Capillaries connect the smallest branches of arteries and veins The walls of capillaries are just one cell thick. Capillaries therefore allow the exchange of molecules between the blood and the body's cells - molecules can diffuse across their walls. This exchange of molecules is not possible across the walls of other types of blood vessel.
No. A vein is more likely to collapse.

That space will collapse on itself forming a cauldera.
Arteries carry blood away from the heart and empty into Arterioles which then lead to Capillaries, the blood then begins its return trip to the heart by entering Venules which empty into Veins which return the blood to the heart.ArteriesArteriolesCapillariesVenulesVeins
This answer presumes that "empty" means the bottle has no water in it, but does have air in it.In this case the bottle would collapse (or partly collapse) if the temperature inside the bottle dropped to a lower temperature causing the air inside to shrink, or if the bottle was taken to a place of higher air pressure (such as taking the bottle from a mountain peak to the base of the mountain.The bottle would also collapse at some point of evacuation if "empty" means the bottle was evacuated of water and air. The point of collapse, in this case, would depend on the physical construction of the bottle - ie, whether it was made of steel, plastic or glass

Blood flows from the heart and aorta into large vessels called arteries, these arteries decrease in size as they move into tissues and are then called arterioles with just a few layers of cells. Arterioles then become capillaries that have a single cell layer. Capillaries then empty into venules, which then enter veins and return blood back to the heart to start the process over again!
· Although similar to blood capillaries, lymphatic capillaries differ structurally in the following ways: · The endothelial cells forming the walls of lymphatic capillaries are not tightly joined. Their edges loosely overlap one another, forming flaplike minivalves. The flaps, anchored by fine collagen fibers to surrounding structures, gape open when the fluid pressure is high in the interstitial space, allowing it to enter the lymphatic capillary. · Bundles of fine filaments anchor the endothelial cells to surrounding structures so that any increase in interstitial fluid volume separates the cell flaps, exposing gaps in the wall rather than causing the lymphatic capillary to collapse.
Capillaries The smallest of the blood vessels: capillaries.
Capillaries are the structures that connect arteries to veins.
Arteries "feed" the capillaries while veins drain the capillaries.
