Answer 2

Answer:

Mouth

MouthThe anterior opening of the alimentary canal is the mouth. It leads to a buccal cavity or oral cavity, where teeth, tongue and salivary glands are present. Here, ingestion, mastication, and swallowing of food occur. In humans, there are a total of 32 permanent teeth. There are four different types of teeth, namely, incisors, canines, premolars, and molars. These help in the chewing of food.

Salivary Glands

Salivary GlandsThey are exocrine glands that produce saliva in the oral cavity. They secrete an enzyme called amylase, which helps in the breakdown of starch into maltose. There are three types of salivary glands, namely

• Parotid gland
• Parotid glandSubmandibular gland
• Parotid glandSubmandibular glandSublingual gland

Stomach

StomachThe oesophagus leads to a sac-like organ called the stomach. It is a muscular, hollow organ, having a capacity of 1 litre. The stomach holds food and also is a mixer and grinder. It secretes strong acids and powerful enzymes that help in the process of breaking down of food.

Small Intestine

Small IntestineThe small intestine is a long tube, which loosely coils in the abdomen area. Here, enzymes from the pancreas and liver further break down the food. Three segments make up the small intestines, which are the duodenum, jejunum, and ileum. The contractions of the small intestine help in the movement of food, along with its breakdown, after mixing with the digestive secretions. The jejunum and ileum areas of the small intestine are responsible for the absorption of food into the blood, though their villi.

Pancreas, Liver and Gall Bladder

The pancreas secretes enzymes which help in the breakdown protein, fat, and carbohydrate. The liver secretes bile and cleanses and purifies the blood coming from the small intestine. The gallbladder stores the bile that the liver produces.

Large Intestine

The large intestine is a long muscular tube that has different parts, which are caecum, colon, and rectum. The waste that is left over after digestion of food, reaches the rectum through the peristaltic movements of the colon.

The whole process starts in the oral cavity, where the saliva from the salivary glands mixes with the food and starts to begin the breakdown of food. From the mouth, the food passes to the hollow tube-like organ the oesophagus. From the oesophagus, food then travels to the stomach, where it breaks down further with the help of the acids and powerful enzymes secreted by the stomach.
