The flashcards below were created by user melissauri on FreezingBlue Flashcards. What would you like to do?


  1. Urogenital papilla

    conversion of excess glucose (just after absorbing it into the blood) into glycogen in order to store it.

    conversion of glycogen back into glucose when blood glucose levels fall (hours after a meal)

    production of various blood enzymes, clotting factors, etc e.g. fibrinogen, thronbin, and albumin

    detoxifies many poisons (such as nicotine, alcohol, acetaminophen, ibuprofen)
  24. gall bladder
    stores bile and sends it to the duodenum when CCK is in the blood
  25. stomach
    stores food until ready to be digested in the duodenum

    site of initial breakdown of protein using an enzyme call pepsin
  26. pancreas
    produces most digestive enzymes and sends it through the pancreatic duct to the duodenum.(exocrine)

    produces sodium bicarbonate (base) and sends it through the pancreatic duct to the duodenum in order to raise the PH of the chyme coming from teh acidic stomach (exocrine) ph 1-2 to about ph8

    Produces insuline and secretes it into the blood in order to control blood glucose levels (endocrine)
  27. spleen
    serves as reservoir for about 25% of the blood at any one time -can be put into the circulatory system vessels when blood pressure drops dramatically such as in an accident

    has white blood cells that fight pathogens and phahocytize red blood cells
  28. duodenum
    Site of most of the enzymatic hydrolysis of food

    produces secretin, CCk, and GIP
  29. pyloric sphincter
    valve that controls the rate at which chime moves from the stomach to the duodenum
  30. Ileum
    absorption of nutrients
  31. cecum
    First chamber of large intestine.

    Final absorption of water

    Harbors various which produce vitamins K and B
  32. appendix
    In pigs, it harbors bacteria that breaks down cellulose using the enzyme cellulase
  33. Colon (bloiled portion and descending part)
    Final place for water absorption.

    Houses bacterial that produces vitamins K and B
  34. Kidneys
    maintain proper water and electrolyte balance

    filters the blood of metabollic wastes

    keep you hydrated, keep blood isotonic to your cells
  35. descending aorta
    takes oxygenated blood from heart to tissues inferior to the heart
  36. renal artery
    to supply kidneys into the inferior vena cava
  37. renal vein
    to drain blood from the kidneys into the inferior vena cava
  38. inferior vena vaca
    to bring oxygenated blood to right atrium from placenta
  39. ureter
    Let urine flow from teh renal pelvis to the urinary bladder
  40. umbilical arteries
    to carry deoxygenated blood from fetus to the mother
  41. urinary bladder
    store urine
  42. umbilical vein
    to bring oxygenated blood from mother to the fetus
  43. pulmonary trunk
    in pigs, it takes oxygenated blood from heart to the descending aorta
  44. left pulmonary artery
    When pig is born, it transports deoxygenated blood to the lungs
  45. ductus arteriousus
    it bypasses flow of blood to the lungs. Connects the pulmonary trunk to the descending aorta to bring blood south.
  46. azygous vein
    brings deoxy blood back from the rib cage to the inferior vena caca

  63. urethra/penis
    to transport urine from the urinary bladder out of the body
  64. bulbourethral glands
    produces the alkaline portion of the semen to offset the acidity of the vagina (so that "our" little spermies will be safe and fully functional)
