  • divides
  • In the fourth week of development of the human embryo as the respiratory bud grows, the trachea separates from the foregut through the formation of tracheoesophageal ridges which fuse to form the tracheoesophageal septum and this separates the future trachea from the oesophagus and divides the foregut tube into the laryngotracheal tube.

  • tissue
  • The trachealis muscle joins the ends of the rings and these are joined vertically by bands of fibrous connective tissue - the annular ligaments of trachea. (wikipedia.org)
  • doctors
  • Doctors culture a custom-made trachea from plastic fibers and human cells, and successfully implant it into a child who was born without the organ. (the-scientist.com)

  • rings
