    • layer of the meninges
  22. Areolar connective tissue
    • A
    • loose tissue found in most organs of the body; consists of weblike collagen,
    • reticulum, and elastin fibers.
  23. Arrector pili
    • Smooth
    • muscle that surrounds each follicle; responsible for “goose bumps,” which pull
    • the hair upward.
  24. Arterioles
    • Small arterial vessels that supply
    • oxygenated blood to the capillaries.
  25. Ascending colon
    • part of
    • the large intestine
  26. Atria
    • Two
    • receiving chambers of the heart; singular form is atrium
  27. Atrial kick
    • Remaining
    • 20% to 30% of blood forced into the right ventricle during atrial contraction
  28. Atrioventricular node (AV node)
    • A
    • group of cells that conduct an electrical impulse through the heart; located in
    • the floor of the right atrium immediately behind the tricuspid valve and near
    • the opening of the coronary sinus
  29. Auditory ossicles
    • Three
    • small bones (malleus, incus, and stapes) that articulate with each other to
    • transmit sound waves to the cochlea
  30. Auricle
    • Also
    • called the pinna; outer ear
  31. Autonomic nervous system
    • Provides
    • unconscious control of smooth muscle organ and glands
  32. Axial skeleton
    • Made
    • up of the skull, hyoid bone, vertebral column, and thoracic cage
  33. Base
    • Top
    • of the heart
  34. Bicuspid valve
    • Left
    • atrioventricular valve in the heart; also called the mitral valve

    • in the liver; composed of electrolytes and iron recovered from red blood cells
    • when they die
  36. Blood
    • Liquid
    • connective tissue; allows transport of nutrients, oxygen, and waste products
  37. Bone
    • Hard
    • connective tissue; consists of living cells and a matrix made of minerals
  38. Bowman’s capsule
    • Located
    • in the renal corpuscle
  39. Brainstem
    • Part
    • of the brain that connects it to the spinal cord; responsible for many of the

    • functions)
  40. Bronchioles
    • Smallest
    • of the passages
  41. Bulbourethral glands
