  1. 4. Phagocytes inside alveoli, alpha 1-antitrypsin and genetic factors are causes of ______
  2. 8. tiny, air-filled sacs located in the lungs of the human body. They are the primary sites of gas exchange in the respiratory system, facilitating the exchange of oxygen and carbon dioxide between the air we breathe and our bloodstream.
  3. 9. small, narrow air passages within the human respiratory system that are part of the lower airway. They are located in the lungs and are responsible for further branching and distributing the air that enters the respiratory system.
  4. 10. pair of vital organs in the human body that form the central component of the respiratory system. They are responsible for the exchange of oxygen and carbon dioxide between the bloodstream and the external environment, allowing the body to obtain oxygen for cellular respiration and remove carbon dioxide, a waste product of metabolism.
  5. 12. _______ are the large, branching airways within the human respiratory system that carry air from the trachea (windpipe) into the lungs
  6. 13. the process by which oxygen (O2) is taken in from the external environment and carbon dioxide (CO2) is expelled from the body.
  7. 14. pressure The specific pressure exerted by a particular mixture of gasses is called _____
  8. 16. Gas exchange is _____ when the area of diffusion is larger and the path of diffusion is shorter
  9. 18. the process of moving air in and out of the lungs, facilitating the exchange of gasses (oxygen and carbon dioxide) between the respiratory system and the external environment.

  1. 1. When carbon dioxide ______, blood pH level decreases.
  2. 2. ________ has 4 subunits
  3. 3. commonly known as the voice box, is a complex structure located in the throat of the human body. It plays several crucial roles in respiration .
  4. 5. a muscular tube-like structure located in the throat, behind the nose and mouth, and in front of the esophagus and trachea. Functions include part of the digestive and respiratory system.
  5. 6. referred to as the windpipe, is a vital part of the human respiratory system. It is a tubular structure that connects the larynx to the bronchi, which leads to the lungs.
  6. 7. a complex biochemical process that occurs within the cells of the human body. It is the primary means by which cells obtain energy (in the form of adenosine triphosphate or ATP) from organic molecules, typically glucose, and other fuel sources.
  7. 11. Lung ______ is caused by smoking, passive smoking, air pollution intake, radon gas and asbestos
  8. 15. large, dome-shaped muscle located at the base of the thoracic cavity in the human body. It separates the chest cavity (thoracic cavity) from the abdominal cavity
  9. 17. When lungs expand pressure _____
