Two systems that detect changes in the internal environment are the nervous system and the endocrine system. The nervous system uses sensory receptors to detect changes in stimuli such as temperature or pressure, while the endocrine system monitors chemical signals in the blood to maintain balance within the body. Both systems work together to regulate physiological responses and maintain homeostasis.

Why diphenylamine is called internal indicator?
Diphenylamine is considered an internal indicator because it changes color in the presence of nitrates by forming a blue complex. This color change is used to detect the presence of nitrates in solutions without the need for an external indicator.
What are the sensory receptors called that detect change?
The sensory receptors that detect change are called mechanoreceptors. These receptors are sensitive to mechanical stimuli such as pressure, vibration, and stretch, allowing the body to detect changes in its environment. Examples of mechanoreceptors include Pacinian corpuscles and Merkel cells.
How does the body detect heat?
Our bodies have nerve cells called thermoreceptors that measure temperature of our internal body and the external environment. When these nerve cells are stimulated by changes inside our bodies and in the world outside, they send their information to the brain, where it is mostly the job of the medulla oblongata to make changes to keep our internal body temperature constant.
Cells that detect conditions in the body's environment?
white blood cells
What are the limits on are ability to sense stimuli in your environemt?
Our ability to sense stimuli in our environment is limited by the range of frequencies and intensities that our senses can detect. Additionally, our perception can be influenced by factors like attention, expectation, and individual differences. Lastly, our sensory systems can become desensitized or fatigued over time, affecting our ability to detect stimuli.
What 2 systems control homeostasis?
The two systems that control homeostasis in the body are the nervous system and the endocrine system. The nervous system helps to detect changes in the internal and external environment, while the endocrine system releases hormones to regulate and maintain a stable internal environment.
A structure that senses change is called?
A sensor. Sensors are devices or systems that detect changes in their environment and convert them into electrical signals or other forms of output for monitoring or control purposes.
What is the ability to detect physical energy through your visual or touch systems is known as?
The ability to detect physical energy through your visual or touch systems is known as sensory perception. This involves interpreting information from the environment through sensory organs such as the eyes and skin.
Which represent the correct order of homeostatic control system?
The correct order of a homeostatic control system is: Stimulus - a change occurs in the internal or external environment. Receptor - sensors detect the change in the environment. Control center - processes the information and determines the appropriate response. Effector - carries out the necessary response to restore homeostasis.
Neurons with the ability to monitor the environment are called what?
Sensory neurons are the type of neurons that have the ability to monitor the environment. They are specialized to detect stimuli from the external or internal environment and transmit this information to the brain for processing.
What is a way that a sensor can be used in a car?
Various ways. Infra Red sensors can be used for alarm systems to detect doors being opened or motion inside the vehicle. Sensors can be used in doors to detect when the door is opened, and trigger the internal light.
Does a receptor detect change in the environment?
Yes, receptors are specialized cells or proteins that detect changes in the environment or within the body, such as changes in temperature, pressure, or the presence of chemicals. They transmit this information to the nervous system for further processing and response.
What is the instrument used to detect a change in atmosphere pressure which usually signals a change in weather QUICK I NEED the answer sooon?
A barometer is used to detect changes in atmospheric pressure, which can signal a change in weather. It measures the pressure exerted by the atmosphere and can provide an indication of incoming weather systems.
What is stimulus with examples?
A stimulus is a DETECTECTABLE change in the environment. e.g. light is a stimulus to an animal or plant if it can detect the light with a sensing eye or chemical
Detect changes of internal or external stimulus?
sensory receptors
What does PIR detect?
detect any changes in the environment (noise level, vibration, temperature)
