Answer:

heart is a important organ of the human system

Answer 2

Explanation:

Your heart is a vital organ. It is a muscle that pumps blood to all parts of your body. The blood pumped by your heart provides your body with the oxygen and nutrients it needs to function. Your heart is about the size of a clenched fist, and weighs between 300 and 450 g.

Newton's Second Law of motion states that the rate of change of momentum of an object is proportional to the applied unbalanced force in the direction of the force.

ie., F=ma
