9 lip 2024 · Frequently Asked Questions. Organ weight is a complex subject. There are many factors—including body weight, height, lean body mass, and race—that cause organ weights to vary widely. To figure out accurate ranges for organ weights, a lot more data need to be collected.
The following reference ranges (95% inclusion) are proposed: brain, 1179-1621 g; liver, 968-1860 g; spleen, 28-226 g; right lung, 155-720 g; left lung, 112-675 g; right kidney, 81-160 g; and left kidney, 83-176 g.
An enlarged liver could be a sign of a serious condition that requires medical treatment. Find out the normal liver size and what might be the cause of liver enlargement.

It weighs between 1.2-1.6 kg (3.5 lbs.) The liver is the largest gland in the body, accounting for about 2% of the body weight in adults and 5% in infants. It is also the largest abdominal organ. It usually weighs more in males than females. The right lobe is usually six times as large as the left.
The liver is about 2% of body weight in the adult, which amounts to approximately 1400 g in females and 1800 g in males. The liver receives its blood supply from two sources: 80% is delivered by the portal vein, which drains the spleen and intestines; the remaining 20%, the oxygenated blood, is delivered by the hepatic artery.
For women, best-fit regression lines for median and percentiles organ weight by body weight for the heart (A), liver (B), spleen (C), and lungs (left lung, D; right lung, E). Abbreviations: P10, 10th percentile; P25, 25th percentile; P75, 75th percentile; P90, 90th percentile.
