Answer 1

Hint: Human Digestive System and Nutrition involve the intake of food by an organism and utilize it for energy and other metabolic purposes. This is an important process that helps living beings obtain their energy from various sources. The food which we eat is broken down through various processes and nutrients present in them are utilized to generate energy.

Complete answer:
The digestive system of the human body is composed of the gastrointestinal tract and accessory organs. They both are important in the digestion process. The alimentary canal is the long tube through which the food passes. It begins at the oral cavity and passes through the pharynx, oesophagus or food pipe, stomach, small intestines, large intestines, rectum and finally, ends at the anus. Food particles gradually are digested with the help of digestive juices when they travel through various compartments of the alimentary canal. The human digestive system consists of;

- Mouth
- Teeth
- Salivary glands
- Pharynx
- Oesophagus
- Liver
- Stomach
- Pancreas
- Large intestine
- Small intestine
- Rectum

The process of digestion begins from the mouth and ends in the small intestine and the large intestine helps to absorb water from the undigested food. The undigested food is released from the body through the anus.

So, the correct sequence is Option A.

Note: Accessory organs like the liver and pancreas are organs that help in the digestion process but are not actually a part of GIT. They facilitate the digestion process by releasing certain enzymes that help in breaking down the food.

Some of the disorders of the digestive system are
i) Vomiting: It is the ejection of stomach contents through the mouth.
ii) Diarrhoea: It is an abnormal watery bowel movement that can due to many reasons
iii) Constipation: A condition of irregular bowel movement.
