Chapter 6: Cardiorespiratory System
"Cardiorespiratory System" is a chapter of about ten pages on the heart, lungs and blood circulation and how they work during exercise. Students are likely to measure pulse and breathing rate at rest and after activity, to see how fitness changes them and to learn why endurance training matters. It builds on the previous chapter on the body and links with the Science chapters on life processes. Recording and comparing their own data makes it concrete.
This is chapter 6 of 23 in Khel Praveen, the Class 9 Physical Education and Well Being textbook, in the Science and Sports section, and begins on page 44 of the printed 2026-27 book. It follows "Understanding Our Body" and is followed by "Growth, Development, and Maturation".
Understanding and activity go together in "Cardiorespiratory System". The book asks students to appreciate the history, ethics and science behind the games they play as well as to practise them, and to discuss, research and reflect. Safe practice, inclusion and fair play are stressed. The chapter works well with short projects, discussion, demonstration and a connection to the student's own activity.
After "Cardiorespiratory System", ask your student what they found interesting and what they would change in their own routine. Conversations like this extend the classroom discussion to the home. Make sure students drink water, rest properly and wear suitable clothing.
