Exchange and transport systems in animals

The video explains how large multicellular organisms have evolved specialized exchange surfaces and transport systems to efficiently exchange gases and nutrients with the environment. It highlights the limitations of diffusion in large organisms due to a small surface area to volume ratio and describes adaptations like lungs and intestines that increase surface area for diffusion. The video also covers the role of transport systems in moving substances around the body.

In what ways do large multicellular organisms cope with a small surface area to volume ratio?

What role do transport systems like the circulatory system play in multicellular organisms?
