decreases  There is not enough information to answer this question. returns What is the function of serous fluid? It helps the stomach and other organs maintain neutral buoyancy within body cavities,  even during fluctuations in atmospheric pressure, or when gases, such as oxygen or  methane, are present in varying ratios. It enables organs, such as the heart and the stomach, to slide across cavity walls and  each other without friction. It prevents the organs from drying out when in contact with air. It aids in the repair of damaged organs. It enables organs, such as the heart and the stomach, to slide across cavity walls and  each other without friction.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
