PPT-How the Lungs Work Alveoli

Air Sacs Resemble bunches of grapes Make up bulk of lungs Respiratory Zone Includes respiratory bronchioles alveolar ducts alveolar sacs and alveoli Only places where gas exchange occurs. 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. Disease of The Lungs. Causes. By breathing in tiny fibers of asbestos, a heart resistant material that used to be common in insulation, vinyl floor tiles, cement, brake lining, and other products. People who have had a lot of exposure to asbestos at home, or work, can get asbestosis. It is environmental and is not contagious. . lung disease. 4.1 Structure of the human gas-exchange system. Remember these guys?. Breathing - brainpop.swf. Learning objectives. Student should understand the following:. The gross structure and function of the human gas exchange system limited to the alveoli, bronchioles, bronchi, trachea and lungs.. http://youtu.be/HiT621PrrO0. To exchange oxygen and carbon dioxide between the blood, the air and tissues.. Function of the Respiratory System. The Flow of Air. Nose or mouth. Pharynx. Larynx. Trachea - . Put them in the correct order . Terminal bronchioles . Secondary bronchi. Alveoli, alveolar ducts and alveolar air sacs.. Right and left primary bronchi. Tertiary bronchi. Trachea. Nose . The structure of the thorax. PowerPoint. ®. Lecture Slide Presentation by . Robert J. Sullivan. , Marist College. EXCHANGE OF GASES. RESPIRATORY SYSTEM. The human respiratory system allows one to obtain oxygen, eliminate carbon dioxide. . and Disorders. Gas Exchange. Gas exchange occurs in the alveoli due to the difference in the partial pressures of oxygen and carbon dioxide in the capillary blood and the alveoli.. Since the concentration of oxygen is greater in the alveoli, it diffuses into the capillary blood.. . . ystic. . Fibrosis. . . ronchitis. . – Chronic. . sthma. . . . ronchiectasis. . . mphysema. Chronic . Obstructive Pulmonary Disease. Smoking. #1 cause of COPD. Increased mucous production. What is gas exchange?. The process all organisms undergo in which they absorb one gas from the environment and release a different one. . In human gas exchange… . -absorb oxygen for cell respiration and release carbon dioxide as waste. Presented by Toni Davis and Niamh McDonald. Function of the Respiratory System. What Does The Respiratory System Do?. The respiratory system takes in oxygen to circulate around the body for many uses such as creating ATP, supplying systems with oxygen for smelling and speaking.. Nose. Nose. Function: . Inhales Oxygen (. O. 2. ) . and Exhales . . . Carbon . Dioxide (. CO. 2. ). Uses nose hair (Cilia) to filter dust and germs from entering the lungs. Moistens the air. Warms air . The Conducting Zone. Nose. Only external visible part of the respiratory system. Air enters the nose by passing through the nostrils. The interior of the nose consists of the nasal cavity which is divided by the nasal septum. Do Now activity:. Identify some of the organs involved in the gas exchange system in the human body.. Discuss with your partner what function of some of these organs might be within this system. Explain why organisms need an efficient gas-exchange system. Functions of Respiratory System . Provides enormous Surface area for . gas exchange. . between alveoli and circulating blood.. Helps . regulate pH. of body fluids.. Permits vocal . sounds. .. External nares.
