  1. Hypertension
    excessively high Blood pressure; criteria vary but it is often considered to be a condition in which systolic pressure exeeds 150 mmHG or diastolic pressure exeeds 90mmHG.
  2. brachial
    Pertaining to the arm proper, the region from the shoulder to elbow.
  3. colloid osmotic pressure
    a proportion of the osmotic pressure of a body fluid that is due to its protein. compare oncotic pressure
  4. net filtration pressure
    a net force favoring filtration of a fluid from a capillary when all the hydrostatic and osmotic pressure of the blood and tissue fluids are taken into account.
  5. capillary
    the narrowest type of vesse in the cardiovascular and lymphatic system; engages in fluid exchanges with surrounding tissues
  6. cerebrovascular accident
    the loss of blood flow to any part of the brain due to obstruction or hemorrhage of an artery, leading to the necrosis of nervous tissue; also called stroke or apoplexy.
  7. fenestrated
    Perforated with holes or slits, as in fenestrated blood capillaries and the elastic sheets of large arteries
  8. aneurysm
    a weak, bulging point in the wall of a heart chamber or blood vessel, presenting a threat of hemorrhage.
  9. capillary exchange
    The process of fluid transfer between blood stream and tissue fluid
  10. oncotic pressure
    the difference between the colloid osmotic pressure of the blood and that of the tissue fluid, usually favoring the fluid absorption by the blood capillaries. compare colloid osmotic pressure
  11. perfusion
    the amount of blood supplied to a tissue in a given peroid of time
  12. renal
    pertaining to the kidney
  13. artery
    any blood vessel that conducts blood away from the heart
  14. axillary
    pertaining to the armpit
  15. Lingual
    pertaining to the tongue, as in lingual papillae.
  16. renin
    an enzyme secreted by the kidneys in response to hypotension; converts the plasma protein angiotensinogen to angiotensin I, leading indirectly to a raise in BP.
  17. systolic pressure
    the peak arterial blood pressure measured during ventricular systole
  18. embolism
    the obstruction of blood vessel by an embolus.
  19. adventitia
    loose fibroconnective tissue forming the outermost sheath around organs such as a blood vessel or the esophagus
  20. circulatory system
    an organ system consisting of the heart, blood vessels, and blood. compare cardiovascular system
  21. angiogenesis
    the growth of new blood vessels
  22. anaphylactic shock
    a severe systemic form of anaphylaxis involving bronchiolar constriction, impaired breating, vasodilation, and rapid drop in blood pressure with a threat of circulatory failure
  23. diffusion
    the movement of molecules resulting from their spontaneous thermal vibration; net diffusion is the movement of more molecules in one direction than in another
  24. circulatory shock
    a state of cardiac output inadequate to meet the metabolic needs of the body
  25. hepatic
    pertaining to the liver
  26. aorta
    a large artery that extends from the ventricle to the lower abdominal cavity and gives rise to all arteries of the systemic circulation
  27. arcuate
    making a sharp L- or U= shaped bend, as in the arcuate arteries of the kidneys and uterus.
  28. hyperextension
    a joint movement that increases the angle between two bones beyoned 180 degrees.
  29. autoregulation
    the ability of a tissue to control its own blood supply through vasomotion or angiogenesis.
  30. varicose vein
    a vein that has become permanently distended and convoluted due to a loss of competence of the venous valves; expecially common in the lower extremity, esophagus, and anal canal.
  31. carotid body
    a small cellular mass immediately superior to the branch in the common carotid artery, containing sensory cells that detect changes in blood ph and carbon dioxide and oxygen content
  32. hepatic portal system
    a network of blood vessels that connect capillaries of the intestines to capillaries (sinusoids) of the liver, thus delivering newly absorbed nutrients directly to the liver
  33. lumbar
    pertaining to the lower back and sides, between the thoracic cage and pelvis.
  34. VAD stands for?
    a vessel of duct
  35. anastromosis
    an anatomical convergence, the opposite of branch; a point where two blood vessels merge and combine their bloodstreams or where two nerves or ducts converge
  36. systemic
    widespread or pertaining to the body as a whole, as in the systemic circulation.
  37. vein
    any blood vessel that carries blood toward either atrium of the heart.
  38. ophthalmic
    pertaining to the eye or vision; optic
  39. vasomotion
    collective term for vasoconstriction and vasodilation
  40. venule
    the smallest type of vein, receiving drainage from capillaries.
  41. arteriole
    a small arterythat empties into a metarteriole or capillary
  42. shock
    circulatory shock, a state of cardiac output that is insufficient to meet the body's physiological needs, with consequences ranging from fainting to death.
  43. intercellular
    between cells
  44. formula for net filtration pressure (FNP)
    oncotic pressure-hydrostatic pressure-Net filtration pressure
