Study Notes
Homeostasis and Internal Environment
- Homeostasis is the ability of an organism to maintain a stable internal environment despite changes in the external environment.
- The internal environment of an organism consists of the fluid-filled space between cells, including blood plasma, lymph, and interstitial fluid.
Conditions for Efficient Cell Function and Healthy Growth
- An organism must be able to adjust to changes in temperature, pH, oxygen levels, nutrient availability, and waste removal to maintain efficient cell function and healthy growth.
Components of Homeostatic Processes
- Homeostatic processes involve three components: receptors, effectors, and negative feedback loops.
- Receptors detect changes in the internal environment and send signals to the brain or other control centers.
- Effectors, such as muscles or glands, respond to the signals and make changes to restore balance.
- Negative feedback loops regulate the response to maintain homeostasis.
Osmoregulation in Unicellular Organisms
- In unicellular organisms, osmoregulation is ensured through the cell membrane, which regulates the movement of water and ions to maintain proper osmotic balance.
