Blood flows slower in veins than arteries because veins have valves.
Veins carry deoxygenated blood back to the heart, whereas the heart pumps oxygenated blood through the arteries to the body. Because it is going to the whole body, this blood needs to be at a high speed and under lots of pressure. Thus the heart contracts and pumps it through thick, muscular arteries under high pressure.
Veins are thinner walled and have valves so that there is no backflow of deoxygenated blood due to the low pressure of the blood in veins. If veins were under high pressure they would gush into the heart and cause it to burst/explode.

Do valves in the veins keep sluggish blood?
If your asking if they slow the blood down... no, they open to allow blood to flow with the beating of the heart, but close to prevent back flow/flowing away from the heart
Is blood flow faster in veins?
Blood flow is faster in arteries than in veins. Blood flow in veins is lower pressure.
How is the blood flow controlled in the veins?
The veins have valves in them
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.
What lab values are not affected by sluggish blood flow?
Potassium
What does ficiliate the flow of blood?
Veins
Which lab value is not affected by sluggish blood flow in the neonate?
potassium
Is bilirubin lab value affected by sluggish blood flow?
yes
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
