It is composed of lymphoid tissue and epithelial cells. It consists of two irregularly shaped lobes united by a connective tissue capsule. Each lobe is subdivided by connective tissue septa into lobules, which consist of an inner medullary zone, continuous with the medullae of adjacent lobules, and an outer cortical zone. The cortex is rich in lymphocytes (thymocytes) and the medulla in epithelial cells. This gland is supplied by the inferior thyroid and internal thoracic arteries, and its nerves are derived from the vagus and sympathetic nerves. The thymus is the site of T-lymphocyte production, necessary in early life for the normal development of immunological function. The thymus reaches its greatest relative weight shortly after birth and its greatest absolute weight and maximal development at puberty. It then begins to involute resulting in a slow decline of immune function throughout adulthood.

It is a compound gland composed of both exocrine and endocrine tissues. The endocrine pancreas makes insulin so that the body can use glucose (sugar) for energy. The exocrine pancreas makes enzymes that help the body digest food. Spread all over the pancreas are areas called the Islets of Langerhans. The cells in these areas each have a special purpose. The alpha cells make glucagon, which raises the level of glucose in the blood; the beta cells make insulin; the delta cells make somatostatin. There are also PP cells and D1 cells, about which little is known.

Ovarian_Tissue Venous_Sinus Venous Sinus Epididymis Epididymis Small Intestinal Goblet Cell Small_Intestinal_Goblet_Cell A unicellular mucous cell found in the epithelium of the small intestine. Droplets of mucigen collect in the upper part of the cell and distend it, while the basal end remains slender, and the cell assumes the shape of a goblet. Mucosa arranged into two fundamental structures - villi and crypts of Lieberkuhn. Villi are projections into the lumen of the small intestine, covered with simple columnar epithelium. Crypts of Lieberkuhn are moat-like invaginations of the epithelium around the villi that extend through the lamina propria down to the muscularis mucosae. Lymphocytes often invade the epithelium or form solitary lymphoid nodules in the lamina propria. Lymph nodules may form longitudinal aggregations of 30-50 nodules in the lamina propria of the ileum. These large aggregations are called Peyer's patches. The muscularis mucosae has two layers and extends into the intestinal villi, where the smooth muscle cells form a longitudinal bundle in the centre of the villi. The small intestinal mucosa secretes gastrin, somatostatin, cholecystokinin and secretin. Small Intestinal Mucosa Small_Intestinal_Mucosa Bone_Cell Osseous Cell Bone Cell Lymph Node Tissue Tissue composed of specialized cells that are organized as a definite organ, situated along the course of lymphatic vessels, and consisting of an outer cortical and an inner medullary part.
