A stomach is found in the upper abdomen part on the left side of a body. Extraction of important nutrients is often found to be dependent on the efficiency of a digestion system. The efficiency of stomach parts plays an important role in ensuring a proper digestion process within a digestive system in humans.
Components of digestive system
The digestive system in the human body consists of some organs. The whole process of digestion is considered to be one of the most important processes of the human body. In order to maintain a healthy body, a proper digestion process is necessary.
Mouth
Pharynx
Esophagus
Stomach
Small and large intestine
Anus
These are the most important components of a digestive system in humans. Besides all these components, pancreas, gallbladder, and liver are considered to be two important solid organs that help in the digestion process.
Importance of the digestive system in human body
In the human body, the digestive system plays a crucial role. The strength and weakness of a body depend on the efficiency of a body to digest food in a proper manner.
Digestive system in humans is important to extract nutrients from food
This system is important for breaking down the food into some particles that are necessary for extracting available nutrients in that particular food
The extracted nutrients help the human body to gain energy and also to grow
In terms of repairing damaged cells, nutrients are essential. The digestive system in humans is significant in this regard
In terms of maintaining the hormone levels in the human body, the digestive system is very important
The process of digestion
A whole digestion process can be divided into the most important six significant parts.
An important step of this process can be mentioned as ingestion. This process is all about taking food by mouth. One of the primary steps of a digestive process is the step of ingestion
Another step is propulsion which is an act of movement of the food through the digestive tract. A series of relaxations and alternating contractions are included within this
Mechanical as well as physical digestion is considered as an important part of the digestive system in humans. This is a wholly physical process in which the chemical nature of the food is found not to be changed
Chemical digestion is an important step of the digestion process in which complex molecules such as carbohydrates, fats, and proteins are found to be transformed into digestive components. The hydrolysis process can be mentioned as an important part of the chemical digestion process
Absorption is an integral part of the digestive system in which simple molecules and nutrients pass through the blood cells, membranes
The defection process is considered as the final step of a digestion process by which the elimination of feces, semi-solid and liquid waste materials is done
Parts of a stomach with functions
Parts | Functions |
|---|---|
Cardia | The cardia is considered as the topmost part of a stomach that is close to the esophagus. The liquid and food pass through the cardia to enter the stomach. |
Fundus | This part is considered to be the storage of gas that is produced during the time of digestion. |
Corpus | Corpus is considered as the largest part of a stomach. Mixing food and preparing for digestion are done in this part. |
Antrum | This is the lower part of the stomach. This part is considered to hold the half-digested food before being released into the small intestine. |
Pylorus | It is an important valve that helps in passing the partly digested food particles into the small intestine. |
Conclusion
The digestive system in humans is important to maintain a healthy body. An efficient process of digestion is important in acquiring essential and necessary proteins from food. In order to grow and maintain health, food is consumed. Lack of digestion can present challenges for a body to ensure a healthy body. Some important parts are there that help a stomach to provide quality service in the digestion process. There is a valve near the cardia that prevents the food from returning back to the esophagus after entering the stomach. In terms of excessive food, fungus part of the stomach is found to store food.
