Document Summary
Physiology is study of function, while anatomy is the study of structure. How a molecule is shaped determines the job that is does. levels of physiological organization. Cells (neurons, epithelial cells: nothing smaller than a cell is considered to be living, viruses are between living and non-living, considered non-living because it is not a cell. It is an amino acid rapped in a protein coat. Tissue (nervous tissue, muscle tissue: cells working together. Neurons/nervous tissue: motor neurons, cortical interneurons, etc, specialized for sending and receiving information. Epithelial cells/epithelial tissue (intestinal epithelial cells, etc. : found on organs, glands, and lining body cavities, allows for exchange between outside of body and inside. Connective tissue cells (bone cells, blood cells, fat cells, etc: characterized by very few cells and lots of extracellular materials, most diverse type of tissue, tendons, ligaments, and cartilage. If looked at under a microscope, there are a lot less cells and a lot more fluids and proteins.
