Review on the Respiratory System Anatomy & Physiology Name Part 1 Directions: Match each of the organs to the statements that describe them. (A) nasal cavity F 2 large organs where gas exchange occurs (B) pharynx formed by the division of the trachea (C) larynx contains cilia that sweep mucus upward (D) trachea passageway for food and air (E) primary bronchi tiny air sacs that allow gas exchange (F) lungs Cincludes thyroid cartilage, glottis and vocal cords (G) alveoli A particles are trapped on mucus-coated conchae Part 2 Directions: Match each term with its correct description. (A) Pulmonary Ventilation gas exchange between blood and tissue cells. (B) External Respiration moving oxygen and through the bloodstream (C) Gas Transport also known as breathing (D) Internal Respiration B gas exchange between blood and alveoli Part 3 Directions: Answer the questions with 1-3 complete sentences. 1) Explain what role the diaphragm has in controlling inspiration. Be sure to mention changes in thoracic volume and air pressure in your answer. As diaphragm contracts it moves & increasing the Volume in the thoracic cavity and decreasing the pressure. Air will filow from high to low pressure So our will enter lungs. 2) Explain what role the diaphragm has in controlling expiration. Be sure to mention changes in thoracic volume and air pressure in your answer. When diaphragm relaxes it moves To cdecreasing the velune of the thoracic cavity ouned increasing pressure. This forces cur cut Part 4 Directions: Match each disease/disorder with its correct description. (A) Pneumonia CInflammation of Tertiary Bronchi (B) emphysema B Overinflated alveoli (C) bronchitis E Chronically inflamed, hypersensitive bronchi (D) cystic fibrosis D A lethal genetic disease (E) asthma A Fluid filled alveoli from infection (F) Sleep Apnea Breathing frequently stops during sleep Part 5 Directions: Answer the questions with 1-3 complete sentences. 1) How is air warmed as it passes through the nasal cavities? Conchae Spin air-Blood from capillaries. is warmer ~> heats air 2) How does smoking affect the cilia inside the trachea? What affect does this have on a patient's breathing? stuns them, so they dont work (www mavement) Tabacco products make it to alveoli which will became clogged and stop working 3) What is the function of the pulmonary pleura and pleural fluid? Protection from friction 4) Why is it detrimental to have excess mucus in the airways and lungs (what can result)? Blockage of air movement and gas transport. Oz and cox exchange 5) Explain why it is not possible to stop breathing voluntarily. Autonomic Nervous system. A
