Bone marrow examination.

A wharf is a platform built on the shore that extends over the surface of the water. On the wharf, you saw people preparing to set sail. A wharf provides access for ships and boats, that can pull up and dock alongside it. In fact, wharfs are also called docks or piers. Wharfs are made of wood and act like sidewalks, making it easy to people, cargo and supplies to enter and leave a boat. As a verb, wharf means to moor, or tie the boat to the wharf and drop an anchor, or to be given a place at the wharf.
A marina is a dock or basin with moorings and supplies for yachts and small boats. A marina differs from a port in that a marina does not handle large passenger ships or cargo from freighters. The word marina is also used for inland wharves on rivers and canals that are used exclusively by non-industrial pleasure craft such as canal narrowboats. In some countries, Marina is used as a Christian female name.
