Due to Newton's first law of motion, also known the law of inertia.
The first law states that an object at rest will stay at rest, and an object in motion will stay in motion unless acted on by a net external force.

if the bloos is moving to the upper part of the body it will exit through what?
New research stresses the importance of having a strong upper body when it comes to running efficiency. Training your upper body improves your running because it helps you prevent fatigue and improves endurance.

Yes, running tops add quite a bit of upper body support when running. They are a good idea to wear.
An elliptical stepper with upper arm moving bars will work both upper and lower body muscles.
You can not run without moving your upper limbs in contra lateral positions to lower limbs. (Try to run with upper limbs tied to your body.) Importance of running in football needs no comment. Also imagine the goalkeeper not using his upper limbs!
Imagine that you are standing inside a stationary bus. Suddenly the bus starts moving and you fall backwards. This is due to the inertia of your body. When the bus was at rest, you were also at rest. When the bus started moving, your legs went with the floor of the bus due to friction. But the upper part of your body tends to continue in its state of rest (inertia of rest). As a result you fall backwards.

Most of the muscles of the body are exercised when running. Of course the foot and leg muscles are needed the most but the muscles of the torso and upper body are used as well.
The original running style is rugby is the "bucking" run. Using a goose step while bucking the upper body.
