Yes.
Gravity does not help the blood circulate any better than it already does. circulation functions solely upon the circulatory system (heart, veins, etc.). If gravity played a role in circulation of the blood the man on the moon probably would have died and we would never have been in space.
Veins have valves in them which help transport the blood.
Nope.
The heart is the pump of the cardio vascular system, and the arteries and the veins help to circulate the blood around the body
what two things help the blood in veins return to the heart
magnets can help blood circulate around bones
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.
Since the blood in your veins is traveling back to your heart, it is fighting gravity. In order to help the blood along, veins have valves that will close after the blood has gone through to prevent backflow. Also, when muscles contract, it pushes the blood upwards because of the contraction.
The contraction of muscles and one-way valves in the veins help facilitate the flow of blood through the veins.
Veins and Arteries move the blood throughout your body which are part of the Respiratory System with the help of the heart pumping the blood.
because of the blood muscles that push the heriastic pulley. the move the blood through the veins and arteries.
Veins.
