The human body always works to remain in homeostasis. One form of homeostasis is thermoregulation. Body temperature varies in every individual, but the average internal temperature is 37.0 °C (98.6 °F). [1] Sufficient stress from extreme external temperature may cause injury or death if it exceeds the ability of the body to thermoregulate.
Allen's rule - Hare and its ears on the Earth [1]. Allen's rule is an ecogeographical rule formulated by Joel Asaph Allen in 1877, [2] [3] broadly stating that animals adapted to cold climates have shorter and thicker limbs and bodily appendages than animals adapted to warm climates.
Thermoregulation is the ability of an organism to keep its body temperature within certain boundaries, even when the surrounding temperature is very different. A thermoconforming organism, by contrast, simply adopts the surrounding temperature as its own body temperature, thus avoiding the need for internal thermoregulation.
The opposite condition, when body temperature decreases below normal levels, is known as hypothermia. It occurs when the body loses heat faster than producing it. The core temperature of the body normally remains steady at around 36.5–37.5 °C (97.7–99.5 °F).
Kinetic and potential energy are in phase, and the energy is stored & released from a spring-like limb during foot contact, [100] achieved by the plantar arch and the Achilles tendon in the foot and leg, respectively. [102] Again, the whole-body kinetics are similar to animals with more limbs. [101]
A woman exercising. In physiology, motor coordination is the orchestrated movement of multiple body parts as required to accomplish intended actions, like walking.This coordination is achieved by adjusting kinematic and kinetic parameters associated with each body part involved in the intended movement.
With higher temperature and humidity, viruses can’t survive outside a host as long. Research suggests flu viruses in high humidity can cling to water molecules and then fall out of the air. That ...
Temperature also modulates the activity of the Na + /K +-ATPase [citation needed]. The Na + /K +-ATPase is a P-type pump that extrudes 3Na + ions in exchange for 2K + ions for each hydrolytic cleavage of ATP. This results in a net movement of positive charge out of the cell, i.e. a hyperpolarizing current. The magnitude of this current is ...
