Gastrointestinal System
The gastrointestinal tract (GI tract, digestive tract, alimentary canal) is the tract or passageway of the digestive system that leads from the mouth to the anus. The GI tract contains all the major organs of the digestive system, in humans and other animals, including the esophagus, stomach, and intestines. Food taken in through the mouth is digested to extract nutrients and absorb energy, and the waste expelled at the anus as feces. ''Gastrointestinal'' is an adjective meaning of or pertaining to the stomach and intestines. Most animals have a "through-gut" or complete digestive tract. Exceptions are more primitive ones: sponges have small pores (ostia) throughout their body for digestion and a larger dorsal pore ( osculum) for excretion, comb jellies have both a ventral mouth and dorsal anal pores, while cnidarians and acoels have a single pore for both digestion and excretion.

Types Of Cancer
The following is a list of cancer types. Cancer is a group of diseases that involve abnormal increases in the number of cell (biology), cells, with the potential to invade or spread to other parts of the body. Not all tumors or lumps are cancerous; benign tumors are not classified as being cancer because they do not spread to other parts of the body. There are over 100 different known cancers that affect humans. Cancers are often described by the body part that they originated in. However, some body parts contain multiple types of tissue, so for greater precision, cancers are additionally classified by the List of distinct cell types in the adult human body, type of cell that the tumor cells originated from. These types include: * ''Carcinoma'': Cancers derived from epithelium, epithelial cells. This group includes many of the most common cancers that occur in older adults. Nearly all cancers developing in the breast cancer, breast, prostate cancer, prostate, lung cancer, lung, p ...
