Inhalation is the active intake of air, involving contraction of the diaphragm and expansion of the lungs. Exhalation is passive, with relaxation of the diaphragm, reduction in lung volume, and expulsion of air due to elevated pressure. For a more detailed difference, students can use the NCERT Class 11 Biology Chapter 14 Notes Breathing and Exchange of Gases.
