What do sudoriferous glands primarily excrete?

• A. Oils and dirt
• B. Water and lactic acid
• C. Salt and potassium
• D. Protein and enzymes

Answer: (B)

Sudoriferous glands, commonly known as sweat glands, primarily excrete water and lactic acid as part of the body's thermoregulation and waste elimination processes. These glands are crucial in regulating body temperature through the secretion of sweat, which is primarily composed of water. As sweat evaporates from the skin surface, it helps cool the body down. Lactic acid, a product of metabolism, can also be found in sweat, particularly after physical activity when muscles break down sugars for energy, leading to increased lactic acid production. The presence of lactic acid in sweat can contribute to its slightly acidic nature. Though other substances might be present in smaller amounts in sweat, the primary components of sweat from sudoriferous glands are indeed water and lactic acid, making this the correct choice.
