to maintain blood flow and pressure
What 3 key factors about veins?
They carry deoxygenated blood their walls are thin their lumen is larger than arteries elasticity is less than artery bluish in color blood flows in vein is with low pressure their valves maintain unidirectional flow of blood
How do you use unidirectional in a sentence?

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?
Blood flow in the veins is controlled by contraction of the surrounding skeletal muscles, one-way valves in the vein walls that prevent backflow, and changes in pressure within the veins due to breathing and posture. These mechanisms help propel blood back toward the heart and maintain proper circulation.
The circulatory system consists of a series of vessels called?
arteries, veins, and capillaries. Arteries carry oxygenated blood away from the heart, veins return deoxygenated blood back to the heart, and capillaries are tiny blood vessels that connect arteries and veins.
What are the flaps of tissue that allow flow of fluid in only one direction?
Flaps of tissue that force unidirectional flow are called valves.
Why do vains have valves?
Veins have valves to prevent the backflow of blood. These valves ensure that blood flows in one direction towards the heart. Without valves, blood could pool in the veins and lead to conditions like varicose veins.
