Anatomy and PhysiologyAnatomy – What?Where?Science of body structure and the relationshipsamong structuresPhysiology – How?Science of body functionBoth are studied together as a unitBody structures are designed specifically to carryout a specific functionThe structural design of a body part determineswhat kind of function it can perform
Levels of Organization: Atom toOrganismAtoms:building blocks of matterEx. hydrogen, oxygen, nitrogen, carbonMolecules:two or more combined atomsPerform biochemical functionsCells:building blocks of a living organismComposed of moleculesTissues:cells that do similar functions togetherEx. muscle tissue, epithelial tissueOrgans:tissues that work together to perform a functiontogetherEx. heart, lungsBody system:related organs that work together to performa functionEx. digestive system, nervous systemOrganism:made up of all body systemsEx. human being
