- **Duodenum**: The duodenum is the first part of the small intestine and can also be involved in vomiting if there are disturbances in digestion or absorption.
- **Hypothalamus**: The hypothalamus is a part of the brain that regulates various bodily functions, but it is not directly responsible for the act of vomiting.
- **Gastrointestinal Tract**: This is a broad term that encompasses the entire digestive system, from the mouth to the anus. While vomiting is related to the GI tract, it is not specific enough to pinpoint the exact cause.
- **Pancreas**: The pancreas is involved in hormone production and digestion but is not directly related to the act of vomiting.
