    Study Notes

    Anatomy and Physiology

    • Anatomy and physiology are two branches of science that provide the foundation for understanding the body's parts and functions.
    • Anatomy is the study of the body's structure, including its size, shape, composition, and coloration.
    • Physiology is the science of body functions, dealing with how the body parts work.

    Levels of Structural Organization

    • The human body is organized into six levels of increasing complexity: chemical, cellular, tissue, organ, organ system, and organism.
    • The chemical level includes atoms, molecules, and chemicals that make up the body.
    • The cellular level consists of cells, the basic structural and functional units of an organism.
    • The tissue level is a group of cells with similar structure and function, with four basic types: epithelial, connective, muscular, and nervous tissues.
    • The organ level consists of different types of tissues joined together to accomplish specific functions.
    • The organ system level is a group of organs that contribute to a particular function.
    • The organismal level is the entire human body functioning together.

    Chemical Level

    • Atoms and molecules make up the body's chemicals, which are divided into inorganic and organic categories.
    • Inorganic chemicals are usually simple molecules made of one or two elements, excluding carbon.
    • Organic chemicals are complex molecules containing carbon and hydrogen, including carbohydrates, fats, proteins, and amino acids.
    • Examples of important molecules in the body include DNA and glucose.

    Cellular Level

    • Cells are the basic structural and functional units of an organism, composed of chemicals.
    • There are many different types of human cells, including muscle cells, nerve cells, and epithelial cells.
    • Each cell carries out specific chemical reactions and has similarities with other cells.

    Tissue Level

    • A tissue is a group of cells with similar structure and function.
    • The four basic types of tissues are epithelial, connective, muscular, and nervous tissues.
    • Epithelial tissues cover body surfaces, line hollow organs and cavities, and form glands.
    • Connective tissues connect, support, and protect body organs while distributing blood vessels to other tissues.
    • Muscle tissues are specialized for contraction, generating movement and heat.
    • Nerve tissues generate and transmit electrochemical impulses that regulate body functions.

    Organ Level

    • An organ is a group of tissues precisely arranged to accomplish specific functions.
    • Examples of organs include the kidneys, stomach, liver, and heart.

    Organ Systems Level

    • An organ system is a group of organs that contribute to a particular function.
    • Examples of organ systems include the digestive system, which breaks down and absorbs food, and the urinary system, which forms and eliminates urine.
    • Sometimes an organ is part of more than one system.

    Branches of Anatomy and Physiology

    • Branches of anatomy include embryology, developmental biology, cell biology, histology, pathological anatomy, gross anatomy, systemic anatomy, regional anatomy, surface anatomy, and imaging anatomy.
    • Branches of physiology include neurophysiology, endocrinology, cardiovascular physiology, immunology, respiratory physiology, and renal physiology.
