Respiratory Volumes Activity 2: Measuring Normal Respiratory Volumes 1. Minute respiratory volume: 7‚500 ml 2. Judging from the trace you generated‚ inspiration took place over how many seconds? 2 seconds 3. Expiration took place over how many seconds? 2 seconds 4. Does the duration of inspiration or expiration vary during ERV or FVC? Yes Activity 3: Effect of Restricted Air Flow on Respiratory Volumes 5. How does this set of data compare to the data you recorded for Activity

Experiment 3: ANALYSIS OF UNKNOWN ACID SAMPLE USING TITRATION METHOD Date of Experiment: 4 September 2012 Introduction An acid-base titration is a procedure used in quantitative chemical analysis to determine the concentration of either an acid or a base. Titration is the slow addition of an acid (or a base) of known concentration from a burette (a narrow graduated cylinder) to a base (or an acid) of unknown concentration fin an Erlenmeyer

The Digestive system breaks down the ingested food into absorbable forms of nutrients and absorbs nutrients‚ ions and water from the external environment of the body. It is designed to maximize digestion and absorption. The functional structures of the digestive system are the passage‚ the glands like salivary glands‚ gastric glands‚ pancreatic‚ intestinal glands and liver. Also‚ the four layers of the digestive system are mucosa‚ submucosa‚ muscularis and serosa. The digestive system is regulated

Hoeung 1 Tiffany Hoeung Ms. Braceras Honors Earth Science 4 March 2015 How Does Slope Affect the Movement of a Glacier Purpose: The purpose of this lab was to find how slope would affect glacier’s movement‚ and whether the movement was at a constant rate or changed. Hypothesis: If the slope is more steep‚ then the glacier’s movements will be faster than a less steep slope. Materials: Flubber Glue Water Borax Long tray Timer Procedure: 1

The Catalase Lab Stephen Human Anatomy & Physiology 9/30/12 Problem- How do different environments affect the reactivity of catalase? Hypothesis- If more catalase is added then more oxygen (kPa) will be produced in a faster rate because there is more catalase to react upon. If less catalase is added then less oxygen (kPa) will be produced in a slower rate because there is less catalase to react upon. Variable- Independent- Amount of Catalase (Filter Paper) Dependent- Amount of

Microscope lab report Introduction Microscope is a tool used to enlarge images of small objects that are hard to study with bare eyes. The compound light microscope‚ which is going to be used in this lab activity‚ is an instrument with two lenses and various knobs to focus the image. In this lab‚ we will learn about the proper use and handling of the microscope. Objectives: •Demonstrate the appropriate procedures used while using the compound light microscope correctly. •Make and use a wet mount

Purpose: The purpose of this lab was to see how the changes in exercise intensity affect the rate of metabolism within the body. Methods: In this lab‚ indirect calorimetry was used to measure metabolic rate by calculating caloric expenditure by the measurements of oxygen consumption. The variables measured were the fraction of oxygen expired‚ the fraction of carbon dioxide expired‚ and the total volume of air inspired. This experiment required the participation of two volunteers. First‚ the variables

Engineering B45 Concrete Lab Report Introduction: Concrete is a mixture of sand and rock or similar inert material (aggregates) held together by a cementing material. Usually the cementing material is Portland cement‚ but sometimes binders such as asphalt or gypsum are used‚ in which case the concrete may be called asphaltic concrete or gypsum concrete. Properties of concrete are governed not only by the properties of its ingredients (cement‚ water‚ sand‚ and coarse aggregate) but also‚ to a great
