What else can I help you with?
Is blood flow faster in veins?
Blood flow is faster in arteries than in veins. Blood flow in veins is lower pressure.
Do capillaries have valves to regulate blood flow?
Capillaries do not have valves to regulate blood flow. Veins are the vessel of the circulatory system that have veins to regulate blood flow.
How is blood flow direction controlled in veins?
There are one-way valves (leaflet valves) in the veins which normally allow blood to flow only back to the heart. Muscle pressure is the main force pushing blood back from the extremities, especially against gravity in the legs. When the valves malfunction or are affected by high blood pressure, the vessels can form varicose (swollen) veins, blue veins, or spider veins.
What helps facilitate the flow of blood through the veins?
The contraction of muscles and one-way valves in the veins help facilitate the flow of blood through the veins.
Which force must the flow of blood overcome as it moves from the feet back up to the heart through the veins?
Gravity
What does ficiliate the flow of blood?
Veins
Which type blood vessels does the blood flow to the heart in?
Veins.
Blood flow from leg to heart?
Veins
What direction does the blood flow in the heart?
there are two main veins that makes the blood flow toward the heart which are the superior vena cava and inferior vena cava.
What prevents blood in the cardiovascular system from going backward?
blood flows into the veins quiet slowly as they are much wider compared to the flow of blood in the arteries which are rather narrow.because of the low pressure of blood on the flow inside the veins there are great possibilities that the blood is likely to flow backwards which may cause complications in the flow of blood.to prevent this from happening the veins contain valves that stop the back flow of blood
Ventricle force blood directly into what?
The ventricles contract and force the blood under pressure, past the semi lunar valves into the arteries. The closing of the bicuspid and tricuspid valves prevents back flow. At the same time the atria and ventricles relax and blood begins to flow back into them from the veins.
Where does the blood flow through?
Veins and artery's and Capillaries
