Answer:
Venous return (VR) is the flow of blood back to the heart.
Venous return to the right atrium is the most important factor determining cardiac output, provided both ventricles and the pulmonary circulation are normal.
Explanation:
Venous return refers to the flow of blood from the periphery back to the right atrium, and except for periods of a few seconds, it is equal to cardiac output.
Venous return is facilitated by a number of factors, including inspiration, increased total blood volume, increased venomotor tone, the cardiac suction effect, the presence of venous valves and the skeletal muscle pump.
Contraction of the skeletal muscles surrounding veins increases the pressure within the veins, pushing open the proximal valve and forcing blood toward the heart. For example, when calf muscles contract during exercise, blood is forced toward the heart, thus increasing venous return.

Waves pull away in a srtright line because the the disturbance action of transferring energy is done without an outside influence and in the same medium as well
<h3>What is a wave?</h3>
A wave is defined as a disturbance which travels through a distance, transferring energy from one place to another
Some few types of waves are
- Electromagnetic waves
- Matter waves
- Mechanical waves
So therefore, waves pull away in a srtright line because the the disturbance action of transferring energy is done without an outside influence and in the same medium
