  • The right lung has three lobes, the left only two, because the heart takes the space.
  • Each lung is enclosed by a double-layered pleura with pleural fluid between, which reduces friction as the lung moves.
  • Alveoli are the site of exchange and are thin-walled and richly supplied with capillaries; they are far below the scale of this model.

Chapter numbering moved when NCERT rationalised its books in 2023 and the NTA has revised the NEET syllabus since, so this maps by unit and title. It is a study aid, not a syllabus.
