Clues

  • A chemical substance which covers the surface of the alveoli. It reduces surface tension and prevents the alveoli from sticking together and collapsing when breathing out (10)
  • A reaction involving the hydrolysis of glucose to form ATP (11)
  • Has a skeleton made entirely of cartilage and has 5 Gill clefts just behind the head on each side which open at Gill slits (13, 4)
  • The flap which covered the gills (9)
  • The process of bringing air or water to and from an exchange surface (11)
  • The process of bringing oxygen into the cells and removing carbon dioxide from them (3, 8)
  • The tracheae branch repeatedly until they end as very fine, thin walled .... (10)
  • Valves that can open and close to allow gas exchange and reduce water loss (9)
  • What supports the airways and prevents them from collapsing during low pressure? (it is c shaped) (9)
  • Where in the lead are the stomata found? (5, 9)
