Henry's law

(noun)

At a constant temperature, the amount of a given gas that dissolves in a given type and volume of liquid is directly proportional to the partial pressure of that gas in equilibrium with that liquid.

    • Henry's law can be put into mathematical terms (at constant temperature):
    • The main application of Henry's law in respiratory physiology is to predict how gasses will dissolve in the alveoli and bloodstream during gas exchange.
    • Explain the way in which Henry's law relates to gas exchange in the respiratory system
  • External Respiration

    • Based on Henry's law, the greater solubility of carbon dioxide in blood compared to oxygen means that diffusion will still occur very rapidly despite the lower partial pressure gradient.
  • Dalton's Law of Partial Pressure

    • Dalton's law of partial pressures states that the pressure of a mixture of gases is the sum of the pressures of the individual components.
    • Dalton's law states that the total pressure exerted by the mixture of inert (non-reactive) gases is equal to the sum of the partial pressures of individual gases in a volume of air.
    • This empirical law was observed by John Dalton in 1801 and is related to the ideal gas laws.
    • Dalton's law is only truly applicable in every situation to ideal gasses.
    • Infer from Dalton's law of partial pressure the sum of partial pressures in alveoli
  • Cardiac Output

    • Starling's law of the heart states that the SV of the heart increases in response to an increase in EDV when all other factors remain constant.
    • The main implication of this law is that increases in blood volume or blood return to the heart will increase cardiac output, which will lead to an increase in MAP.
  • Autopsy

    • In United States law, deaths are placed in one of five manners: natural, accident, homicide, suicide and undetermined.
    • In some jurisdictions, the "undetermined" category may include deaths in absentia, such as deaths at sea and missing persons declared dead in a court of law; in others, such deaths are classified under "other. " But, medical examiners also attempt to determine the time of death, the exact cause of death, and what, if anything, preceded the death, such as a struggle.

    • Once a term is located, the response will be subdivided into several basic formats, including General usage, Medicine, Law, Business, and others.The use of a medical dictionary or Internet search engine is most helpful in learning the exact meaning of a medical term.
  • Stages of Bone Development

    • Repeated stress, such as weight-bearing exercise or bone healing, results in the bone thickening at the points of maximum stress (Wolff's law).
  • Exercise and Bone Tissue

    • According to Wolff's law, bone in a healthy person or animal will adapt to the loads it is placed under.
  • Adjustments at High Altitude

    • Due to Boyle's law, at higher altitude the partial pressure of oxygen in the air is lower, and less oxygen is breathed in with every breath.
