Lead poisoning is distributed via the blood to which tissue?

Explanation:
Lead in the bloodstream is carried to various tissues, but it preferentially deposits in bone. This happens because lead mimics calcium and readily substitutes for calcium in the hydroxyapatite of bone, forming a long-lasting reservoir with a very long half-life. While lead can affect soft tissues like the brain and liver, bone is the primary tissue where it is stored and gradually released back into the bloodstream over time.
