Verified step by step guidance

Understand the role of the excretory system: The excretory system is responsible for removing waste products from the body to maintain homeostasis. It includes organs such as the kidneys, liver, lungs, and skin.

Identify the primary waste products: The kidneys filter blood to remove waste products like urea and creatinine, which are byproducts of protein metabolism and muscle activity, respectively.

Differentiate between the substances listed: Bile and insulin are not waste products; bile aids in digestion, and insulin regulates blood sugar. Carbon dioxide is expelled by the respiratory system, not the excretory system. Glucose and amino acids are nutrients, not waste products.

Focus on urea and creatinine: These are the correct substances produced by the excretory system to eliminate waste. Urea is formed in the liver and transported to the kidneys for excretion, while creatinine is a waste product from muscle metabolism.

Conclude with the correct answer: Urea and creatinine are the substances produced by the excretory system to eliminate waste from the body.
