Oesophagus
You are correct. The organ that is not a part of the digestive system is the mouth.
To determine the answer, you can break down the question and analyze each option:
A. Esophagus: The esophagus is a muscular tube that connects the mouth to the stomach, allowing food to pass through it. It is a part of the digestive system.
B. Gallbladder: The gallbladder is a small pear-shaped organ located beneath the liver. Its main function is to store and concentrate bile produced by the liver. Bile aids in the digestion and absorption of fats. Therefore, the gallbladder is a part of the digestive system.
C. Kidneys: The kidneys are a pair of bean-shaped organs located on either side of the spine. They play a crucial role in the filtration of blood, regulation of fluid balance, and removal of waste products from the body. However, the kidneys are not directly involved in the process of digestion. They are part of the urinary system, not the digestive system.
D. Mouth: The mouth, also known as the oral cavity, is the opening through which food enters the digestive system. It is responsible for the initial mechanical breakdown of food through chewing and the production of saliva. Therefore, the mouth is indeed a part of the digestive system.
Based on the analysis, the correct answer is option C: Kidneys. The kidneys are not a part of the digestive system.
