    One of several small arteries that supply heart with freshly oxygenated blood.
  22. Vena Cava (cranial/caudal)
    • Cranial: Major vein returning deoxygenated blood from the upper extremities of the body to the right atrium of the heart.
    • Caudal: Major vein returning deoxygenated blood from the lower extremities of the body to the right atrium of the heart.
  23. Auricle
    flap-like outer region covering the cranial portion of the atrium.
  24. L R Atrium
    Chamber of the heart that receives blood.
  25. Common Carotid Arteries
  26. Pulmonary Artery/Vein
    • Artery: short blood vessels which [in adult] carry deoxygenated blood from the R ventricle of the heart to the lungs
    • Veins: blood vessels which [in adult] carry oxygenated blood from lungs to the left atrium of heart.
  27. Aorta
    Large artery arising from the left ventricle that distributes blood the the regions of the body.
  28. Ductus Arteriosus
    Short connection joining pulmonary trunk with the aorta and allowing a portion of the blood from trunk to enter the aorta instead of flowing to the lungs, found only in fetus.
  29. ???chiocephalic Vein/Trunk (Artery)
  30. Juglar Veins (Internal & External)
  31. Cephalic Vein
  32. Thyrocervical Trunk (Artery) [Missing]
  33. Adrenal Gland
    Endocrine gland located medial to the kidney, produces hormones which mediate responses to stressful situations and control blood pressure and carbohydrate and protein metabolism.
  34. Kidneys
    Excretory unit, filters blood creating highly concentrated metabolic by-product (urine) which is sent to urinary bladder. Also maintains homeostatic balance of salts, fluid, and ions within the body.
  35. Ureter
    Tube that transports urine from kidney to the urinary bladder for storage.
  36. Urethra
    Tube that leads from the urinary bladder to the outside of the body, transports urine and semen.
  37. Urinary Bladder
    Membranous sac that stores excreted urine from kidneys.
  38. Bulbourethral Glands
    Accessory glands of the male reproductive system located at base of penis and urethra that produce alkaline secretions that assist in lubrication during intercourse and neutralize acidity of vagina.
  39. Epididymis
    Highly coiled tubule system that cups around the testis and serves as storage and transportation canal for mature sperm.
  40. Penis
    External reproductive organ of male, deposits semen in reproductive tract of female and carries excretory wastes in form of urine out of body.
  41. Seminal Vesicles
    Accesory glands of male system located near the junction of urthra and base of penis; in pigs they secret alkaline fluids that neutralize acidity of vagina and nutrients to promote sperm motility and hormones to stimulate uterine contractions.
  42. Scrotal Sacs
    Pouch extending from the caudal region of male, contains 2 testes. Their presence helps testes to be slightly lower in temperature than rest of abdominal cavity.
  43. Umbilical Cord
    Attachment between maternal placenta and fetus which gasses, nutrients, and nitrogenous wastes are transported.
  44. Urogential Opening
    Opening of urethra (in males) or the urogenital sinus (in females) through which urine passes and is eliminated from the body.
  45. Soft Palate
    Cartilaginous region of roof of mouth that separates oral cavity from the nasal passageway, located towards back of mouth.
  46. Sublingual Gland
    Salivary gland located underneath the skin alongside the tongue of the pig.
  47. Tongue Papillae
  48. Epiglottis
    Cartilaginous flap that covers the glottis to prevent food from entering the larynx and trachea when swallowing.
  49. Glottis
    Opening in oral cavity that leads from nasopharynx to the larynx & trachea
  50. Pancreas
    Granular organ located along left margin of the duodenum. Produces digestive enzmes and a variety of hormones.
  51. Pancreatic Duct
    Canal which digestive enzymes from pancreas are transported to the duodenum.
  52. Common Bile Duct
    Tubule through which bile is transported from liver to gallbladder and gallbladder to duodenum.
  53. Spleen
    Ductless vascular organ in abdomina cavity. Stores blood, recycles worn out red blood cells and makes lymphocytes.
  54. Duodenum
    First portion of the small intestin; functions primarily in final stages of chemical digestion and begins process of nutrient absorption.
  55. Ileum
    Distal portion of small intestine extending from the jejunum to the cecum; responsible for absorption of nutrients.
  56. Jejunum
    Middle portion of small intestine extending from duodenum to ileum, responsible for nutrient absorption.
  57. Cecum
    Blind projection located at the junction of ileum and colon, serves as a sac where fermentation of cellulose occurs.
  58. Colon
    From cecum to rectum, large intestine, reabsorption of water that has been added through digestive process.
  59. Rectum
    Reabsorb water and produce dry, concentrated feces.
  60. Anus
    Opening of rectum through which undigested food (feces) expelled from body
  61. Subscapular Vein
  62. Subclavian Vein/Arteries
  63. Hepatic Portal Vein
    Large portal that carries nutrient rich and toxin laden blood from small intestines and pancrease to liver for detox and regulation before blood goes throughout rest of the body.
  64. Mesenteric Arteries/Veins
  65. External Iliac Veins/Arteries
  66. Umbilical Artery/Vein
    • Artery: Paired vessels that carry blood from fetus to the placenta
    • Vein: Single vessel that carries O2 and nutrient rich blood to the fetus from the fetal side of the placenta.
  67. Scrotum
  68. Testis
    Produces sperm and hormones (reproductive organ of male)
  69. Vas Deferens
    Tube connected to the epididymis that transports sperm from the testis through the epididymis to the urethra during ejaculation.
  70. Ovaries
    Reproductive organ in females, produces eggs and hormones
  71. Oviducts
    Tube by which the egg, leaving the ovary, is carried to the uterine horns
  72. Uterus
    Region which embryonic development occurs.
  73. Vagina
