Lymphoid organs

LYMPHOID ORGANS ANATOMY

The tonsils, the spleen, and the thymus are also considered to be lymphoid organs. The tonsil creates a ring of protection, positioned between the nasal cavity, the pharynx, and the oral cavity.

LYMPHOID ORGANS STRUCTURE

The spleen is suspended off to the left of the stomach, along the left side of the abdominal cavity. While the spleen is not considered a vital organ in an adult human body, it does assist in the production of lymphocytes, as well as the filtering process and the destruction of the unnecessary or older lymphocytes.

In an infant’s or small child’s body, the spleen is considered a vital organ as it creates much needed erythrocytes. As the human body grows, the spleen develops red pulp and white pulp.

The red pulp is necessary for the destruction of the old and unnecessary erythrocytes while the white pulp’s germinal centers create the necessary new lymphocytes.

Deep to the manubrium of the sternum, within the thorax, the thymus if positioned and quietly plays a vital role in maintaining the body’s immune system.

The thymus shrink during puberty, and thus the thymus in the body of a small child or infant is much larger then the thymus of an adult human body.
