claimWhen human body temperature exceeds 98.6°F (37°C), the nervous system coordinates a cooling response by dilating blood vessels near the skin and inducing sweat production.
claimWhen human body temperature is too low, the musculoskeletal system generates heat through shivering, while the circulatory system constricts surface blood vessels to conserve warmth.
claimThe respiratory, muscular, and integumentary systems work together to regulate human body temperature and prevent overheating or excessive cooling.
claimSkeletal muscles maintain body temperature by generating heat during metabolic activity.
measurementThe standard human body temperature is 98.6°F (37°C).

measurementWoodchucks are true hibernators whose body temperature can drop from 99 degrees Fahrenheit to as low as 37 degrees Fahrenheit during hibernation.
measurementBats hibernating in caves enter a state of torpor characterized by heart rates dropping to 25 beats per minute, a breathing rate of about one breath per minute, and a near-freezing body temperature.
claimBlack bears hibernate but are not considered 'true hibernators' like woodchucks; they experience lower body temperatures and slower heart rates during the winter denning season to survive cold weather and food scarcity.
