From a medical and scientific perspective, the abdomen and abdominal cavity are two different parts of the human body having their characteristics.
Key Takeaways
- The abdomen is the body part between the chest and pelvis, while the abdominal cavity is the space within the abdomen that contains the digestive organs.
- The abdomen includes the skin, muscles, and organs, while the abdominal cavity is a specific anatomical space.
- The abdomen can be palpated and examined externally, while the abdominal cavity is only accessible through surgery or imaging.
Abdomen vs Abdominal Cavity
The abdomen is a small area a person can see between the human body’s thorax (chest) and pelvis. The abdomen also includes the muscles and skin on the body’s exterior. The abdominal cavity is the space within the abdomen that contains the stomach, intestines, liver, and other organs.
The abdomen is present in all mammals, including humans. This is what we call, in simple terms, the belly. The abdomen is a small area a person can see between the pelvis and the chest in the human body.
The Abdominal cavity takes up the most significant space in the human body. Even though it takes up a lot of room, it is just one organ that is a part of the cavity.
The abdominal cavity is the place that is seen below the abdomen present in the human body. It is in between a person’s diaphragm and the public line.
Comparison Table
| Parameters of Comparison | Abdomen | Abdominal Cavity |
|---|---|---|
| Definition | The abdomen is a small area that a person can see between the chest in the human body and the pelvis in the human body. | The abdominal cavity is the place that is seen below the abdomen present in the human body. |
| Visual | The abdomen is possible to be seen through the naked eye. | The abdominal cavity is not possible to be seen through the naked eye. |
| Abdominal layers | The abdomen has layers containing the cell and muscle layers. | The abdominal cavity comprises suspended visceral organs situated inside it. |
| Role | The abdomen plays a role of an insulator in protest to the abdominal cavity. | The abdominal cavity provides housing for the internal organs. |
| Size | The abdomen is smaller in size compared to the abdominal cavity. | The abdominal cavity is more prominent in size compared to the abdomen. |
What is Abdomen?
The abdomen is present in all mammals, including humans. This is what we call, in standard terms, the belly. The position of an abdomen can be different for vertebrates and invertebrates.
The abdomen in the human body is said to have a lot of tissues and muscles. This helps function our locomotion and gives the body the support it needs.
These muscles present in the abdomen act as a line of protecting all the organs inside the abdomen. A person can build muscles for better protection through exercise, yoga, and sports.
In an animal body, the abdomen helps to separate the chest from the thorax from the pelvic lining. Vertebrate animals have their abdomen enclosed with skeletons.
The uppermost layer present in the abdomen helps in protecting the abdominal cavity too. The other layer, which is fat enough, helps maintain the body’s heat by performing metabolic activities by acting as an insulator.
What is the Abdominal Cavity?
The Abdominal cavity takes up the most significant space in the human body. Even though it takes up a lot of room, it is just one organ that is a part of the cavity. The abdominal cavity is the place that is seen below the abdomen present in the human body.
The cavity in abdominal cavity contains the innards and viscera.
The internal organs inside the abdominal cavity are the kidneys, pancreas, liver, spleen, adrenal gland, and all of the parts in the alimentary canal, including the small and large intestines.
The most important feature of the Abdominal cavity is that it is the most prominent place in the human body. A thin layer of cells called the peritoneum is present in the abdominal cavity, which helps to cover the abdominal cavity.
Main Differences Between Abdomen and Abdominal Cavity
- The abdomen is a small area that a person can see between the chest in the human body and the pelvis in the human body. On the other hand, the abdominal cavity is the place that is seen below the abdomen present in the human body.
- The abdomen can be seen through the naked eye; conversely, the abdominal cavity cannot be seen through the naked eye.
- The abdomen contains cell and muscle layers, and on the Other hand, the abdominal cavity comprises suspended visceral organs inside it.
- The abdomen is small in size, and on the other hand, the abdominal cavity is larger.
