A

A type of vertebrate connective tissue consisting of living cells and blood vessels within a hard extracellular matrix composed of calcium phosphate and small amounts of calcium carbonate and protein fibers

25
Q

Endoskeleton

A

Bony and or cartilaginous structures within the body that provide support

26

A

A unique structure that makes lactation possible
