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.
Normal Urinary Output. The normal range for an adult urinary output is between 400 to 2,000 mL of urine daily -- with a normal fluid intake of about 2 liters per day. Values for normal urinary output may vary slightly between laboratories.A urine output of 500 mL per day is generally considered adequate for normal function.Factors other than kidney disease that can influence how much you urinate in a day include how much water you consume, the amount of fluid lost in perspiration, your caffeine and alcohol intake and any medications you've taken. urine output of 500 mL per day is generally considered adequate for normal function.
