Integumentary System
- Nasal hairs and mucus prevent
 dust and other foreign material from
 damaging respiratory passageways
 (p. 536)
Skeletal System
- The lungs are protected by the rib
 cage, and bones of the rib cage
 serve as levers for the action of
 respiratory muscles (p. 541)
- Red blood cells, needed for oxygen
 transport, are produced in the bone
 marrow (p. 409)
- The respiratory system provides
 all organs, including the bones,
 with oxygen and eliminates carbon
 dioxide (p. 533)
Muscular System
- Contractions of skeletal muscles
 are needed for ventilation (p. 541)
- Muscles consume large amounts of
 oxygen and produce large amounts
 of carbon dioxide during exercise
 (p. 378)
Nervous System
- The nervous system regulates the
 rate and depth of breathing (p. 553)
- Autonomic nerves regulate blood
 flow, and hence the delivery of
 blood to tissues for gas exchange
 (p. 466)
Endocrine System
- Epinephrine dilates bronchioles,
 reducing airway resistance (p. 545)
- Thyroxine and epinephrine
 stimulate the rate of cell respiration
 (p. 675)
Circulatory System
- The heart and arterial system
 delivers oxygen from the lungs
 to the body tissues, and veins
 transport carbon dioxide from the
 body tissues to the lungs (p. 405)
- Blood capillaries allow gas
 exchange for cell respiration in the
 tissues and lungs (p. 433)
Immune System
- The immune system protects
 against infections that could
 damage the respiratory system
 (p. 494)
- Alveolar macrophages and the
 action of cilia in the airways help to
 protect the lungs from infection
 (p. 536)
Urinary System
- The kidneys regulate the volume
 and electrolyte balance of the
 blood (p. 582)
- The kidneys participate with the
 lungs in the regulation of blood pH
 (p. 608)
Digestive System
- The GI tract provides nutrients to
 be used by cells of the lungs and
 other organs (p. 620)
- The respiratory system provides
 oxygen for cell respiration of
 glucose and other nutrients brought
 into the blood by the digestive
 system (p. 111)
Reproductive System
- The lungs provide oxygen for cell
 respiration of reproductive organs
 and eliminate carbon dioxide
 produced by these organs (p. 533)
- Changes in breathing and cell
 respiration occur during sexual
 arousal (p. 712)
