After each activation, the coroutine is suspended precisely at the yield keyword, waiting for a value to be sent. The line coro_avg.send(10) provides that value, causing the coroutine to activate. The yield expression resolves to the value 10, assigning it to the term variable. The rest of the loop updates the total, count, and average variables. The next iteration in the while loop yields the average, and the coroutine is again suspended at the yield keyword.
