Final answer:
A new opening of the large intestine to the outside of the body is called a colostomy or ileostomy, created for waste elimination when the regular pathway through the rectum and anus is not available.
Step-by-step explanation:
A new opening of the large intestine to the outside of the body is known as a colostomy or ileostomy, depending on the specific location where the opening is created. The large intestine, which includes the colon, rectum, and anus, has a crucial role in absorbing water and electrolytes, as well as storing and eliminating waste as feces. In some cases, when parts of the colon or rectum are removed due to diseases such as cancer, a new pathway for waste elimination is necessary. This involves creating an opening in the abdomen where the end of the remaining bowel is brought to the skin's surface, allowing waste to exit the body into a special bag.
