Which system is responsible for removing waste and toxins from the body?

The excretory system is indeed responsible for removing waste and toxins from the body. This system includes organs such as the kidneys, ureters, bladder, and urethra, which work together to filter blood and eliminate waste products through urine. The kidneys play a crucial role by filtering out impurities and maintaining the balance of electrolytes and fluids in the body. This process is vital for regulating blood pressure and ensuring that harmful substances are efficiently removed, thus preventing their accumulation in the blood and tissues.

In contrast, the digestive system is primarily involved in breaking down food, absorbing nutrients, and eliminating undigested material, but it's not directly responsible for detoxifying the body. The nervous system mainly controls and coordinates bodily functions and responses but does not engage in waste removal. The circulatory system transports blood throughout the body, delivering nutrients and oxygen to cells and removing carbon dioxide, but it does not primarily handle waste elimination. Therefore, the excretory system is the correct answer as it is specifically designed for processing and expelling waste and toxins.
