Respiratory System Mechanics Simulation Lab Activity 1: MRV __7500__ ml/min =500 tv x 15bmp Does expiratory reserve volume include tidal volume? Explain. Expiratory reserve volume (ERV) does not include tidal volume. Expiratory reserve volume is the amount of air that can be expelled after a normal tidal exhalation. This means that tidal volume is not included in the ERV measurement. Activity 2: FEV1‚ as % of VC Radius FEV1 Vital Capacity FEV1% 5.00 3541 4791 73.90 4.50

Measuring Normal Respiratory Volumes 1) Calculate the minute respiratory volume using the tidal volume and breaths per minute (pump rate). 2) Define the following terms: a. Respiration- The act of breathing

The Respiratory System STRUCTURAL PLAN Basic plan of respiratory system would be similar to an inverted tree if it were hollow; leaves of the tree would be comparable to alveoli‚ with the microscopic sacs enclosed by networks of capillaries (Figure 14-1) Passive transport process of diffusion is responsible for the exchange of gases that occur during respiration. RESPIRATORY TRACTS Upper respiratory tract—nose‚ pharynx‚ and larynx Lower respiratory tract—trachea‚ bronchial tree‚ and lungs

The Respiratory System is crucial to every human being. Without it‚ we would cease to live outside of the womb. Let us begin by taking a look at the structure of the respiratory system and how vital it is to life. During inhalation or exhalation air is pulled towards or away from the lungs‚ by several cavities‚ tubes‚ and openings. The organs of the respiratory system make sure that oxygen enters our bodies and carbon dioxide leaves our bodies. The respiratory tract is the path of air from the
