Anatomy and Physiology I
Basal metabolic rate (BMR) is the amount of energy expended while at rest in a neutrally temperate environment, in the post-absorptive state, meaning that the digestive system is inactive. BMR is crucial for understanding energy and heat balance in the body, as it represents the minimum amount of energy needed to maintain basic physiological functions such as breathing, circulation, and cellular production. This rate can be influenced by various factors, including age, gender, muscle mass, and hormonal levels.
