Verified step by step guidance

Identify the primary organ responsible for filtering and excreting waste products from the blood, which is the kidneys.

Understand that the kidneys play a crucial role in maintaining homeostasis by regulating the volume and composition of body fluids.

Recognize that the kidneys filter blood to produce urine, which is the primary means of excreting water and waste products from the body.

Consider the other options: lungs, intestines, and skin, and understand their roles in excretion. The lungs primarily excrete carbon dioxide, the intestines excrete solid waste, and the skin excretes sweat, which is a minor route for water loss.

Conclude that the kidneys are the main organ responsible for excreting most of the body's water through urine production.
