A draining tract or tunnel that develops in scar tissue is often referred to as a sinus tract or fistula. These structures can form as a result of infection, inflammation, or chronic irritation, leading to a pathway that allows drainage of pus or fluid from an underlying abscess or pathological process to the skin surface. Sinus tracts are commonly associated with conditions like hidradenitis suppurativa or certain types of chronic wounds. They can complicate healing and may require medical intervention for management.
The type of epithelial tissue that lines the urinary tract are a special form of epithelium cells. These cells allow the tract to stretch.
The intestinal tract develops from the endoderm, one of the three embryonic germ layers. The endoderm gives rise to the epithelial lining of the digestive tract, including the intestines, stomach, and associated organs like the liver and pancreas.

The digestive tract is generally not associated with lymphoid tissue, with the exception of small collections of lymphocytes such as Peyer's patches.
The nasopharyngeal lymphatic tissue is the mucosal lymphoid tissue of the respiratory tract.
In the lining of the respiratory tract.
The tissue that lines internal organs is called epithelial tissue. It acts as a protective barrier and helps with the absorption and secretion of substances in the body. Epithelial tissue can be found in the digestive tract, respiratory tract, and other organs.

Four layers of tissue form the walls of the digestive tract. These layers are called mucosa, submucosa, muscularis externa and adventitia.

The tissue lining your inner nasal passages is made from ectoderm. However, the rest of the respiratory tract lining is made of endoderm.
