Homeostasis is the process by which biological systems maintain stability while adjusting to changing external conditions. It is crucial for the proper functioning of organisms, ensuring that internal environments remain consistent and balanced.
congrats on reading the definition of homeostasis. now let's actually learn it.
Homeostasis involves multiple physiological processes such as temperature regulation, pH balance, and glucose levels.
The digestive system plays a key role in maintaining homeostasis by regulating nutrient absorption and waste elimination.
Endocrine glands release hormones that help regulate homeostatic functions like metabolism, stress responses, and fluid balance.
Imbalances in homeostasis can lead to conditions such as diabetes, dehydration, or electrolyte imbalances.
Nurses must monitor patients for signs of disrupted homeostasis, such as abnormal vital signs or lab results, to intervene appropriately.
