The document summarizes the key components and functions of the respiratory system. It describes the basic functions of supplying oxygen to the body and removing carbon dioxide. It outlines the four main processes of respiration and identifies the major respiratory organs like the nose, pharynx, larynx, trachea, bronchi, lungs and alveoli. It provides details on the anatomy and roles of specific structures like the nose, larynx, trachea, bronchi and lungs. It also discusses aging effects and some respiratory disorders.

- 16. Blood Supply and Innervation of the Lungs Pulmonary arteries Deliver oxygen-poor blood to the lungs Pulmonary veins Carry oxygenated blood to the heart Innervation Sympathetic, parasympathetic, and visceral sensory fibers Parasympathetic – constrict airways Sympathetic – dilate airways Copyright © 2008 Pearson Education, Inc., publishing as Benjamin Cummings

Disorders of Respiratory Structures Cystic fibrosis (CF) – inherited disease Exocrine gland function is disrupted Respiratory system affected by Oversecretion of viscous mucus Epistaxis – nosebleed Epiglottitis – inflammation and swelling of the epiglottis Copyright © 2008 Pearson Education, Inc., publishing as Benjamin Cummings
- 18. Aging of the Respiratory System Number of glands in the nasal mucosa declines Nose dries Produces thickened mucus Thoracic wall becomes more rigid Lungs lose elasticity Oxygen levels in the blood may fall Copyright © 2008 Pearson Education, Inc., publishing as Benjamin Cummings
