Across
  1. 2. - Identify the structure labelled B with an arrow. (Structures A and B are generally found together)
  2. 4. - Identify the individual structure labelled C with an arrow (Found at the very end of the respiratory pathway)
  3. 5. - What structure is being pointed out by the arrow for A? (Supporting structure – keeps airways open)
  4. 8. - What is being indicated by the black pathways in this figure?
  5. 9. - What cells are indicated by the arrows? These cell types are present in the structure 1C’s membrane and can be seen in the section view; it’s difficult to discretely differentiate in this image.
  6. 12. - Identify the structure enclosed in circle A (It is relatively smaller and thinner than upper tubes)
  7. 13. - Determine which cell the arrow points towards (Function – They are secretory cells found in the structure 1A)
Down
  1. 1. - Identify the structures that are enclosed/indicated within the black circle. (The site of exchange between arteries and veins)
  2. 3. - What structure is being pointed out by the arrow for C? (It’s the innermost layer of structure 1A, consisting of multiple cell types)
  3. 6. - What structure is being pointed out by the arrow for B?
  4. 7. - What is indicated by the arrow; it’s found towards the lumen of structure 1A. (And secreted by cells shown in 3)
  5. 10. - Identify the entire structure labelled A with an arrow.
  6. 11. - Identify the structure enclosed in circle B (It is usually found alone)
