Show answer & explanation
Correct answer: A
Explanation
Correct answer: Buccal Cavity
Explanation:
- Buccal Cavity: This is the initial part of the digestive system, located on the face. It contains the teeth, tongue, and salivary glands.
- Bile Duct: This is situated in the upper right section of the abdomen (stomach region), near the liver. It transports bile to the small intestine.
- Appendix: This is a small, tube-like structure attached to the beginning of the large intestine, located in the lower right section of the abdomen.
- Anus: This is the final part of the digestive system, situated in the lowest section of the body.
Key Facts:
- Initiation of Digestion: The digestion of food begins right in the buccal cavity, where the enzyme 'amylase' starts breaking down carbohydrates.
- Sequence of Organs: Mouth -> Esophagus (Food Pipe) -> Stomach -> Small Intestine -> Large Intestine -> Rectum -> Anus.
- Significance of the Appendix: In the human body, the appendix is considered a 'vestigial organ,' which currently performs no active digestive function.
