"living hearts being cut open (for good reasons)"
Reason:
the purpose of this was not just to cut it open and just have fun watching it, but we were actually examining some features of the heart that have very special purposes for keeping us alive.
I've learnt that even the most ugly of insides living inside your body, their purpose is actually more important then you'll actually think.
How?
1.
I've learnt that the rhythm the heart beats actually controls either your breathing or something, and even if the heart goes A LITTLE out of tune, then that could actually make your breathing go way out of hand.
2.
Bloods vessels help the blood to travel everywhere along the body, the arms, the stomach and the legs.
with the after effects allowing those body parts to move around (I think...) because with blood, comes life, and without life or anything else you'll be dead.
so if you don't have blood anywhere in the body, even just 1 body part can be dead
3:
Blood is a mixture of 2 things.
Oxyegen (breathing) and plasma (a different coloured blood)
