Breathing and Exchange of gases summary notes + mastering multiple choice questions + NCERT exemplar question + statement based questions + matching type questions + assertion and reasons all in one with brief explanation
Breathing involves the intake of oxygen and expulsion of carbon dioxide. In humans, it occurs through inhalation (air enters lungs, oxygen diffuses into bloodstream) and exhalation (carbon dioxide exits). Gas exchange happens in the alveoli of the lungs, where oxygen diffuses into blood vessels and carbon dioxide diffuses out.
