An IV injection, if you are injecting into a blood vessel, then you bypass absorption reach maximal level in the blood.
Blockage to any major blood vessel is potentially fatal for a few reasons. If the blood doesn't flow properly, insufficient oxygen will reach the rest of the body, which is important to survival. As well, if the heart attempts to work overtime to compensate for this, blood pressure could rise to levels where major vessels could rupture, causing internal bleeding.
White blood cells pass through the vessel wall into surrounding tissue through a process called diapedesis. During diapedesis, the white blood cell first attaches to the endothelial cells lining the blood vessel. It then squeezes through these cells to reach the surrounding tissue where it can carry out its immune functions.
Blood pressure is highest in arteries, specifically in the large arteries like the aorta, as they receive blood from the heart during systole and distribute it throughout the body. This high pressure enables the blood to reach all tissues and organs efficiently.
Collateral circulation provides alternate pathways for blood to reach an organ if the usual route is blocked or restricted. It helps to ensure that vital organs receive adequate blood supply even if there is an obstruction in a blood vessel.
They travel dissolved in the blood plasma.
I will tell you what a capillary is, but you should figure it out from there. A capillary is the tiny blood vessel that connects veins and arteries. The blood would go through the capillaries to reach one or the other. Remember: Arteries and veins each carry old or new blood. I can't remember what does what.
When white blood cells leave the capillaries, this process is called diapedesis or extravasation. It allows white blood cells to move from the blood vessel into the surrounding tissues to reach sites of infection or inflammation.
