Answer 1

Cortical bone is the type of bone tissue that is tapped to raise blood calcium when the supply from the day's diet runs short.

Step-by-step explanation:

The lacy crystals of the cortical bone are tapped to raise blood calcium when the supply from the day's diet runs short. Cortical bone tissue is smooth and dense and forms the outer layer of bones. It contains a rigid extracellular matrix with collagen fibers embedded in a mineralized ground substance.
