Pulse and Blood Pressure Lab (after lesson) Objectives: 1. To allow students to formulate and test hypotheses. 2. To allow students to practice taking pulse and blood pressure. Teacher notes: 1. Briefly review of how to take a pulse and a blood pressure (if necessary) 2. Instruct students to pair off 3. Students will fill out the lab worksheet which will help guide them in the lab. Answers to the questions: Using what you know about pulse and blood pressure‚ form a hypothesis about what

1. 2. Introduction of blood bank management system Blood banks collect‚ store‚ and provide blood. Typically‚ these banks collect blood from voluntary blood donors. The banks then sort blood by type‚ check blood to make sure it is free of disease and then store it for future use. The main mission of a blood bank is to provide life-saving blood to hospitals and other health care facilities. Blood cannot be created by any means‚ it can only be collected from the Humans i.e. donors. Recruitment of

Part I: Pre-Lab Diffusion/Osmosis Pre-Lab Introduction: Dialysis tubing allows molecules to diffuse through microscopic pores in the tubing. Molecules that are smaller than the pores can diffuse through the dialysis membrane along the concentration gradients. Molecules that are larger than the pore size are prevented from crossing the dialysis membrane. Answer questions in complete sentences. For problems‚ show equations and work with units and appropriate significant figures. Part IA: In the following

synthetic blood samples through a process called blood typing. According to Fredrick H. Martin‚ PhD.‚ et.al‚ blood typing is a test that determines a person’s blood type by checking the blood for the presence or absence of specific glycoprotein called antigens found on the surface of the red blood cells. The two clinically relevant antigens are the A antigen and B antigen. The blood type is named based upon which antigen is present on the surface of its red blood cells. There are four blood types.

Aim: 1) To determine the effects of different salt concentration on the percentage of weight change in potato cubes 2) To determine the isotonic solution concentration for the potato Hypothesis: 1) If the concentration of the salt solution is higher than the concentration in the potato cubes‚ the percentage of weight change in potato cubes will be higher (positive). If the concentration of the salt solution is the same as the concentration in the cell‚ there will be no net movement of water through

The effect of different music styles on blood pressure Experiment by: Claire Mouser and Garrett Swearingen Written by: Claire Mouser Written: 3/13/14 Abstract: The purpose of this experiment was to inform teenagers about the effect different genres of music can have on your heart rate. The heart rates of teens are affected differently when they listen to rock versus classical music. The goal of this experiment was to find out whether teens heart rates would change while they listened

Plant Pigments and Photosynthesis Problem: We are going to separate and identify pigments and other molecules from cell extracts through a process called chromatography. We will also test the theory that light and chloroplasts are required for light reactions to occur. Background: Pigments are chemical compounds which reflect only certain wavelengths of visible light. This is what makes them seem colorful. Many things contain pigments including flowers‚ corals‚ and even skin. More important than

The cardiovascular system is an organ system that distributes blood to all parts of the body. The cardiovascular system is a very important system in your body because it is the body delivery system for circulation of blood‚ which is made up of blood‚ blood vessels‚ and the heart. Cardiovascular can be compared to the muscular pump equipped with one-way valves‚ also a system of large and small plumbing tube where the blood travels through. The circulatory system is important because it transport
