what is the pleura

visceral membrane around the lungs

what is the peritoneum

lines abdominopelvic cavity

describe the difference between parietal and visceral membranes

parietal: line body cavity

visceral: line organs

what is the serous membrane

its two parts?

thin tissue layers that line closed body cavities, cover internal organs, and secretes mucus for lubrication

visceral and parietal

transverse: cuts the body into upper and lower half

frontal: cuts the body into anterior and posterior halves
