Advanced Physiology 100% Verified Study Guidelines 2026

Advanced Physiology 100% Verified Study Guidelines 2026 What are the fundamental concepts of Physiology? - Correct Answer Homeostasis Feedback Redundancy Integration Define Homeostasis - Correct Answer Maintaining physiological variables within a relatively narrow range, regardless of the extrenal (outside temp.) stress or internal stress (low blood sugar). Two kinds of Feedback - Correct Answer Positive Feedback (1-5%) Negative Feedback (95-99%) The idea of Negative Feedback - Correct Answer When a sensor (thermostat) detects a level (set point) of the output (cold air) of a controller (A/C unit) and leads to LESS OUTPUT. Example of Negative Feedback Scenario - Correct Answer Insulin secretion in response to high blood glucose, when blood glucose levels drop, insulin secretion stops. Positive Feedback - Correct Answer LEADS TO MORE OUTPUT Example of Positive feedback scenario - Correct Answer Oxytocin released in response to contractions of uterus and leads to MORE contractions of uterus Define Redundancy - Correct Answer having more than one system in place to HELP attain the goal of homeostasis. Example of Redundancy: - Correct Answer Insulin/Glucagon primary mechanism
