Question about capillary action

Does capillary action happen due to the adhesive properties of water? Is it a matter of water clinging to the object with greater surface area?

The walls of a capillary consist of a single layer of cells, so nutrients, dissolved gasses, and waste products can easily pass through them.

A quick google:

Non sequitur. Capillaries don’t use capillary action - the blood is pushed through them.

I didn’t say they do. InvidiousCourgette did, citing a source. I said that since the wall contains a single layer of cells, nutrients and waste are able to pass through.

We’re not talking about capillaries in the circulatory system, though. We’re talking about the properties of water in a capillary tube. The phrase “capillary action” is pretty much universally understood to mean what InvidiousCourgette’s link discusses.
