you might need to replace some of the salts that your body loses through sweat. These salts‚ or electrolytes‚ are found in most sports drinks. What are the advantages of a sports drink over water? Water will provide the liquid you need to avoid dehydration‚ but does not have electrolytes. Anelectrolyte is a substance that will dissociate into ions in a solution. The ions in the solution give it the capacity to conduct electricity. Electrolytes‚ such as sodium and potassium‚ are present in sweat‚ and

Introduction: Diseases can be communicable or non-communicable. Communicable diseases are caused by infectious microorganisms which are pathogens. The aim of this passage is to discuss various types of microorganisms that cause disease. Microorganisms are simple organisms that are unicellular or live in colonies. The group contains bacteria‚ virus‚ algae‚ fungi‚ protozoa. They can be divided into pathogenic and non-pathogenic. In this passage pathogenic microorganisms that cause diseases are

The peak incidence (the rate of influence of something‚ especially of something unwanted) of kwashiorkor is between the age of 9 months and 2 years (Vlok‚ 1986). Kwashiorkor is not differentiated between genders. Kwashiorkor is a form of severe protein - energy malnutrition which means there are usually enough calorie intakes but not enough protein consumption (Unknown‚ Kwashiorkor‚ 2015). It is the most common widespread nutritional disorder in developing countries (Cafasso‚ 2012). Every cell in

For humans they must maintain an internal temperature of 36.7OC (this is the set point for the internal environment of a human to remain at homeostasis state). Components of a homeostatic system is a receptor‚ a control centre and an effector; The receptor that detects the change from a stimuli (when it becomes

too much acid is called acidosis. Acidosis happens when the kidneys and the lungs could not keep up your body’s pH in balance. Many of the body’s processes produce acid. For example‚ the lungs and the kidneys can usually compensate for slightly pH imbalances; however the problems with lungs and kidneys can causes to excess acid in our body. The acidity of the blood in your body is determined by PH. A lower PH shows that your blood is more acidic and higher PH shows that your blood is more alkaline (base)

These risks include high blood pressure‚ ventricular hypertrophy and heart failure‚ osteoporosis‚ kidney stones‚ dehydration‚ breathing difficulties‚ duodenal and gastric ulcers‚ electrolyte and hormonal imbalance.
