  1. 4. transports food and liquid from the pharynx to the stomach. Located in the chest, it lies behind the windpipe
  2. 6. outer serous membrane layer that lines the internal surface of the thoracic cavity, to reduce friction during breathing, create a fluid-filled cavity for lung expansion, and provide structural support, with specific regions being sensitive to pain.
  3. 8. in the chest's center between the lungs, positioned behind the breastbone (sternum) and slightly to the left. Its primary function is to pump oxygen-rich blood throughout the body while maintaining blood pressure and returning deoxygenated blood to the lungs
  4. 10. A specialized organ of the immune and endocrine systems, located in the upper chest behind the breastbone, that primarily matures, trains, and selects T-lymphocytes (T-cells) to fight infections and disease.
  5. 12. The main, short, wide artery arising from the right ventricle that carries deoxygenated blood to the lungs for oxygenation
  6. 16. Located in the middle mediastinum of the chest, surrounding the heart and roots of the great vessels. It acts as a protective, lubricated covering that prevents friction, anchors the heart in the chest
  7. 19. is a distinct anatomical structure in the right lung that separates the right superior (upper) lobe from the right middle lobe aids in independent expansion of the lobes during respiration
  8. 20. protects vital organs (heart, lungs) and enables breathing by shifting volume, Located between the neck and abdomen
Down
  1. 1. Covers surface of lung, to reduce friction during respiration by secreting lubricating fluid and to protect the lungs.
  2. 2. Transport oxygenated blood from the left lung to the left atrium of the heart. Located at the hilum of the left lung and behind the heart
  3. 3. space between the visceral pleura, reduces friction during respiration via serous fluid and maintains negative pressure to allow lungs to expand with the chest wall
  4. 5. tiny, thin-walled airways located at the end of the respiratory bronchioles in the lungs. Their primary function is to serve as conducting passages, connecting respiratory bronchioles to alveolar sacs
  5. 7. between the ribs in the thoracic cavity, to stabilize the rib cage and facilitate breathing by expanding (external) or shrinking (internal) the thoracic cavity to assist with inhalation and forced expiration
  6. 9. Smallest, final generation of bronchioles located deep within the lungs, acting as the transition zone between the conductive airways and the gas-exchange surfaces
  7. 11. Central anterior of the chest, to protect vital organs—heart, lungs, and vessels—and to facilitate breathing by connecting the first seven ribs via cartilage
  8. 13. are tiny, balloon-like air sacs located at the end of the bronchioles, serve as the primary site of gas exchange, allowing oxygen to enter the bloodstream and carbon dioxide to be removed through exhalation
  9. 14. At the base of the chest, separating the thoracic cavity (lungs/heart) from the abdominal cavity. It is the primary muscle of respiration, contracting to flatten and draw air into the lungs, and relaxing to force air
  10. 15. Delivering air to the respiratory bronchioles
  11. 17. at the end of bronchioles in the lungs. Their primary function is to facilitate rapid, efficient gas exchange—transferring inhaled oxygen ( into the bloodstream and removing carbon dioxide for exhalation—acting as the essential functional unit of the respiratory system
  12. 18. Acts as the main conduit for air entering and leaving the lungs.
