Serous membranes line and enclose several body cavities where they secrete a lubricating fluid which reduces friction from muscle movement. Serous membranes are responsible for secreting serous fluids. Some organs that have serous membranes are the uterus, stomach, pericardium (the area that surrounds the heart), the pleural cavity (the area that surrounds the lungs) and the paritoneal cavity (the cavity that lines the abdominal organs).
Meriwether Lewis died at age 35. Meriwether Lewis was serving as governor of Missouri Territory in 1809 (just 3 years after the expedition ended). Lewis, a troubled individu â¦ al, was not suited for the bureaucratic life and found himself deep amongst petty and jealous administrators.
At the 1988 Olympics, he won the 100 meters and long jump. In 1992, he again won the long jump as well as the 4x100m, anchoring the U.S. team to a world record of 37.40. In 1996, in his final Olympics, Lewis had a dramatic farewell, winning his fourth-consecutive gold medal in the long jump. At age 30, he had one of his greatest achievements, breaking the world 100m record with a time of 9.86 while winning the event at the 1991 World Championships.
