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.
His father â who had co-founded a small auto insurance company named Progressive Insurance with Jack Green in 1937 â was grooming Lewis to work at the company when he died at age 48 while Lewis was a junior at Cleveland Heights High School. In 1955, he graduated from Princeton University.
