Which three body systems are responsible for removing waste products from the body?

• A. Digestive, Muscular, and Circulatory
• B. Digestive, Integumentary, and Excretory
• C. Nervous, Lymphatic, and Endocrine
• D. Respiratory, Immune, and Integumentary

Answer: (B)

The correct answer emphasizes the roles of the digestive, integumentary, and excretory systems in the process of waste removal from the body.

The digestive system is primarily responsible for processing food and absorbing nutrients, but it also plays a critical role in eliminating solid waste through feces. Waste products that are not used or absorbed are ultimately expelled from the body through this system.

The integumentary system, which includes the skin, acts as a barrier and plays a vital role in excreting waste through sweat. This process helps regulate body temperature and remove small amounts of metabolic wastes.

The excretory system, also known as the urinary system, is crucial for filtering blood and removing waste products such as urea and excess ions, which are excreted as urine. This system maintains the body's internal balance of fluids and electrolytes.

In combination, these three systems work together to efficiently remove various types of waste from the body, ensuring that homeostasis is maintained.
