The primary organ responsible for removing waste from the body is the kidney. The kidneys act as a filter, removing waste products and excess fluid from the blood to produce urine. This urine then travels through the ureters to the bladder for storage and is eventually expelled from the body through the urethra.
The Kidney's Role in Waste Removal
- Filtering Blood: The kidneys constantly filter the blood, removing waste products like urea, uric acid, and creatinine. [Source: Your kidneys remove wastes and extra fluid from your body. Your kidneys also remove acid that is produced by the cells of your body and maintain a healthy balance of water, salts, and minerals—such as sodium, calcium, phosphorus, and potassium—in your blood.]
- Maintaining Fluid Balance: Besides waste removal, the kidneys play a crucial role in maintaining the body's fluid balance by regulating the amount of water and electrolytes in the blood. [Source: Your kidneys remove wastes and extra fluid from your body. Your kidneys also ... removes wastes.]
- Acid-Base Balance: The kidneys also help regulate the body's acid-base balance, ensuring the blood pH remains within a healthy range.

Other Organs Involved in Waste Removal
While the kidneys are the main organs for waste excretion, other organs also contribute:
- Liver: The liver processes and removes various toxins and waste products from the blood. [Source: The liver removes toxins from the body's ... The liver is an essential organ of the body that performs over 500 vital functions. These include removing waste ...]
- Large Intestine: The large intestine eliminates solid waste through bowel movements. [Source: Although the kidneys are the main organs of excretion, several other organs also excrete waste s. They include the large intestine, liver, skin, ...]
- Skin: The skin excretes waste products through sweat. [Source: Although the kidneys are the main organs of excretion, several other organs also excrete waste s. They include the large intestine, liver, skin, ...]
- Lungs: The lungs exhale carbon dioxide, a waste product of cellular respiration.
The urinary system, which includes the kidneys, ureters, bladder, and urethra, works as a complete unit to efficiently remove liquid waste from the body. [Source: The urinary system includes your kidneys, ureters, bladder and urethra. This system filters your blood, removing waste and excess water.] Blood itself also plays a vital role in transporting waste products to these organs for removal. [Source: Blood also provides the cells with nutrients, transports hormones and removes waste products, which organs such as the liver, the kidneys or the skin excrete.]
