Integumentary System-Anatomy 

________ canal- transverse to exterior surface.

________- break down bone.

________- residue from sweat glands; blocks toxins /antibacterial.

________ remove calcium from blood to build bone.

________ is needed for skeletal and cardiac muscle contraction, nerve impulses, and blood clotting.

________- regulates body temperature.

________- hyaline at joints.

________- ultra small canals connecting lacunae to haversian, blood and lymph.

________- covers the long bone.

________- hollow space in diaphysis.

________ is the largest organ in the body.

________- bone forms from cartilage.

________ matrix- growth point for hair and nails.

________- dense fibrous irregular (collagen)
