Summary Introduction

Introduction:

The peritoneal cavity is the largest serosal sac and considered as the largest fluid filled cavity in the body. Most of the intra-abdominal organs are covered by this cavity. The peritoneal cavity is made up of a layer of mesothelium that is supported by thin layer of connective tissue. The peritoneal lining of the cavity performs the function of a channel for blood vessels, lymphatic vessels and nerves of abdominal organs.

Answer to Problem 1MC

Correct answer:

Peritoneal cavity is a potential space containing serous fluid, like pleural and pericardial cavities.

Explanation of Solution

Explanation for correct answer:

The peritoneal cavity is a space that is present between the partial peritoneum and visceral peritoneum. The cavity contains the fluid that consists of water, electrolytes, leukocytes, and antibodies. This fluid acts as a lubricant and permits the free movement of abdominal viscera. It does not contain air or any digestive organs. The pancreas and duodenum are present in the abdominopelvic cavity. Hence option (c) is the correct answer.

Explanation for incorrect answers:

Option (a) states that peritoneal cavity is the same as the abdominopelvic cavity. Abdominopelvic cavity contains the abdominal cavity and pelvic cavity, whereas peritoneal cavity lies between the partial peritoneum and visceral peritoneum. Thus this option is incorrect.

Option (b) states that peritoneal cavity is filled with air, whereas there is no air in this cavity. Thus this option is incorrect.

Option (d) states that peritoneal cavity contains the pancreas and the entire duodenum. Pancreas and duodenum are present in abdominopelvic cavity, not in peritoneal cavity. Thus this option is incorrect.

Conclusion

Thus it is concluded that peritoneal cavity is a space that is present between the partial peritoneum and visceral peritoneum and it consists a serous fluid that contain water, electrolytes, leukocytes, and antibodies.
