Which body system includes the skin as part of its components?

• A. Endocrine
• B. Respiratory
• C. Excretory
• D. Digestive

Answer: (C)

Excretion is the process of removing wastes from the body. The excretory system includes organs that eliminate waste products and help regulate fluids and temperature. The skin contributes to this by producing sweat, which releases water, salts, and small amounts of urea. This makes the skin part of the excretory system, alongside the kidneys and urinary tract. The other systems don’t include the skin as a component: the endocrine system is about hormone-secreting glands, the respiratory system centers on breathing, and the digestive system focuses on breaking down and absorbing nutrients.
