1Introduction to Anatomy and Physiology Chapter 1Introduction to Anatomy and Physiology
2Anatomy Examines the morphology (or structures) of the body. Form and organization of organisms.
3Physiology Examines the functions of the body. What do structures do? Why do structures do the things they do?
4Anatomy and Physiology Anatomy and physiology are interconnected and depend on one another for life to exist. (Structure is related to function.)
5Examining Organisms as Parts to Whole AtomsBuilding blocks of matter.Composed of subatomic particles.Form molecules which group together to form macromolecules.
6Examining Organisms as Parts to Whole CellsBasic units of structure and function in organisms.Vary in characteristics such as size and shape.All cells contain organelles that carry out specific functions.Remember that organelles are made out of large molecules such as proteins, carbohydrates, lipids, and nucleic acids.Most cells have a complete set of genetic instructions but only use a subset of the instructions, which allows the cell develop specialized functions.
7Examining Organisms as Parts to Whole TissuesMasses or layers of cells that all have similar functions.
8Examining Organisms as Parts to Whole OrgansGroups of similarly functioning tissues.
9Examining Organisms as Parts to Whole Organ SystemsGroups of organs working together to perform specific functions.
10Examining Organisms as Parts to Whole Groups of interacting organ systems.
