As you study zoology further you will come to relearn that veins bring blood back to the lungs,
Across the kingdom animalia & a few others including Aves & Reptilia, Mammalia & Chordata,
From lungs the re-oxygenated blood is re-pumped around the body by our rhythmic heartbeats.

In my body it's a bit different I guess, yes it's different!

Your name has crept up my veins and I just feel your Kreepy name sounding with every heartbeat.
