PPT-The Respiratory System Chapter 7

Key terms Having to do with the sinus Sinus Airfilled cavity within a bone that is lined with mucous membrane that makes mucus Functions of the sinuses Make the bones of the skull lighter Help produce sound by giving resonance to the voice. Respiratory System: . Intakes oxygen. Releases carbon dioxide waste. Circulatory system:. Transports gases in blood between lungs and cells. Respiratory system works with Cardiovascular system. Respiratory system anatomy. Mrs. Hasson. Ms. Golden. Mrs. Lattanzio. Mrs. . Hopkins. 7. th. Science. The Respiratory System. The purpose of the Respiratory System is to bring needed . Oxygen . to the cells and remove the waste product . Respiratory System. Air sac. air-filled spaces in the body. alveoli. very small air sacs; where air breathed in goes. Respiratory System. Bronchial tubes. two tubes at the end of the trachea, brings in air from trachea and helps clean lungs; one tube goes to right lung, one to left. Explain how the upper respiratory tract filters, moistens, and directs air.. Describe the composition, structure, and function of the lower respiratory system.. Describe how the mechanical action of breathing moves gases into and out of the lungs.. The main function of the . respiratory system. is to allow oxygen from the air to enter the blood and carbon dioxide from the blood to exit into the air.. Ventilation. , another term for breathing, includes both inspiration (inhalation) and expiration (exhalation).. Transports air into the lungs and facilitates the diffusion of oxygen into the blood stream. Receives carbon dioxide from the blood and exhales it. Organs of the Respiratory system. Slide 13.1. Copyright © 2003 Pearson Education, Inc. publishing as Benjamin Cummings. 7.1 Structures. Goals for this Chapter:. Explain how the upper respiratory tract filters, moistens, and directs air.. Describe the composition, structure, and function of the lower respiratory system.. . Learning Objectives. Define terms relating to the respiratory system. Describe the three functions of the respiratory system. Identify at least ten respiratory system structures and the function of each. How do we breathe?. What makes smoking so bad?. Why do we need oxygen?. The respiratory system works with the circulatory system in the following 4 areas of homeostatic functions:. Breathing: . exchange of air in and out of . Science 2017-2018. What You Need to Know… . Describe. the functions of the respiratory system. Explain . how oxygen and carbon dioxide are exchanged in the lungs and in tissues. Identify. the pathway of air in and out of the lungs. 1. R. espiration. 2. . Smell. 3. . Filtration. /defense. 4. . Sound . & speech production. 5. E. liminate . waste. Respiratory System. B.

Human cells obtain that energy through aerobic mechanisms that require oxygen & produce carbon dioxide.. Humans respiratory exchange surfaces are confined to the inside of the lungs (in a warm, moist, protected environment) under these conditions, diffusion can occur between the air and blood.. By. Dr.. K. . Usha. Rani . DNR. College . Respiratory system. . The avian respiratory system is different from that of other vertebrates. Birds having relatively small lungs plus nine air sacs that play an important role in respiration .
