Five environmental requirements to maintain life:
water, food, heat, pressure, oxygen
what is homeostasis
the condition of a stable internal environment
the body maintains homeostasis through a number of self-regulating control systems that share what three components
receptors, set point, effectors
provide information about specific conditions in the internal environment
receptors
tells what a particular value should be, such as body temperature
set point
bring about responses that alter conditions in the internal environment
effectors
If the receptor measures deviations from the set point, effectors are activated that can return conditions toward normal. As conditions return toward normal, the deviation from the set point progressively lessens and the effectors are gradually shut down.
negative feedback mechanism
Examples of a negative feedback mechanism:
A room has a furnace and air conditioner. If the room temperature is to remain near 20 C (68 F), the thermostat is adjusted to an operating level, or set point of 20 C. A thermostat, which senses temperature changed, signals the furnace to start and the air conditioner to stop whenever the room temperature drops below the set point. If the temperature rises above the set point, the thermostat stops the furnace and starts the air conditioner. As a result, the room maintains a relatively constant temperature.
Body temperature is also regulated in this way. The “thermostat” is in the brain, and if the temperature of the body reaches too high or drops too low, the brain signals and measures are taken (like shivering or sweating) for the body temperature to return to normal.
A process that moves conditions away from the normal state
positive feedback mechanism
Two examples of positive feedback mechanisms:
In blood clotting, the chemicals that carry out clotting stimulate more clotting, minimizing bleeding.
Another positive feedback mechanism increases the strength of the uterine contractions during childbirth, helping to bring the new individual into the world.
What kind of conditions do positive feedback mechanisms produce?
unstable
hormone produced by pituitary glands that stimulates uterine contractions

steps to maintain body temp at 98.6 if it falls below
below: person is exposed to cold and temp begins to drop, the temp receptors sense this change and the temp control center triggers heat-generating and heat conserving activities, muscles are stimulated to contract involuntarily, called shivering. this contraction produces heat, which helps warm the body. at the same time, blood vessels in the skin are signaled to constrict so that less war blood flows through them, in this way, deeper tissues retain heat that might otherwise be lost
steps to maintain body temp at 98.6 if it falls above
above: person is overheated, brain’s temp control center triggers a series of changes that promote loss of body heat. sweat glands in the skin secrete perspiration, and as this fluid evaporates from the surface, heat is carried away and skin is cooled. at the same time, the brain center dilates blood vessels in the skin. this action allows more blood carrying heat from deeper tissues to reach the surface where the heat is lost to the outside, the brain stimulates an increase in heart rate, which sens a greater volume of blood into surface vessels, and an increase in breathing rate, which allows the lungs to expel more heat-carrying air
