How long will it take? The colonoscopy itself only takes about 30 minutes. The prep begins at home the evening before the procedure. The morning of your colonoscopy youâll spend about three hours at the clinic or hospital. Then youâll return home to rest for the remainder of the day. You can usually return to your usual activities the next day.
A pearl is a hard object produced within the soft tissue (specifically the mantle) of a living shelled mollusk or another animal, such as a conulariid.
Formation and Nature of Pearl: Pearl is secreted by the mantle of the pearl oyster as a protection against foreign objects which may be sand particles, minute larval forms or other such things. To study the mode of formation of pearl it is essential to know the structure of the shell and mantle.
