Detailed explanation-3: -The spaces between endothelial cells and the fenestrae allow alcohol to diffuse by filtration into the blood, with the concentration gradient. Once alcohol enters the capillaries, it is carried by the bloodstream into the veins where it can then be distributed throughout the entire circulation.

Detailed explanation-4: -The urea is transported from the liver to the kidneys using the circulatory system. Here, urea is filtered out of the blood and ends up in the bladder as part of urine.
