• The respiratory system performs breathing and the exchange of oxygen and carbon dioxide, utilizing the nose, mouth, paranasal sinuses, pharynx, larynx, trachea, bronchi, lungs, and thoracic diaphragm.
• The circulatory system partners with the respiratory system to deliver oxygen from the lungs to tissues and remove carbon dioxide.
• The organs of the human respiratory system, excluding the alveoli, function to conduct air into the lungs, a process aided by the muscles of respiration, primarily the diaphragm and intercostal muscles.
• The respiratory system includes openings such as the nose and mouth, and internal organs such as the lungs.
• The respiratory system is composed of breathing passages, lungs, and muscles of respiration; it functions to obtain oxygen from the air for cellular metabolism and to return carbon dioxide, a waste product of metabolism, to the air.
• The respiratory system is composed of breathing passages, lungs, and muscles of respiration; it obtains oxygen for cellular metabolism and removes carbon dioxide waste.
• The human respiratory system facilitates breathing and oxygen intake, and includes the nose, throat, trachea, bronchi, and lungs.
• The respiratory system supports the immune system by filtering and humidifying air, using mucus to trap pathogens and cilia to sweep debris out of the lungs at a rate of approximately 1,000 beats per minute.
• Respiratory system organs, excluding the alveoli, function to conduct air into the lungs with the assistance of the diaphragm and intercostal muscles.
• The lungs are the major organ of the respiratory system.
• The Respiratory System removes carbon dioxide from the body and delivers oxygen to the blood; it consists of the nasal passage, trachea, and lungs.
• The respiratory system functions to bring air into the lungs to supply the blood with oxygen.
• The respiratory system consists of the nasal cavity, pharynx, larynx, trachea, bronchi, bronchioles, and lungs (alveoli).
