Which of the following conducts waste removal?

1. Respiratory system

2. Circulatory system

3. Genitourinary system

4. Nervous system

The correct answer is: Genitourinary system

The genitourinary system is primarily responsible for waste removal in the body through the processes of urination. This system includes the kidneys, ureters, bladder, and urethra. The kidneys filter blood to remove waste products and excess substances, converting them into urine, which is then excreted from the body. By regulating the composition of body fluids, the genitourinary system plays a crucial role in maintaining homeostasis, balancing electrolytes, and ensuring the elimination of metabolic waste. While other systems contribute to waste removal, such as the respiratory system (which expels carbon dioxide) and the circulatory system (which transports waste products to the excretory organs), they do not specifically focus on waste elimination in the same manner as the genitourinary system. The nervous system, on the other hand, is primarily involved in transmitting signals throughout the body and does not directly participate in the removal of waste. Thus, the genitourinary system stands out as the primary system dedicated to the task of waste removal, making it the correct choice here.
