Thymus

The thymus is an organ found in the neck of humans and other vertebrates which plays a vital role in the development and functioning of the immune system. It is composed of two lobes of soft tissue which contain a type of white blood cell called T-lymphocytes. These cells protect the body from infection and disease by attacking foreign material and abnormal cells. The thymus is a major site for the production of hormones which help regulate the immune system, as well as being responsible for the maturation of T-lymphocytes. Without a functioning thymus, the body is more prone to infection and certain types of cancer. Therefore, a healthy thymus is essential for a healthy immune system and overall well-being.
