• Systemic Anatomy

• Organization of the Body Parts

  1. All substances, including body parts, are composed of chemicals made up of submicroscopic particles called atoms

  2. Atoms join to form molecules, which can in turn join to form macromolecules

  3. For example, molecules called amino acids join to form a macromolecule called protein, which makes up the bulk of muscles
• Cells


  • Basic units of all living things
• Organelles


  • Tiny structures within cells that perform cellular functions
  • For example, the nucleus is especially concerned with cell reproduction; the mitochondrion supplies the cell with energy
• Tissues


  • Composed of similar types of cells and perform a specific function
• Organs


  • Composed of several types of tissues and perform a particular function within the organ system
  • For example, the stomach is an organ that is part of the digestive system
• Organs within the body systems

  Contribute to the overall function of the system
• All of the body systems together make up an organism, such as human beings
• Human beings are complex animals, but this complexity can be broken down and studied at ever simpler levels
