👉 Fluid, in the context of bodily functions, primarily refers to blood, but it can also include other bodily fluids like saliva, sweat, and mucus. The primary cause of fluid in the body is the balance between fluid intake and fluid loss. Fluid intake occurs through water consumption, food (especially fruits and vegetables), and other beverages. Fluid loss happens through various means such as sweating during exercise or physical activity, breathing out water vapor, urination, and bowel movements. When the body's fluid intake doesn't match its fluid loss, it results in dehydration or an excess of fluid, known as fluid overload. Maintaining this balance is crucial for proper bodily functions, including regulating body temperature, transporting nutrients and oxygen, and removing waste products.
