Phospholipid Bilayer → Low permeability to water-soluble substances (e.g. ions, glucose, and amino acids), but permeable to lipid-soluble substances (e.g. fatty acids, oxygen, and carbon dioxide).
Innate → Crisis of fever occurring at the end of febrile condition. Patient has 105 °F temperature, hypothalamus trying to maintain 98.6 °F and is still hot, leads to intense sweating and vasodilatation causing the skin to be hot.
Robert Hooke → Prolonged heat exposure with high humidity. Body gains heat by radiation and convection while evaporative cooling is retarded. Can lead to convulsions, coma, and death.
Heat Loss from Skin → Prolonged heat exposure with high humidity. Body gains heat by radiation and convection while evaporative cooling is retarded. Can lead to convulsions, coma, and death.
Leeuwenhoek (1632-1723) → Coined the term "homeostasis" - the body's tendency to maintain relatively stable internal conditions (the CENTRAL unifying concept of physiology).
