Gravity flow....if it was lower , the blood would flow to the iv bottle

the system works with gravity. the bottle has to be high up so the fluid drips down. if the bottle or bag was lower there are in the system traps that would not allow the persons blood to flow out and into the bag but the person would not get the fluid as it would be stopped by the one way valves.

This is to ensure that the liquid goes into the patients body by the force of gravity. At the same time, the level of fluid is immediately visible by any inspection.

Fluid flows by gravity.
The height of the bag must be a distance above the heart high enough for weight of the fluid to overcome the backpressure from the veins.

Because the fluid is higher than the arm it is going to flow down. Gravity. this way they don't have to have some crazy machine forcing the fluid in. it just happens naturally.

Gravity. It allows the liquid to flow down and into the vein.

Gravity does the work of delivering an air free solution this way, or it should if done right.

Because the liquid has to continue to drip and it can't do that at the same level as the arm or below it

Because the contents enter the bloodstream via hydrostatic pressure.
