autoregulation

Thân thiện

The body uses autoregulation to keep blood pressure stable.

Definition

Noun: 1. A biological process within a cell or organism that maintains a stable internal state: Autoregulation refers to the intrinsic ability of a biological system to adjust its function or activity to maintain a relatively constant condition, without external control.

Usage

Autoregulation is a specific term used primarily in physiology and biology. It describes self-correcting mechanisms. * The autoregulation of blood flow ensures that organs receive a constant supply despite changes in blood pressure. * A key example of cellular autoregulation is the feedback loop that controls gene expression.

Advanced Usage

• "to be under autoregulation": to be controlled or maintained by such an internal process.
  • Renal blood flow is under precise autoregulation to support kidney function.
• "the autoregulation of": used to specify the particular physiological parameter being regulated.
  • Scientists are studying the molecular basis for the autoregulation of cerebral perfusion.

Variants and Related Words

• Autoregulate (verb): To maintain a constant state through internal adjustment.
  • Some blood vessels can autoregulate their diameter.
• Autoregulatory (adjective): Of or relating to autoregulation.
  • The autoregulatory mechanism was impaired in the experiment.

Synonyms

• Homeostasis: (n.) The general tendency of an organism to maintain internal stability.
• Self-regulation: (n.) The general ability to control oneself or itself without external influence.

Related Phrases

• Feedback loop: (n.) A circular process where the output of a system influences its own operation, which is the fundamental mechanism for most autoregulation.
  • Negative feedback loops are essential for physiological autoregulation.
