About this worksheet
Students label seven parts of the respiratory system on a diagram of a head and chest, then match each part to its job. The word bank holds nose, mouth, trachea, bronchi, lungs, alveoli and diaphragm. Numbered lines 1 to 7 point to the parts, with an inset circle for the alveoli. Page 2 gives seven job descriptions, from the windpipe to tiny grape-like air sacs. An answer key is on page 3.
