank

A

behavior

197
Q

heat exchange that ectotherm marine animals use to limit heat loss in cold water

A

countercurrent blood flow

198
Q

warm blood is pumped from within the body in arteries warms the cooler blood returning from the skin within veins… this is called

A

countercurrent heat exchange

199
Q

how endotherms cool themselves down

A

panting or sweating

200
Q

this increases blood flow which increases heat dissipation

A

vasodilation
