Some people have two inside of them.
A few had more than that.
Yup pretty common.
Huh. Gross.
Covered in blood
Even more strange, structure is a secondary function of our skeleton. It's primary function is as a source of calcium for muscle contraction
Is that true? Primary and secondary? Not just two functions? I'm not saying you're wrong, I'm just curious what you mean.
Is that true of creatures with exoskeletons? Is an exoskeleton even made of the same kind of material as the endo-variety? I failed hs biology lol
