The heart is the primary force that moves blood through the body. As the heart contracts and releases the blood is then pumped through the vessels that travel to all areas of the body.
The primary force that moves the blood is the heart. The heart contracts and pumps blood into and out of the heart and into veins or arteries. There is a difference between the two, i suggest looking up these differences. This pumping allows you to have a pulse and thus, live. The primary force that moves the blood is the heart.

Water temperature is the primary force. Then the earth's rotation and the tides.
The pushing force that moves blood out of the heart is generated by the contraction of the heart muscle itself. When the heart contracts, it creates pressure that pushes blood into the arteries, allowing it to circulate throughout the body.
Gravity
Venous circulation. The arterial system moves oxygenated away from the heart to the rest of the body (as well as deoxygenated blood away from the heart to the lung). Blood moves mostly passively through the venous system, but muscular contractions in the legs help force blood upward (against gravity) to the heart when standing.
The driving force behind gas exchange in the human body is the concentration gradient of gases such as oxygen and carbon dioxide between the alveoli in the lungs and the blood in the pulmonary capillaries. Oxygen moves from the alveoli into the blood, while carbon dioxide moves from the blood into the alveoli, driven by differences in their partial pressures.
The primary driving force of wind is the uneven heating of the Earth's surface by the sun. This causes temperature variations which lead to differences in air pressure. Wind is then generated as air moves from high pressure to low pressure areas to equalize these differences.
The primary means of transportation is through the blood stream.
The heart does not just "help"- it is the primary force to push blood through the arteries to all parts of the body. It is a pump.

Friction force
The lungs are the primary organs that fill blood with oxygen. Oxygen from the air is inhaled into the lungs, where it moves into the bloodstream through tiny blood vessels called capillaries surrounding the lungs' air sacs.
