<p>Lymphatic tissue develops during early life reaching maximum size during early adulthood. Some regression (involution) occurs as the animal ages but is not complete.</p>

==Structure==

==Structure==

<p>The appendix is a blind ending out pouching of the [[Caecum - Anatomy & Physiology|caeca]] at the ileocaecal junction in the intestines. The lamina propria of the appendix contains a high number of [[Lymphocytes|lymphocytes]] as well as having a number of lymphatic nodules.</p>

<p>The appendix is a [[Bursa of Fabricius - Anatomy & Physiology|bursa]] equivalent organ and consequently has functions associated with maturation and differentiation of [[Lymphocytes#B Cells|B lymphocytes]].</p>
