Answer:
surgical puncture into the pelvic cavity to remove fluid from the space between the rectum and uterus, called the rectouterine pouch (Douglas's cul-de-sac).
Answer:
The correct answer will be option-is secreted by the epithelial cells of both layers of the serous pericardium
Explanation:
Serous fluid is a fluid which resembles the serum of the blood in its color which is pale yellow to transparent.
The serous fluid is present in the cavities of the body organs like in heart, the fluid is present in the pericardial cavity.
The serous fluid lubricates the wall of the heart and is produced by the serous pericardial membranes. The secreted fluid gets collected between the pericardial cavity which helps slide the smooth movement of the serous layer against each other.
Thus, secreted by the epithelial cells of both layers of the serous pericardium is the correct answer.
