d. Stomach
C
Fluid output normally occurs through four organs: the skin, lungs, GI tract, and kidneys Insensi-ble water loss is not visible; it is continuous and occurs through the skin and lungs. Output of insensible water also increases with fever. Visible perspiration (sweat) is secreted by the sweat glands. The GI tract plays a vital role in fluid balance. Approximately 3 to 6 L of fluid move into the GI tract daily and return again to the ECF. However, diarrhea causes a large fluid output from the GI tract. The kidneys are the major regulator of fluid output because they respond to hormones that influence urine production. When healthy people drink more water, they make a larger urine volume to maintain fluid balance. In patient situations, fluid loss occurs abnormally, such as through vomiting (stomach), wound drainage, and hemorrhage.
