Grasshopper is an insect and like all insects, it has tracheal system to supply oxygen to tissues.

Tracheae are branched tubular non-collapsible air passages, lined by chitin.
Paired openings are there in the tracheal system for inhalation and exhalation of air. Such openings are called spiracles.
In grasshopper, two pairs of spiracles are there in the thorax and another eight pair are present in the abdomen.
Terminal branches of the tracheal system are called tracheoles, which are not more than one micron in diameter.
Cells (including muscles) of insect's body are supplied by oxygen through trachea and tracheoles. The tubules also help in removing carbon dioxide from tissues.
