2. What are bones and why are they important?Bones are strong scaffolding that lets us stand and move, protect organs, store minerals, and make blood cells.
3. How do bones grow and change as we get older?Bones grow through two processes: intramembranous ossification for flat bones and endochondral ossification for long bones, with growth plates that close when we reach adulthood.

Osteoblast: A cell responsible for synthesizing new bone matrix, playing a crucial role in bone formation.
Osteoclast: A large multinucleated cell that resorbs bone tissue, essential for bone remodeling and calcium homeostasis.
Hematopoiesis: The process of blood cell formation, occurring primarily in the red bone marrow.
