The cardiovascular system. It provides nutrients and oxygen to the entire body and removes waste and carbon dioxide through the circulation of blood. The pumping action of the heart keeps the blood flowing through the vessels and the system pressurized.
The Circulatory System......
The mantle
what your talking about is terminal velocity, which is when the downward force of gravity (Fg)equals the upward force of drag (Fd). This causes the net force on the object to be zero, resulting in an acceleration of zero
Active uptake is necessary when a substance moves from an area of low concentration to an area of high concentration. This requires the use of energy and transport molecules in the cell membrane.
If a 100 amp breaker keeps tripping there is an overload on the system.
The ball keeps moving forward because of its momentum, which is not a force.

The Gravity and Rotation in our solar system.
Peristalsis.
keeps blood moving through the heart and vessels
your heart is a pump and keeps the blood flowing
inertia keeps moving it!:)
The pumping of the heart keeps the blood moving
The rotation of the earth keeps a foucault pendulum moving
The nucleus is the thing that keeps us moving because, oh just go to biology4kids.com
