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 mantle
Neptune stays in orbit around the Sun due to the gravitational pull between the two bodies. The Sun's gravity keeps Neptune in its orbit, just as it does for all the other planets in the solar system. This balance between the Sun's gravitational pull and Neptune's orbital speed keeps it from moving away or falling into the Sun.
If a 100 amp breaker keeps tripping there is an overload on the system.
The sun holds celestial bodies in the solar system through its gravitational pull. This gravitational force keeps planets, moons, asteroids, and other objects in orbit around the sun. The balance between the sun's gravity and the forward motion of the celestial bodies keeps them moving in stable orbits.
The ball keeps moving forward because of its momentum, which is not a force.
