    • Cells
    • Tissues(epitheilia, connective, nervous, and muscle)
    • Organs
    • Organ system
  2. What does the epithilial tissue do?
    supports the body and connects its parts
  3. What does the conective tissue do?
    includes glands and tissues that cover interior and exterior body surfaces
  4. What does teh nervous tissue do?
    along with bones, enables the body to move
  5. What does the muscle tissue do?
    transmits nerve impulses through the body
  6. Circulatory system(4 things)
    brings oxygen, nutrients, and hormones to cells; fights infection; removes cell wastes; helps to regulate temperature
  7. Digestive system(3 things)
