The actions or forces that allow blood in the veins to return to the heart is that the blood in the veins is moving through the veins at a lower pressure, so the valves and muscular pumps withing the body help the blood circulate back to the heart.

respiration, blood vessels allow for oxygen carrying, cilia allow for filter feeding.
In hot weather - blood vessels dilate (widen) - to allow the exchange of heat between the blood and sweat glands. The sweat evaporates - cooling the blood.
Vascular tissues allow for the transport of blood. The vascular system includes the veins, arteries, and capillaries.
The blood is able to move to and from the heart through the contraction of the heart muscle. These contractions build up pressure and cause you to have what is commonly known as blood pressure. That build up of pressure pushes the blood throughout the arteries and veins and enables it to circulate throughout the body.
Muscular contraction in the extremities moves the blood through the veins, the valves only allow blood to move toward the heart.
Return blood, most likely, refers to the venous blood that is returned to the heart.
Veins return blood to the heart.The pulmonary veins.
how do the bronchi allow the oxygen to get to the blood
what two things help the blood in veins return to the heart
Blood is pumped by the heart.
Deoxygenated blood return form the body to the heart via the Superior and Inferior Vena Cavas, which join together to enter the Heart's Right Atrium.
veins
The blood vessel that returnes blood to the heart is called Veins.
