Capillary action.
Capillary
Diffusion.
The primary transport mechanism in intestinal cells is active transport, utilizing carrier proteins to move nutrients against a concentration gradient into the cell. This mechanism allows for the absorption of essential nutrients like sugars and amino acids from the intestine into the bloodstream for distribution throughout the body.
Blood hydrostatic pressure.
Continuous Capillary :)
With the slowness and low capacity of animal transport and wagons, boat transport by sea and river was by far the most important.
The most important force causing net water flow across capillary walls is the pressure difference between the hydrostatic pressure inside the capillaries and the oncotic pressure due to proteins in the blood. This pressure difference, known as the Starling forces, drives the movement of water out of the capillaries into the interstitial space.

Transport is important every where however Australia has larger distances to cover between important points of commerce and production then in most other continents..
