Spleen vs. Liver: What's the Difference?
Edited by Aimie Carlson || By Janet White || Published on December 9, 2024
The spleen is an organ involved in filtering blood and immune system responses, while the liver is responsible for detoxification, metabolism, and bile production.
Key Differences
The spleen primarily functions in filtering old red blood cells and aiding the immune system by producing white blood cells. The liver, the body's largest solid organ, is a metabolic powerhouse, processing nutrients from food, producing bile, and removing toxins.
Diseases of the spleen often involve enlargement or rupture, affecting its ability to filter blood effectively. Liver diseases, however, are diverse, ranging from hepatitis, cirrhosis, and fatty liver disease, often linked to diet, alcohol consumption, or viral infections.
The spleen is located in the upper left part of the abdomen, functioning as part of the lymphatic system with a focus on blood filtration. The liver is positioned in the upper right part of the abdomen, divided into two lobes, and plays a critical role in digestion and detoxification.
Both organs interact with the blood, the spleen's role is more directly linked to the immune system, monitoring and responding to blood pathogens. The liver's immune function is more indirect, breaking down pathogens as part of its detoxification process.
The spleen has a limited ability to repair itself after damage. In contrast, the liver is known for its remarkable capacity to regenerate even after significant injury, highlighting its vital role in the body's overall functioning.

Spleen and Liver Definitions
Spleen
An organ involved in filtering blood and housing immune cells.
The doctor explained that the spleen plays a crucial role in fighting infections.
Liver
A vital organ responsible for detoxification and metabolism.
The liver's detoxification process protects the body from harmful substances.
Spleen
Acts as a blood reservoir, releasing blood during physical stress.
In emergencies, the spleen contracts to provide extra blood to the body.
Liver
Processes nutrients absorbed from the digestive system.
After meals, the liver is busy processing and distributing nutrients.
Spleen
Removes old and damaged red blood cells from circulation.
The spleen's filtration of blood ensures only healthy red blood cells circulate.
Liver
Regulates blood sugar levels by storing and releasing glucose.
The liver helps maintain steady blood sugar levels throughout the day.
Spleen
Supports the immune system by producing lymphocytes.
The spleen's lymphocytes are essential for an effective immune response.
Liver
Produces bile, essential for digestion, especially fats.
Bile produced by the liver is stored in the gallbladder until needed for digestion.
Spleen
Vulnerable to enlargement or rupture from various conditions.
After the injury, the patient's spleen was carefully monitored for signs of rupture.
Liver
Capable of remarkable regeneration even after injury.
The patient's liver regenerated well after a portion was surgically removed.
Spleen
A large, highly vascular lymphoid organ, located in the human body to the left of the stomach below the diaphragm, that serves as a reservoir for blood, destroys old red blood cells, and contains lymphocytes that combat blood-borne antigens.
Liver
A large, reddish-brown, glandular organ in the abdominal cavity of vertebrates that secretes bile and is active in the formation of certain blood proteins and in the metabolism of carbohydrates, fats, and proteins.
FAQs
