metal from is spinning and turbulence. Galvanic Corrosion: Galvanic corrosion (also called ’ dissimilar metal corrosion ’ or wrongly ’electrolysis ’) refers to corrosion damage induced when two dissimilar materials are coupled in a corrosive electrolyte. (corrosion-doctors.org) I have seen this in aluminum hand rails for walkway bridges. Usually this happens when a contractor forgets to put the rubber spacer between the aluminum and steel. The aluminum last only about a year before the hand rail

made up of water‚ it has many functions and is an important component of the blood. These functions consist of : Assisting in the transportation of the blood throughout the body. Helping to maintain the pH of the blood and also regulation of electrolytes in the body (http://www.ivy-rose.co.uk) The red blood cells or erythrocytes are the “most abundant cell in the blood‚ accounting for about 40-45% of its’ volume” (http://www.hematology.org). They are bright red in color due to its oxygen content

athlete and their performance. As potassium keeps your blood pressure regulated‚ niacin helps in maintaining good levels in your body by removing the toxins. Now‚ dairy products do not only supply the nine essential nutrients‚ but electrolytes and carbohydrates. The electrolytes found in dairy products replaces those found in sports drinks. In a study published in the journal Applied Physiology‚ researchers found that those who drank milk after training were capable of exercising longer in their upcoming

Fluids The amount of fluids in the body is extremely large. There are many different forms of fluid throughout the body‚ such as blood‚ urine‚ hormones‚ cerebral spinal fluid‚ water‚ albumin‚ and bile. The fluids that make up the body are required for homeostasis. There are many different functions of body fluids such as transporting nutrients‚ waste and gases‚ transforming food into energy and generate electrical activity to power body functions. Physiologic Fluid Compartments The major fluid

referred to as dehydration. Euvolamia is the term used to describe a state of normal body fluid (Welch 2010). Approximately 60 percent of a male’s body weight and 52 percent of a female’s body weight is fluid‚ which consists mostly of water and electrolytes. A reduction of only 5 percent in this fluid would result in a patient developing thirst and would be considered mild dehydration. 8-10 percent would cause hypertension‚ tachycardia‚ weak pulse‚ confusion and a decrease in urine output. 10-15 percent

Diet Analysis Proteins: After compiling data from my diet analysis‚ it became evident that my protein intake was within normal limits for my weight at 104% (97 grams) of the recommended range for me to lose weight. However‚ while being overweight‚ my calorie intake as a whole needs to be decreased in order to reach a healthy weight. Excess protein can lead to heart disease because a lot of it‚ at least in my diet‚ comes from saturated animal fats. These fats contribute to plaque buildup in the
