Glycogenesis
| Question | Answer |
|---|---|
| detects glucose | pancreas |
| stores gluclose as glycogen | liver |
| process of storing gluclose as glycogen | glycogenesis |
| polymer of glucose | glycogen |
| released when gluclose levels are too low; hormone that uses up glycogen stored in the liver | glucagon |
| process of breaking down glycogen with glucagon | glycogenolysis |
| process that uses insulin | glycogenesis |
| process that uses glucagon | glycogenolysis |
| normal body temp | 36-37.5 C |
| primary tissue that releases heat | muscle |
| response to falling body temp; two answers | shivering thermogenesis & peripherial blood flow (dialation of blood vessels) |
| allows heat to escape by dialating blood vessels | peripheral blood flow |
| body temp falls below homeostasis | hypothermia |
| two systems that act together to coordinate homeostasis in the body | endocrine and nervous |
| small structure in the brain; regulates temp involunarilly | hypothalmus |
| body's thermostat | hypothalmus |
| when the body is too cold, the hypothalmus... | sends impulses to constrict blood vessels |
| when the body is too hot, the hypothalmus... | sends impulses to dialate blood vessels |
| constrication of blood vessels | vascoconstrication |
| dialation of blood vessels | vasodialation |
| damage by vasoconstriction | frostnip, frostbite, deep frostbite |
| automatic response of the muscles to cold conditions | shivering thermogenesis |
| high temps in the body | hyperthermia |
| the lose of heat to the environment due to higher temps in the body but requiring lower temps in the environment | vasodialation |
| heat as an environmental stimulus causing the body to produce this for evaporative cooling | sweat |
| evaporative cooling will not work if these two factors are too high | humidity and temp |
| another name for heat stroke | hyperthermia |
| sweat is regulated by this involuntary system | sympathetic nervous system |
| another name for blood vessels | arterioles |
| temporary increase of temp from the hypothalamic setpoint | fever |
| a fever causes this system to work more effectively | immune system |
| the two types of sweat glands | eccrine & apocrine |
| this sweat gland is located throughout the body & functions as a temp reducer | eccrine sweat gland |
| larger sweat gland; found in groin and armpits. Does not begin to function until the onset of puberty. Linked to pheromone | apocrine sweat gland |
