Conduction physics thermoregulation

Extreme weather can significantly affect the body’s ability to regulate temperature. Hypothermia occurs when a person has exposure to extremely cold temperatures for an extended period. In these instances, the body loses heat quickly, and heat production cannot keep up, causing a dip in body temperature. In … See more When a person has an infection, harmful microorganisms invade the body and multiply. These pathogens can thrive at typical body temperatures, but an increased temperature makes it more difficult for some of … See more Infants and older adults have a higher riskTrusted Sourceof thermoregulation disorders. The reason for this is that these individuals have a lower muscle mass, a decreased shiver … See more Certain medications can disrupt thermoregulation as a side effect, causing a temporary rise in body temperature. Some people refer to this as “drug fever.” Examples of medications that can have this effect include: 1. … See more WebHeat conduction (as opposed to electrical conduction) is the flow of internal energy from a region of higher temperature to one of lower temperature by the interaction of the adjacent particles (atoms, molecules, ions, electrons, etc.) in the intervening space. Note: it's the rate ( P or Φ) at which heat is transferred, not the amount ( Q) of ...
