Autonomic function

Japanese: 自律機能 - じりつきのう（英語表記）autonomic function

Autonomic functions are also called vegetative functions or involuntary functions, and refer to the most basic functions of living organisms, such as circulation, respiration, digestion, excretion, metabolism, secretion, body temperature, and reproduction. Autonomic functions are primarily regulated by the autonomic nervous system and hormones to constantly maintain the internal environment of the body in an optimal state for sustaining life, but they can also be regulated in part by the motor nervous system. In addition to regulation by nerves and hormones, autonomic functions can also be automatically regulated by the state of the organs themselves involved in the autonomic functions, such as when an increase in blood flow to the heart increases its activity.

Japanese:

自律機能は，植物性機能あるいは不随意機能と呼ばれ，生体にとって最も基本的な，循環，呼吸，消化，排出，代謝，分泌，体温，生殖などの諸機能のことをいう。自律機能は，生体内の内部環境を常時，生命の維持に最適な状態に保つように主として自律神経系とホルモンによって調節されているが，一部運動神経系によっても調節されうる。また，神経とホルモンの調節以外にも，たとえば心臓に血液が増えると心臓の働きが亢進するように，自律機能に関与する諸器官そのものの状態によっても自動的に調節される場合もある。
