In the human body, all the parts of human play an important role in living a good and healthy life. But all organs have their own and different role, and each organ is categorised for its role. So, do you often realise which is the largest gland in the human body?
Among all the organs in our body, the liver holds a special place—not only because of its size but also due to the many critical roles it plays. The liver is located on the right side of the abdomen, just beneath the ribs.
The liver is a reddish-brown, spongy organ roughly the size of a football. In an average adult, it weighs about three pounds, making it the largest internal organ and the biggest gland in the human body.
In this article, let’s explore in detail the largest gland in the human body, which is none of the Kidney only.
Which is the largest gland in the human body?
The liver is the largest gland in the human body. Liver is doing its functions as both an exocrine gland by producing bile for digestion, and it also acts as an endocrine gland by releasing important proteins and hormones into the blood. The liver also helps in detoxifying harmful substances by aiding metabolism and maintaining body balance.
Why is the Liver Called a Gland?
The liver is often described as both an organ and a gland. The liver, which is an internal part of the human body, is also known as a gland because it produces important substances that the body needs to function properly. Specifically, it acts as an exocrine gland by secreting bile, which is a fluid that is essential for digesting fats, directly into the intestines. At the same time, it also has to perform the endocrine functions, which help in filtering the blood.

What is the structure of the Liver?
The liver is divided mainly into two parts: a larger right lobe and a smaller left lobe. These lobes contain numerous blood vessels through which blood flows. As blood passes through the liver, toxins and waste products are filtered out and eventually expelled from the body through urine and faeces.
Inside the lobes are thousands of tiny units called lobules. These lobules connect to a network of bile ducts, small tubes that transport bile from the liver to the small intestine, where it aids digestion.
