    6810   Transport  The Directed Movement of Substances (such As Macromolecules Small Molecules Ions) Into Out of or Within a Cell or Between Cells or Within a Multicellular Organism by Means of Some Agent Such As a Transporter or Pore. 
    5576   Extracellular Region  The Space External to the Outermost Structure of a Cell. For Cells Without External Protective or External Encapsulating Structures This Refers to Space Outside of the Plasma Membrane. This Term Covers the Host Cell Environment Outside an Intracellular Parasite. 
    5737   Cytoplasm  All of the Contents of a Cell Excluding the Plasma Membrane and Nucleus But Including Other Subcellular Structures. 
    5179   Hormone Activity  The Action Characteristic of a Hormone Any Substance Formed in Very Small Amounts in One Specialized Organ or Group of Cells and Carried (sometimes in the Bloodstream) to Another Organ or Group of Cells in the Same Organism Upon Which It Has a Specific Regulatory Action. the Term Was Originally Applied to Agents with a Stimulatory Physiological Action in Vertebrate Animals (as Opposed to a Chalone Which Has a Depressant Action). Usage Is Now Extended to Regulatory Compounds in Lower Animals and Plants and to Synthetic Substances Having Comparable Effects; All Bind Receptors and Trigger Some Biological Process.
