ANT-1 Lecture Notes - Lecture 14: Miscarriage, Fetus, Frostbite
Document Summary
Acclimatization (response): short term* response to environmental stimuli to. Ex: not working in heat, dressing according to weather keep the body working properly. Developmental: when stress is experienced during a period of growth or development fetus or child. Change that occurs is not inherited but ability to change is inherited. Experienced at individual level, can be observed at population level. Ex: increased chest size at high altitudes. Genetic (evident in populations): inherited, not reversible. Purpose: maintain homeostasis ability to maintain equilibrium. Humans deal with heat better than cold because humans evolved in equatorial africa. However subsets in population show variation of tolerance. Sweating: everyone has equal # of sweat glands, supposed to cool you down, lose nutrients and fluid. Vasodilation: when capillaries near skin surface dilate when overheated, which increases flow of blood away from core and out to surface, turning red when working out. Shivering: muscle movement to generate heat, takes a lot of energy.
