Effects of hyperventilation on CO2 and pH levels Alidrin Armandico Physiology Lab 142 Egle Ortega Aprill 25‚ 2014 Abstract The aim of this experiment was to analyze how pH and carbon dioxide (CO2) levels in the blood change during hyperventilation and how the renal system compensates for this condition. Hyperventilation decreases CO2‚ increases pH‚ and lowers H+ levels which then results to respiratory alkalosis. In the experiment‚ we used the PhysioEx 8.0 software to simulate hyperventilation

Monica Mahmoudi 02072798 Bandaruk Mon-Wed 12:45 PH Balance in the Human Body As we all know every solution is either acid or alkaline. Alkaline is often called base. These solutions can be anything from body fluids‚ to fruits‚ vegetables‚ seawater‚ beverages you name it. Acid and alkaline is measured in pH. It starts as low as zero being very acidic and works its way up to fourteen being the most basic. The pH of our stomach is 2‚ obviously to digest food‚ wine is 3.5‚water is 7(neutral)‚ arterial

Lab Report 6: Respiratory Physiology Purpose: To describe the effects of carbon dioxide concentration on blood pH. Hypothesis: If the blood CO2 levels increase‚ the pH will decrease. Materials and Procedures: Materials: Willing subject (someone complete the activities of the experiment) Timer (with a second hand) Glass Urinary and Salivary pH (litmus) paper Drinking straw Procedures: 1. Measure 2 ounces of water in a glass. Obtain the pH of the

Experiment 05 Water Hardness October 8th‚ 2013 The hardness of water was determined using the methods of titration‚ conductivity‚ and pH analysis. The mean and uncertainty of CaCO3 is 134±36.0 ppm. An error that could have potentially happened could be that the equivalence point was not correctly established causing inaccurate data. BACKGROUND: 1In hard water there is a high amount of mineral content present in the water. Most of the mineral content that is present
