1.) When you forcefully exhale your entire expiratory reserve volume‚ any air remaining in your lungs is called the residual volume (RV). Why is it impossible to further exhale the RV (that is‚ where is this air volume trapped‚ and why is it trapped?) This "dead space" of air needs to stay in your lungs constantly; otherwise the lung will completely deflate. If the lung has every bit of air sucked out of it‚ it will collapse and need to be re-inflated. 2.) How do you measure a person’s

chemical stimulation. I would want to see what different chemicals would cause an action potential versus chemicals that would not cause an action potential. And‚ whether different amounts of a particular chemical would affect the action potential. 7. Why does the addition of sodium chloride elicit an action potential? Hint: Think about the sodium permeability of the neuron (Figure 3.2e). The addition of sodium chloride will increase the sodium ion concentration outside the cell membrane. The sodium

reliability. This will ensure that all data collected and measured in the lab are accurate and reliable as well. The process of testing an instrument’s accuracy is known as calibration. The purpose of this lab was to calibrate a variety of equipment frequently utilized in the Exercise Physiology lab and to become familiar with the operation of the calibrated equipment (Lab manual). The equipment calibrated in the exercise physiology lab was the speed of the Parvo treadmill‚ the incline of the Cosmed treadmill

Exercise 7 Review Sheet Definitions/Explanations: Respiration: The entire process of gas exchange in the body; it includes each of the following: 1. Pulmonary Ventilation (AKA breathing): The follow of air into and out of the lungs. The result of muscle contraction of the diaphragm. Ventilation consists of two parts: a. Inspiration: The process that occurs when atmospheric gas is drawn into the lungs by way of contraction of the diaphragm which causes expansion of the thoracic

Homeostasis and Exercise Lab Living Environment/Lab #7 Ms. Iadanza December 2012 Problem: How does exercise affect a person’s heart rate‚ breathing rate‚ and perspiration level? Background Information: Homeostasis is the maintaining of a balanced condition in the body despite changing external conditions or demands on the body. The circulatory system works with the respiratory system in order to deliver nutrients to the body’s cells. The respiratory system is made of the mouth and

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
