31 FOUR major BODY MEMBRANES line body cavities & internal spaces of organs & tubes opening to the outer environment 1. Mucous membranes n Line tissues that open to the exterior of the body – most have glands n Respiratory, digestive, reproductive, urinary – line tubes and cavities n Varied functions – i.e., designed to secrete and/or absorb substances 2. Serous membranes n Line the thoracic and abdominal cavities and the organs within them n Enclose heart and lungs, etc n Secrete serous fluid – lubrication From Fig. 4.8 – from Starr and McMillan, Human Biology , 10ed, Brooks/Cole

    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.
