Tethnically neither direction. All oxygenated blood goes from the lungs back to the Heart via the Pulmonary vein, where it gets pumped to the body, while the deoxygenated blood goes into the heart via the Vena Cava to be Pumped to the lungs for gas exchange. :)
Yes, in the northern hemisphere the currents flow clockwise.
clockwise
North Equatorial flow clockwise and southern counter-clockwise.
In the Northern Hemisphere, ocean currents generally flow clockwise due to the Coriolis effect, which is caused by the Earth's rotation. This means that currents are deflected to the right in the Northern Hemisphere. For example, the Gulf Stream off the east coast of the United States flows northward and then eastward across the Atlantic Ocean.
Northern
the oxygen-rich blood coming from the lungs enters the left atrium moves in anticlockwise to be distributed in the body
counter-clockwise
Counterclockwise and revenues flow counterclockwise.
The flow or blood
If you have your left hand on the skimmer basket or the inlet side of the pump, and you have your right hand on the return side of the filter or the clean water going back to the pool then the flow will be clockwise.
High
In the northern hemisphere, the surface currents generally flow in a clockwise direction due to the Coriolis effect, which is caused by the Earth's rotation. This means they move to the right of the wind direction in the northern hemisphere.
