Kavi Follows a Breath of Air

Kavi takes a deep breath 🌬️ and suddenly wonders, "Where does the air GO?" So Kavi follows one breath on an amazing trip! "First the air rushes in through my nose, down my windpipe, and into my two spongy lungs. In there, the oxygen jumps out of the air and into my blood! Then my heart pumps that blood all around me, carrying oxygen and food to every single part — from my brain to my toes! 🫁❤️ Come and follow a breath through you!"
