Interaction With Other Body Systems ENDOCRINE: Converting enzymes in lung convert angiotensin I to angiotensin II. Epinephrine and norepinephrine increase respiratory rate and dilate airways. URINARY GU system works with respiratory system to eliminate wastes and maintain acid-base balance. LYMPHATIC Alveolar macrophages trap microorganisms and other foreign substances. Foreign material removed by cilia or lymphatic system. Tonsils and adenoids protect upper airways from infection, but also may become enlarged and obstruct breathing.
INTEGUMENTARYProtects structures of upper respiratory tract. Nasal hair filters air. Skin color reflects oxygenation.NEUROLOGICALMedulla is respiratory center. Chemoreceptors respond to changes in carbon dioxide, oxygen and hydrogen ions by affecting rateand depth of respirations.CARDIOVASCULARCardiovascular system transports oxygen and carbon dioxide between lungs and peripheral tissue. Activation of angiotensin by lungs important in B/P regulation. Peripheral chemoreceptors in aortic arch and carotid arteries respond to oxygen, carbon dioxide and hydrogen ion concentrations.
DIGESTIVEAbdominal muscles aid with respirations. GItract provides nutrients to respiratory system.MUSCULARDiaphragm, chest and abdominal musclesneeded for breathing. Accessory musclesused when oxygen demands are increased, aswith strenuous exercise.REPRODUCTIVESexual activity increases oxygen demands.Pregnancy affects oxygen demands andbreathing.SKELETALRibs provide protective framework for lungs.
