Capillery walls need to be thin so oxygen, nutrients and otherthings including hormones can diffuse into cells, also thin capilleries are needed for waste products such as carbon dioxide and urea to diffuse out of cells.

What is a thin walled vein?
a capillary
How is the wall of a capillary suited for the exchange of materials in tissues?
The wall of a capillary is extremely thin.
What is the function of capillary net?
to spread the blood cells so thin that the oxygen can be taken into cells or transferred to other cells.
How does the thick capillary wall help blood move slowly?
Capillaries do not vary in thickness, they are very thin. The thin wall permits the exchange between the blood in the capillary and the adjacent tissue cells.
What is a capillary features?
A capillary has a very narrow lumn and very thin wall. These features maximize diffusion of nutrients, wastes, and oxygen.
Describe the structure of a capillary wall?
capillary walls are very thin, often a cell thick. artery walls have two thick layers.
Water can creep up thin tubes in?

How does the capillary help substanances pass through it?
Slow flow speed in the capillary increases the efficiency of diffusion. In addition, the thin wall of the capillary helps substances to pass through efficiently.
Why must air sacs have thin walls?
The air sac must have thin walls so that air passes easily through it.
When water is placed in a thin glass tube it tends to climb up the walls of the tube. This effect is known as capillary action. What causes this capillary action?
Hydrogen Bonding

What is capillary reaction?
Usually called 'capillary attraction' or 'capillary action' it refers to the way very thin tubes can draw water up themselves without any external changes in pressure or without suction being applied.
