The homeostatic regulation of an animal requires three basic components,…………. to detect changes, ........... to evaluate the changes and ............... to adjust the changes respectively. A. Receptor, affectors, effectors B. Brain, spinal cord, effectors C. Receptors, integrators, effectors D. Receptors, integrator, effectors
Hint: To detect changes is called receiving signals. Evaluation of the external changes is what integrates the internal system to the external environment. To adjust the changes accordingly, we have to respond to the signals received.
Complete answer: Homeostasis is a kind of regulation in which our organ systems or internal environment is maintained by acclimatizing with the changes of the external environment. For this to occur, three basic components are required: receptors to receive or perceive the signals or stimuli from the external; integrators that perform the main activity of acclimatization by procuring adjustments in metabolic activities. The result is put out by the motor organs known as the effectors.
Additional information: Steps in maintaining homeostasis: 1. Temperature: The body must maintain a constant temperature. 2. Glucose: The body must regulate glucose levels to stay healthy and fit. 3. Toxins: Toxins in the blood can disturb the body's homeostasis. 4. Blood Pressure: The body must maintain appropriate levels of blood pressure. 5. pH.
So, the correct option is C. Receptors, integrators, effectors
Note: Homeostasis can occur even in smaller regions such as within a secretory pathway or an organ. It is basically the tendency to resist any change and hence it generally involves negative feedback mechanisms.
