  1. Introduction to the Human Body Lesson 1 Anatomy and Physiology

  2. Anatomy and Physiology Defined • Anatomy is the study of the body structures and the relationships between those structures. • Physiology is the study of body function, how the various structures work and function together

  3. Levels of Structural Organization • Levels of organization begin with the smallest and least complex and grow to become larger and more complex. • First level: Chemical • Composed of atoms, which make up molecules such as amino acids, nucleic acids, and glucose. • Second level: Cellular • Composed of cells made from molecules. Cells are the basic structural and functional units of the body.

  4. Third level: Tissues • Tissues are composed of groups of cells and materials that hold cells. A tissue can be composed of only one type of cell or can be composed of many types of cells. • Fourth level: Organs • Organs are composed of groups of tissues. Each organ has a specific function and usually have recognizable shapes.

  5. Fifth level: Systems • Systems consist of related organs with common functions. The organs work together for the benefit of the organism. Some organs are part of more than one system. • Sixth level: Organism • The most complex level of organization. The organismal level is reached when all of the body parts and system work together to maintain life.

  6. Diagnostic Techniques: Noninvasive • Inspection • The body is observed for deviations from the norm. • Palpation • Body surfaces are felt by the hands.

  7. Auscultation • Body sounds are listened to using a stethoscope to evaluate the functioning of certain organs. • Percussion • Body surface is tapped with the fingertip and the resulting echo analyzed. It can also be used to provide information about underlying structures.

  8. The Eleven Body Systems • Integumentary • Composition: • Function: • Skeletal • Composition: • Function: • Muscular • Composition: • Function:

  9. Nervous • Composition: • Function: • Endocrine • Composition: • Function: • Lymphatic • Composition: • Function:

  10. Cardiovascular • Composition: • Function: • Respiratory • Composition: • Function: • Digestive • Composition: • Function:

  11. Urinary or Excretory • Composition: • Function: • Reproductive • Composition • Function
