Physio-EX Blood Analysis: Computer Simulation Introduction In this lab five blood tests will be performed: hematocrit determination‚ erythrocyte sedimentation rate‚ hemoglobin determination‚ blood typing‚ and total cholesterol determination. A “hematocrit refers to the percentage of red blood cells (RBC’s) in a sample of whole blood. Since the function of red blood cells is the transport of oxygen to the cells of the body‚ the higher the hematocrit‚ the more red blood cells are available to carry

Sodium chloride‚ urea‚ glucose‚ albumin Activity 2 5. Explain one way in which facilitated diffusion is the same as simple diffusion and one way in which it differs. a. Simple diffusion moves molecules from an area of higher concentration to an area of lower concentration without an input of energy. Facilitated

Review Sheet Results (1) 1. List the hematocrits for the healthy male (sample 1) and female (sample 2) living in Boston (at sea level) and indicate whether they are normal or whether they indicate anemia or polycythemia. 1. The hematocrit value for the healthy male: 48 2. The hematocrit value for the healthy female: 44 Both values are normal because they are between the normal ranges: for males between 42-52% and for females between 42-47%. 2. Describe the difference between the hematocrits

Cardiovascular Physiology and Blood Pressure July 27‚ 2009 BY 409L - LW Blake Perry Lab Partners: Jennifer Rastegar and John Riopka Abstract This experiment was designed to observe a baseline heart rate and blood pressure and to examine various modifications of the two. This experiment utilized both the BiopacPro and PhysioEx computer programs. The PhysioEx program was used to simulate a heart rate and modifications to it. The BiopacPro program was used to monitor a volunteer’s blood pressure;

lower than the hemoglobin levels of a normal‚ healthy individual? You correctly answered: c. Because hemoglobin resides in RBCs‚ you would anticipate a low hematocrit level to coincide with a low hemoglobin level.
