Which of the following organs is NOT part of the digestive system?

The bronchi are not part of the digestive system; they are part of the respiratory system. The primary function of the bronchi is to transport air to and from the lungs, allowing for the exchange of oxygen and carbon dioxide. In contrast, the stomach, mouth, and large intestine are all integral components of the digestive system responsible for the mechanical and chemical breakdown of food, absorption of nutrients, and elimination of waste. The mouth initiates digestion, the stomach further breaks down food with acids and enzymes, and the large intestine absorbs water and compacts waste for excretion.
