Which of the following terms means air in the chest?
A) pneumothorax

Pneum/o means air and -thorax means chest; therefore, pneumothorax means air in
the chest. Hem/o means blood; thus, hemothorax means blood in the chest. Py/o means pus;
hence, pyothorax means pus in the chest. Pulm/o is not a combining form, so pulmothorax is not
a medical term.
