Provide transfer of Oxygen form air to blood Inhaled21 Exhaled16 Provide transfer of carbon dioxide out What is the Respiration It is the act of breathing through inhalation inspiration and exhalation. 4 distinct events. Pulmonary ventilation. : air is moved in and out of the lungs. External respiration. : gas exchange between blood and alveoli. Respiratory gas transport. : CV system transports oxygen and carbon dioxide between lungs & tissues (discussed in Blood chapter). Breathing.

The 4 stages of Respiration:. The respiratory system uses many parts for breathing in oxygen . and releasing . carbon dioxide. .. These include the nose, the trachea, and the lungs. . First, air . enters through . the nose and mouth. The Layout of the . R. espiratory Organs. Breathing. Before Exercise. After intense exercise. Breathing is regular. Breaths have less volume. Enough oxygen is being provided to the muscles. Breathing is frantic. Created by A. Berryhill and D. Cashion. HS1/Spring 2016. Guess The Fib. 1. . The trachea is AKA the windpipe.. 2.

Includes respiratory bronchioles, alveolar ducts, alveolar sacs, and alveoli. Only places where gas exchange occurs. Video: What do the lungs do?. Mammalian Respiration. Respiration is made up of 4 parts:. Breathing – inspiration (inhalation) and expiration (exhalation). External Respiration – gas exchange between air and blood.

Major Function 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. Nose and Nasal Cavity. . Lined with membrane that produce mucus. . Nasal Septum = . divider in the center of the nose. . Turbnates. = . three long, bony projections. Pharynx = . throat. . Nasophyarynx. Provide oxygen to tissues. Remove carbon dioxide from tissues. Divided into. Pulmonary ventilation . inflow and out flow of air between atmosphere and lungs. Exchange . of oxygen and carbon dioxide between lungs and blood. 1. Pulmonary ventilation. = exchange of gases between lungs and atmosphere.. 2. External respiration. = exchange of gases between alveoli and pulmonary capillaries.. 3. Internal respiration. = exchange of gases between systemic capillaries and tissue cells.. MrT says…. I . pity the fool who . thinks . breathing. is . respiration.. . Breathing.
