Melting point: Melting point, temperature at which the solid and liquid forms of a pure substance can exist in equilibrium. As heat is applied to a solid, its temperature will increase until the melting point is reached. More heat then will convert the solid into a liquid with no temperature change.
Overall, in humans, the large intestine is about 1.5 metres (5 ft) long, which is about one-fifth of the whole length of the gastrointestinal tract.
The intestine is the portion of the digestive tract between the stomach and the anus. It is divided into two major sections: small intestine and large intestine. The small intestine is about 6 meters (20 feet) long. It is coiled in the center of the abdominal cavity (see picture). The small intestine is divided into 3 sections: upper, jejunum, and ileum. The lining of the small intestine secretes a hormone called secretin, which stimulates the pancreas to produce digestive enzymes. The large intestine has a larger width but is only 1.5 meters (5 feet) long.
