The captured Africans were held in forts, sometimes called 'slave castles', along the coast. They remained there for months until finally leaving their homeland for an unknown destination on board European merchant ships, including those of the British Royal African Company.
Key Points. 1  The majority of fluid output occurs from urination. Some fluid is lost through perspiration (part of the body's temperature control mechanism) and as water vapor in expired air. 2  The body's homeostatic control mechanisms ensure that a balance between fluid gain and fluid loss is maintained.
Best Answer: The digestive tract and the urinary systems are principally the important players in maintaining water and electrolyte balance within the body. We take water in by mouth in food and drink, along with electrolytes. We excrete water through urine and feces. Also, a significant amount of water is lost through insensible losses by sweating and breathing. While sweating and breathing do shed water, it's the kidneys that are most responsible for ridding the body of water.
