  1. an mineralocorticoid hormone that increases the reabsorption of both sodium and water from the kidneys or renal tubules; these hormones conserve more fluid when there is a fluid deficit in the body
    Aldosterone
  2. a negatively charged ion such as chloride
    anion
  3. loss of appetite
    anorexia
  4. increases the absorption of water in the renal tubules
    antidiuretic hormone (ADH)
  5. abnormal accumulation of fluid in the abdominal cavity
    ascites
  6. is a powerful vasodilator, and a protein (polypeptide) hormone secreted by heart muscle cells.[1][2] It is involved in the homeostatic control of body water, sodium, potassium and fat (adipose tissue). It is released by muscle cells in the upper chambers (atria) of the heart (atrial myocytes),
    in response to high blood pressure. ANP acts to reduce the water, sodium and adipose loads on the circulatory system, thereby reducing blood pressure
    atrial natriuretic peptide
  7. characterizes the capacity of a blood vessel wall to allow for the flow of small molecules (ions, water, nutrients) or even whole cells (lymphocytes on their way to the site of inflammation) in and out of the vessel
    capillary permeability
  8. a strong muscle contraction of the hand or foot
    carpopedal spasm
  9. a positively charged ion such as sodium
    cation
  10. the movement of molecules from an areaof high concentration to low concentration
    diffusion
  11. A diuretic provides a means of forced diuresis which elevates the rate of urination. There are several categories of diuretics. All diuretics increase the excretion of water from bodies
    diuretic
  12. abnormal cardia rhythm
    dysrhythmia
  13. a record of conduction in the heart
    electrocardiogram
  14. fludi outside the cells; includes intravascular and interstitial fluids
    extracellular
  15. passage of a fluid through a permeable membrane whose spaces do not allow certain solutes to pass; passage is from an area of higher pressure to one of lower pressure
    filtration
  16. is responsible for certain metabolic processes and other activities of the autonomic nervous system. It synthesizes and secretes certain neurohormones, often called hypothalamic-releasing hormones, and these in turn stimulate or inhibit the secretion of pituitary hormones. The hypothalamus controls body temperature, hunger, thirst,atigue, sleep, and circadian cycles.
    hydrogen ions
  17. force exerted by a fluid against the container wall
    hydrostatic pressure
  18. a solution with a greater concentration of solutes or higher osmotic pressure than that inside the cells present in the solution
    hypertonic / hyper - osmolar
  19. excess of plasma
    hypervolemia
  20. is a portion of the brain that contains a number of small nuclei with a variety of functions. One of the most important functions of the hypothalamus is to link the nervous system to the endocrine system via the pituitary gland
    hypothalamus
  21. having a lesser concentration than the solution with which it is being compared
    hypotonic / hypo - osmolar
  22. decreased blood volume
    hypovolemia
  23. is a solution that bathes and surrounds the cells of multicellular animals. It is the main component of the extracellular fluid, which also includes plasma and transcellular fluid. The interstitial fluid is found in the interstitial spaces, also known as the tissue spaces.
    interstitial fluid
  24. fluid inside the cells
    intracellular
  25. within blood vessels
    intravascular fluid
  26. having about the same concentration as the solution with which it is being compared
    isotonic / iso-osmolar
  27. closure of the larynx obstructing the airway
    laryngospasm
  28. describes an equivalent as the amount of a substance that will react with one gram of hydrogen, or with eight grams of oxygen
    milliequivalent (mEq)
  29. A nonvolatile acid (also known as a fixed acid or metabolic acid) is an acid produced from sources other than carbon dioxide, and is not excreted by the lungs. They are produced from e.g. an
    incomplete metabolism of carbohydrates, fats, and proteins. All acids produced in the body are nonvolatile except carbonic acid, which is the sole volatile acid. Common nonvolatile acids in humans are lactic acid, phosphoric acid, sulfuric acid, acetoacetic acid, and beta-hydroxybutyric acid.
    nonvolatile metabolic acids
  30. sensory nerve receptors stimulated by changes in fluid and electrolyte concentrations
    osmoreceptor
  31. the force that draws water through a semi-permable membrane from a solution of lower solute concentration to a solution of higher concentration
    osmosis
  32. drawing power for water or the attraction for water exerted by solute particles
    osmotic pressure
  33. abnormal sensation
    parensthesias
  34. tension of skin determined by hydration
    skin turgor
  35. repeated skeletal muscle contrations or spasms, seen in the extremities and face, related to increased irritability of the nerves, often associated with hypocalcemia
    tentany
  36. passive through cells
    transcellular
