There’s a quiet sound inside your chest,
As blood moves fast from your pulmonary artery into the capillaries of your lungs,
Through your pulmonary veins and then into your left ventricle.
I think that’s right, I’m not sure, it’s been so long since I opened a science book and learned something new.
Either way there’s a quiet sound inside your chest,
And whatever’s making it, it means you’re here and alive and warm and you’re you,
You’re you, you’re you.
