The Milky Way is the galaxy that includes our Solar System, with the name describing the galaxy's appearance from Earth: a hazy band of light seen in the night sky formed from stars that cannot be individually distinguished by the naked eye. The Milky Way is a large barred spiral galaxy.

In medicine , particularly plastic and reconstructive surgery, leeches may be used to help improve blood flow in an area of tissue or a skin flap that has poor blood circulation. Leeches do this by removing clotted blood (congested blood) from delicate areas, such as underneath a flap of skin or on a finger or toe.
