Which organs remove excretory products from the blood?

The organs that remove excretory products from the blood are primarily the kidneys. Here's a step-by-step explanation:

1. The kidneys are responsible for filtering the blood. They do this by removing waste products, such as urea and creatinine, along with excess water and electrolytes. This forms urine, which is then stored in the bladder.

2. The liver also plays a role in excretion. It processes and breaks down toxins, drugs, and other substances in the blood. The waste products from this process are then excreted in the bile, which is eventually eliminated from the body through the feces.

3. The lungs are another organ involved in excretion. They remove carbon dioxide, a waste product of cellular respiration, from the blood. This is exhaled out of the body.

4. The skin, through sweat glands, also helps in excreting waste products such as urea, salts, and water.

So, the main organs that remove excretory products from the blood are the kidneys, liver, lungs, and skin.
