The human cardiovascular system consists of the heart‚ the blood‚ and a system of transporting vessels. A human heart has four chambers: a right and left atrium and a right and left ventricle. The fist-sized heart sits in its own sac (the pericardium) in the middle of the chest under the sternum. In most people‚ the apex of the heart points to the left. There are two circuits of simultaneous blood flow in humans: a pulmonary circuit and a systemic circuit. In the pulmonary circuit‚ the right

The purpose of this experiment was to determine the weight percentage of copper in brass. This was achieved by performing a redox titration known as iodometry. Copper‚ which was obtained from the brass‚ was used to react with iodide to produce iodine. Iodine was then titrated with thiosulfate. In this experiment‚ the amount of titrant dispensed correlates with the amount of copper; therefore‚ the amount of copper in brass was calculated by using the data recorded. In this experiment‚ the analyte

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 experiment was to become familiar with the electrocardiograph to help us determine the electrical activity of the heart. As well as‚ to observe how exercise and different body positions(conditions) can affect the activity of the heart. Introduction Trained professionals can look at the EKG tracing and determine if the heart is normal or if the heart is abnormal. “An ECG records the electrical activity of the heart. The heart produces tiny electrical impulses which spread

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
