After completing chapter 28, you will be able to: List the pathways and organs of the lymphatic system and give their locations; define lymph and tell how it is circulated in the body; define the terms infection, pathogen, and antigen; list and describe the nonspecific body defense mechanisms; explain the signs and causes of inflammation. | 29 The Respiratory System Learning Outcomes (cont.) Describe the structure and function of each organ in the respiratory system. Describe the events involved in the inspiration and expiration of air. Explain how oxygen and carbon dioxide are transported in the blood. Learning Outcomes (cont.) Compare various respiratory volumes and tell how they are used to diagnose respiratory problems. Describe the causes, signs and symptoms, and treatments of various diseases and disorders of the respiratory system. Introduction Function Move air in and out of lungs Delivers oxygen (O2) Removes carbon dioxide (CO2) External respiration – in the lungs Internal respiration – within the hemoglobin O2 O2 O2 CO2 CO2 CO2 Lungs Learning Outcomes: Describe the structure and function of each organ in the respiratory system. The function of the respiratory system is called ventilation, respiration, or breathing. Delivers oxygen to body cells via the bloodstream. | 29 The Respiratory System Learning Outcomes (cont.)

The function of the respiratory system is called ventilation, respiration, or breathing. Delivers oxygen to body cells via the bloodstream. Removes carbon dioxide from the blood. External respiration – the exchange of oxygen and carbon dioxide in the lungs Internal respiration – the exchange of oxygen and carbon dioxide within the hemoglobin of the RBCs. Organs of the Respiratory System Nose Pharynx Larynx Trachea Bronchial tree Lungs Learning Outcomes: Describe the structure and function of each organ in the respiratory system. Nose Made of bones and cartilage and the skin covering them. Openings are the nostrils, or nares. The hairs of the nostrils prevent large particles from entering the nose. Organs of the Respiratory System (cont.) Nasal Cavity Nasal septum Nasal conchae Mucous membrane warms and moistens the air Cilia eliminate particles To Diagram Learning Outcomes: Describe the structure and function of each organ in the respiratory system. The nasal cavity The hollow space behind the nose. Divided by the nasal septum. Nasal conchae Extend from the lateral walls of the nasal cavity. Support the .
