  12. Deals with the chemical makeup of living organisms and the underlying process of life
  13. Atomic Weight
    The number of protons +neutrons in the atom’s nucleus
  14. Ionic Bond
    A strong electrostatic force that binds the + and – charged ions together
  15. Acid solution
    Releases a hydrogen ion (H+)

  27. What is the most wide-spread and abundant tissue in the body?
  28. Collect their secretory products at the apex/tip of the cell and release products by “pinching
    off”. Causes some cytoplasm loss and damage but quickly repairs.
    Apocrine glands
  29. Collect their secretory products inside the cell and then rupture completely to release product. Cells self-destruct

    Lamellae, lacunae, canaliculi, and haversian canals
  37. What are the canals that connect blood vessels between adjacent, paralle osteons?
    Volkmann canals
  38. What are the tiny branches of hard bone present in calcellous bone?
