×The human body has
automatic control systemsthat maintain optimal conditions for enzyme action throughout the body, as well as all cell functions. These systems may involve nervous responses (nervous system) or chemical responses (endocrine system). Examples of automatic control systems in the human body include:
- Receptors that detect a stimulus, which is a change in the environment, such as temperature change.
- Coordination centres in the brain, spinal cord and pancreas.
- Reflex actions that are automatic and rapid, such as the response of the pupil in the eyes to bright light, and the knee jerk reaction.
- Control of blood glucose concentration, body temperature, and water levels.
,The
body control systems are all automatic, and involve both nervous (nervous system) and chemical (endocrine system) responses. It has many important parts, including: Receptors detect a stimulus, which is a change in the environment, such as temperature change. Coordination centres in the brain, spinal cord and pancreas.
The human body has automatic control systems, which may involve nervous responses or chemical responses coordinated by hormones. Reflex actions are automatic and rapid. Examples include the response of the pupil in the eyes to bright light, and the knee jerk reaction. Knowledge of the reflex arc is not required.
Homeostasis maintains optimal conditions for enzyme action throughout the body, as well as all cell functions. In the human body, these include the control of: blood glucose concentration body temperature water levels These automatic control systems may involve nervous responses (nervous system) or chemical responses (endocrine system).
