Document Summary

Provide a framework that supports the body. Provides sites for muscle attachment: we are going to focus particularly on skeletal muscle the muscles that move the bones. Protective covering for certain organs and regions of the body. Certain bones contain red bone marrow which produces new red blood cells (hemopoietic tissue: red bone marrow resides in flat bones, longer bones contain yellow blood marrow (aka fat) Bo(cid:374)e a(cid:272)ts as a sto(cid:396)age (cid:373)ediu(cid:373) a(cid:374)d (cid:862)(cid:271)uffe(cid:396)(cid:863) fo(cid:396) (cid:272)al(cid:272)iu(cid:373) in the blood (homeostasis: calcium is one of the most important molecule of the body it is involved in almost every process in the body.
