Lymph gland is a common term used to describe the small, oval-shaped glands that are found throughout the body's lymphatic system. These glands are an important part of the immune system as they help to filter out harmful substances and defend against infections. However, there are also several other names for lymph glands that are commonly used, including lymph nodes, lymphatic nodes, and lymphoid glands. These terms all refer to the same type of gland, and are used interchangeably by doctors and other healthcare professionals. Regardless of the name used, the lymph gland plays a critical role in helping to keep the body healthy and free from disease.
