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 any rate, Lewis was found at daylight with a gunshot to the chest and one to the head, and, apparently, several knife wounds. He died shortly thereafter. Meriwether Lewisâs death cannot and should not be put down to suicide. The suicide story simply has too many holes in itand too much evidence arguing strongly against it.
