Why water and dissolved substances leave the arterioles end of the capillary and enter the venule end?

Water and dissolved substances leave the arteriole end of the capillary due to hydrostatic pressure being higher than osmotic pressure and enter the venule of the capillary due to osmotic pressure being higher than hydrostatic pressure.

Why arterioles6 times thicker than the average venule?
The arterioles wall contains smooth muscle and elastic fibers and is six times thicker to handle the higher pressure in the arterioles. The venule is like a giant capillary.
The glomerular capillaries differ from other capillary networks in the body because they?
It is unique from other capillary beds in that it is supplied with and drained by arterioles, the afferent arteriole and efferent arteriole, respectively.
What structure within a capillary bed shunts blood from arteriole to venule?
Artery -> Arteriole -> Capillary -> Venule -> Vein
What is a tiny blood vessel that connects in arteriole to a venule?
The blood vessels in between arteries and veins are the capillaries. But, they do not link them together, rather, they both have openings, through their capillaries, into the interstitial space which is the space between the cells of the tissues of the body.
What type of vessel does a capillary receive blood?
Capillaries send blood to both arteries and veins.
What are the functions of venule?
The venule is a very small vein. Arteriesalways take blood away from the heart but these arteries are too large for exchange of gasses and nutrient/wastes to occur. The arteries branch into smaller and smaller arteries. The smallest are called arterioles. The arterioles feed into capillary beds where this exchange can occur as the walls of the capillaries are very thin. Venules lead from the bed into larger and larger veins.
What are the smallest vessels that connect veins arteries?
Capillaries
What is the difference between arteriole and venule blood flow?
An arteriole transports oxygenated blood from the arteries to the capillary beds and a venule transports de-oxygenated blood from the capillary beds to the veins.
How does blood flow from capillary to venule?
By the process of diffusion.
What are the blood vessels that drain blood directly from the capillary beds?
venule(veins)
The smallest blood vessel?
The smallest arteries of the human body are the arterioles, which supply blood into the capillary network from the main arteries (artery-->arteriole-->capillary-->venule-->vein). They hold plasma and filtrates, and are usually only wide enough to hold a single red blood cell at a time (in some cases, they are smaller than a RBC).
What is the opposite of venule?
The venules are small vessels that connect capillaries to veins.The corresponding vessels that feed into the capillaries are arterioles.
