Alimentary canal runs from mouth to

The correct answer is: D. Anus.

The alimentary canal is a long, muscular tube that runs from the mouth to the anus. It is responsible for digesting food and absorbing nutrients. The alimentary canal is divided into the following parts:

• Mouth: The mouth is where food is chewed and mixed with saliva. Saliva contains enzymes that begin to break down food.
• Esophagus: The esophagus is a muscular tube that connects the mouth to the stomach. It moves food down to the stomach by peristalsis, which is a wave-like motion of the muscles.
• Stomach: The stomach is a muscular sac that stores food and begins to break it down further. The stomach also produces gastric juices, which contain enzymes that help to digest food.
• Small intestine: The small intestine is a long, coiled tube that is responsible for most of the digestion and absorption of nutrients. The small intestine is divided into three parts: the duodenum, jejunum, and ileum.
• Large intestine: The large intestine is a shorter, wider tube that absorbs water and salts from food. The large intestine is also responsible for forming and storing feces.
• Rectum: The rectum is a short, muscular tube that connects the large intestine to the anus. The rectum stores feces until they are eliminated from the body.
• Anus: The anus is the opening at the end of the digestive tract. It is through the anus that feces are eliminated from the body.
