Did you know the liver is the largest solid organ in your body, located predominantly on the right side? If you've been asking What major organ is on my right side?, understanding your anatomy is the first step toward better health awareness and identifying potential issues.
The Liver: The Largest Organ on Your Right
The most significant organ situated primarily on the right side of the body is the liver. Located in the upper right-hand portion of the abdominal cavity, it sits just beneath the diaphragm and above the stomach, right kidney, and intestines. This reddish-brown, cone-shaped organ is vital for numerous bodily functions and can weigh around 3 pounds in an adult. Its position, nestled safely under the rib cage, means any pain or discomfort in the upper right abdomen could potentially be related to liver health.
The Liver's Multifaceted Roles
The liver is often referred to as the body's chemical factory because it performs hundreds of vital functions essential for survival. Some of its most crucial roles include:
- Detoxification: It filters all the blood in the body and breaks down poisonous substances, including alcohol and drugs.
- Bile Production: The liver produces bile, a fluid that is essential for the digestion and absorption of fats in the small intestine.
- Nutrient Processing: It converts excess glucose into glycogen for storage and regulates blood levels of amino acids, which form the building blocks of proteins.
- Vitamin and Mineral Storage: The liver stores significant amounts of essential vitamins (A, D, E, K, B12) and minerals (iron, copper).
- Blood Clotting Regulation: It produces certain proteins and regulating factors necessary for proper blood clotting.
Other Vital Organs in the Right Abdomen
While the liver is the largest and most prominent organ, several other key structures are also located on the right side of your body, distributed across different abdominal quadrants.
The Gallbladder
Tucked away just beneath the liver is the gallbladder, a small, pear-shaped organ. Its main job is to store and concentrate bile produced by the liver. When you eat, particularly fatty foods, the gallbladder releases this concentrated bile into the small intestine to aid in digestion. Issues like gallstones are a common cause of pain in the upper right abdomen.
The Appendix
In the lower right quadrant of the abdomen, you will find the appendix. It is a small, finger-shaped pouch connected to the large intestine. Though it was long considered a vestigial organ with no purpose, recent research suggests it may play a role in housing beneficial gut bacteria, helping to repopulate the gut after an illness. However, it is most commonly known for appendicitis, a painful inflammation that often requires surgical removal.
The Right Kidney and Adrenal Gland
Positioned more towards the back of the upper abdomen, your body has two kidneys, with the right kidney sitting slightly lower than the left to make room for the liver. Perched on top of the right kidney is the right adrenal gland. These retroperitoneal organs are crucial for filtering waste from the blood to produce urine, and the adrenal gland produces essential hormones.
Parts of the Intestines
The large intestine, specifically the cecum and ascending colon, travels up the right side of the abdomen. A significant portion of the small intestine is also located within the right side of the abdomen. Pain in these areas can be caused by a variety of gastrointestinal issues, from gas to more serious conditions like inflammatory bowel disease.

Understanding the Abdominal Quadrants
For diagnostic purposes, doctors often divide the abdomen into four quadrants to better localize pain or other symptoms. The right side is divided into the right upper quadrant (RUQ) and the right lower quadrant (RLQ). Knowing what organs reside in each quadrant can be helpful in identifying potential health problems.
- Right Upper Quadrant (RUQ): Includes the liver, gallbladder, right kidney, and part of the large and small intestines.
- Right Lower Quadrant (RLQ): Contains the appendix, cecum (first part of the large intestine), and parts of the small intestine. In females, the right ovary and fallopian tube are also located here.
When to Worry About Right-Sided Pain
While minor aches can often be due to gas or muscle strain, severe or persistent pain on your right side should not be ignored. It's crucial to seek medical attention if right-sided pain is accompanied by:
- Severe, sudden, or worsening pain, especially in the lower right abdomen.
- A high fever and chills.
- Abdominal swelling or tenderness.
- Yellowing of the skin and eyes (jaundice).
- Persistent nausea or vomiting.
- Bloody stools or blood in the urine.
Comparing Right-Side Organs
| Organ | Location | Primary Function | Common Issue |
|---|---|---|---|
| Liver | Upper right abdomen | Detoxification, digestion, metabolism | Hepatitis, fatty liver disease, cirrhosis |
| Gallbladder | Under the liver | Stores and concentrates bile for digestion | Gallstones, inflammation (cholecystitis) |
| Appendix | Lower right abdomen | Contains beneficial bacteria (immune role) | Appendicitis |
| Right Kidney | Towards back of upper right abdomen | Filters waste from blood to make urine | Kidney stones, infection |
Conclusion
While the liver is the most prominent major organ on the right side of your body, it is by no means the only one. Understanding the location and function of the gallbladder, appendix, right kidney, and parts of the intestines is key to recognizing the signs and symptoms of potential health issues. Persistent pain or severe symptoms on your right side should always be evaluated by a healthcare professional to ensure a correct diagnosis and timely treatment.
