"Here, have a heart"

That's what one of our professors said as she handed me our cadaver's heart.  It's pretty amazing when you think about how much the heart does, and that it never gets to rest.  There are so many things that have to go exactly as planned...and that's just one part of the body.    We're also dissecting the lungs; two of the cadaver's had lung cancer - it had metastasized and there are tumors attached to the inside of the rib cage (one of those was a surprise - not listed as the cause of death).  We're learning about how cancer develops - it's weird that we can understand how it happens.  Our bodies are an intricate combination of delicate structures and exact reactions, yet we have so much resilience.  Even science proves that we can't be the result of some random accident.    Jen
