Human beings don’t live inside of someone else and require their blood, organs and body to survive. Embryos do. Embryos have no frontal cortex, sentience and have less neural activity than most clinically brain dead individual. Human beings do. Embryos have no working Integumentary, Skeletal, Muscular, Nervous, Endocrine, Cardiovascular, Lymphatic, Respiratory, Digestive, Urinary, or Reproductive Systems. Human beings do. Therefore, embryos ≠ human beings. They are human organisms.
