That is probably the reproductive system, since it ensures the continuation of the human population by creating more individuals to replace humans that die.
A planet orbits around a star, such as the Sun in our solar system. The gravitational pull of the star keeps the planet in its orbit as it travels through space.

Plant earth is the third planet from the sun. This is partly why earth can sustain life. This keeps the temperature reasonable for life to exist.
Gravity is what keeps a planet in orbit around the sun. The gravitational pull between the planet and the sun causes the planet to continuously fall towards the sun, but its forward motion prevents it from getting any closer and keeps it in a stable orbit.
The force of gravity between the moon and the planet is what keeps the moon in orbit around the planet. This gravitational force prevents the moon from floating away into space and keeps it in a stable orbit.

what keeps planet earth from fallin out of the sky
The planet's gravity.
the forse of gravity keeps it floating in space like the moon orbits our planet

The skeleton system is important to the human body because it keeps the human body upright and protects the body's internal organs against injuries.
Gravity and its velocity
Force of gravity is what keeps the planets form colliding.
the suns gravity keeps the planets in orbit
help u breathe The respiratory system includes the heart and lungs. The lungs take in oxygen which pumps blood through the whole human body and to the heart. This process keeps the heart pumping which keeps you alive.
The system which is comprised of 206 pieces and keeps us standing is the skeletal system. The adult human body has 206 bones which provide the support structure for the internal organs and the attachment places for muscles, tendons, and ligaments.
