PPT-Chapter 23 – Anatomy of the Respiratory System

Dr Kim Wilson Introduction to the Respiratory System FUNCTIONS 1 Providing an extensive surface area for gas exchange between air and circulating blood 2 Moving air to and from the exchange surfaces of the lungs. 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).. Animal Anatomy and Physiology. At the completion of this unit, students will be able to:. Describe the organs, function, and common diseases associated with the . skeletal. and . muscular. systems. 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.

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. 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. 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 . Form and structure of the body and its parts.
