Assuming depoits is deposits, if there are "deposits" in the arteries, it restricts the flow and depending on how thick the deposit is, very little blood gets through. Imagine a fireman using the usual hose to kill a fire. Then imagine that he replaces that hose with a garden, say about 5/8 thich. The same water pressure and the same amount of water is still there but very little water gets through.
Same with deposits. The chamber is smaller. Now you have all kinds of problems, not to mention high blood pressure, poor circulation, etc., etc., etc., etc.

Arteries carry blood away from the heart and veins carry blood into the heart. Blood moving from the heart to the lungs through the pulmonary artery has less oxygen than blood moving from the lungs to the heart through the pulmonary vein, but most arteries carry oxygen-rich blood with little carbon dioxide, and most veins carry deoxygenated blood with carbon dioxide and other wastes.
The chambers of the heart function as a pump; they do not utilize the blood that passes through because it is moving far too quickly and turbulently. Blood must run through capillaries at lower speeds/volumes in order to be used by cells. The coronary arteries branch repeatedly to produce a vast network of capillaries that supply the cardiac muscle cells.
Nothing, it is only pressure that keeps blood moving in the right direction in arteries. Veins have valves that prevent backflow of blood, but arteries do not.
Elastic (conducting) arteries are the large arteries close to the heart that expand during systole, acting as pressure reservoirs, and then recoil during diastole to keep blood moving. Muscular (distributing) arteries carry blood to specific organs; they are less stretchy and more active in vasoconstriction. Arterioles regulate blood flow into capillary beds.

your heart is a pump and keeps the blood flowing
sup
You would see opening and shutting arteries and pumping moving blood

the Doppler effect involves moving objectsthe Doppler effect involves moving objects
valves are only present in veins to stop the blood to move backwards through the vein but in arteries the muscle puts alot of pressure on the blood which stops it from moving in the wrong direction
It is everthing involved in moving blood - heart, arteries, veins etc.
A group of balanced forces adds vectorially to zero, so has no effect on any object, whether it's moving or not moving.

The magnetic field will have no effect on a stationary electric charge. ( this means that the magnetic field is also stationary. ) If the charge is moving , relative to the magnetic field then there might be an effect, but the size and direction of the effect will depend on the direction of the electric charge as it moves through the field. If the charge is moving parallel to the field there will be no effect on it. If the charge is moving at right angles to the field then it will experience a force that is mutually orthogonal to the field and direction of the motion. You really need diagrams to properly explain this
No arteries do not contain valves since there is enough pressure from the heart to force blood through these vessels without significant backflow between contractions.
