Which of the following cavities would contain your stomach?
a. Peritoneal
b. Pericardial
c. Pleural
d. Thoracic
Introduction:
The space between the parietal peritoneum and visceral peritoneum is called a peritoneal cavity. The peritoneal cavity is filled with peritoneal fluid, which is composed of electrolytes, leukocytes, antibodies and water. This fluid has lubrication and anti-inflammatory properties.
Answer to Problem 1U
Correct answer:
The peritoneal cavity extends from the diaphragm to the floor of the pelvis. It has two divisions; abdominal cavity and pelvic cavity. Therefore, option a. is correct.
Explanation of Solution
Reason for the correct statement:
The peritoneal cavity is a potential space between the parietal peritoneum, which lines the abdominal wall, and the visceral peritoneum, which envelopes the abdominal organs. It is present in the stomach.
Option a. is given as “peritoneal”.
As the “peritoneal cavity surrounds the abdominal organs such as the stomach, liver, gallbladder, pancreas, spleen, kidneys intestine, and ovaries in (female)”, it is the right answer.
Hence, option a. is correct.
Reasons for the incorrect statements:
Option b. is given as “pericardial”.
Pericardial cavities enclose the heart in humans. Therefore, it is a wrong answer.
Option c. is given as “pleural”.
Pleural cavities house the lungs in humans. Therefore, it is a wrong answer.
Option d. is given as “thoracic”.
The thoracic cavity is subdivided into the pleural cavity that houses the lungs, mediastinum that surrounds the thoracic organ, and pericardial cavity that encloses heart. Therefore, it is a wrong answer.
Hence, options b., c., and d. are incorrect.
Conclusion:
The peritoneal cavity is subdivided into; abdominal cavity that contains stomach, liver, gall bladder, spleen, small and large intestine, kidney and ureters, and pelvic cavity that contains bladder, the terminal end of the large intestine and internal reproductive organ.

- PCBs and River Otters: Otters in Washington State’s Green-Duwamish River have high levels of polychlorinated biphenyls (PCBs) in their livers. PCBs can bind to the estrogen receptors in animals and disrupt the endocrine system of these otters. The PCBs seem to increase the estrogen to androgen ratio, skewing the ratio toward too much estrogen. How would increased estrogen affect the river otter population?

You submitted a paper to a peer-reviewed journal that addresses the factors that impact fruit type and seed dispersal mechanisms in plants of Central America. The editor of the journal communicates that your paper may be published if you make ‘minor revisions’ to the document. Describe two characteristics that you would expect in seeds that are dispersed by the wind. Contrast this with what you would expect for seeds that are gathered, buried or eaten by animals, and explain why they are different. (Editor’s note: Providing this information in your discussion will help readers to consider the significance of the research).arrow_forward
