  3. 6. A tissue that connects muscule to bone
  4. 7. A dome-shaped muscle at the base of the lungs that helps with inhalation of air with oxygen and exhalation of air with carbon dioxide
  5. 10. A tissue that provides padding between bones
  6. 14. Muscle tissue found only in the heart that contracts to move blood through the body
  7. 15. The process by which the body breaks down food into small nutrient molecules
  8. 17. A component of blood that sticks together to form clots to stop bleeding
  9. 18. The organ system in the human body that includes the lungs and functions to bring in oxygen and remove carbon dioxide from the body
  10. 20. The process by which wastes are removed from the body (Solid waste leaves by the digestive system; liquid waste by the excretory system.)
  11. 21. The organ system in the human body that includes the heart and blood vessels and functions to move blood through the body

  2. 2. Large tubes that carry blood away from the heart
  3. 4. Substances in food that provide the raw materials and energy the body needs to carry out its essential processes

  9. 16. Liquid waste released through pores in the skin to help cool the body as it evaporates
  10. 18. A component of blood that picks up oxygen in the lungs and delivers it to cells in the body AND picks up carbon dioxide from the cells to carry to the lungs for excretion
