Evolution of the transport system

The transport system of the body has evolved over time to become more efficient and effective. Early forms of transport were simple, such as diffusion and osmosis, which allowed for the movement of molecules and ions across cell membranes. As organisms became more complex, they developed more sophisticated systems, such as the cardiovascular and lymphatic systems, which allowed for the transport of larger molecules and cells throughout the body. Over time, these systems have become more efficient and specialized, allowing for the efficient transport of oxygen, nutrients, and other substances throughout the body.
