2.58 Understand the role of plasma in the transport of carbon dioxide, digested food, urea, hormones and heat energy

Plasma is made up of mostly water and is pale yellow in color (though I'm pretty sure you don't need to know that). This is a solvent, so things dissolve into the plasma, which is how they are carried around This transports carbon dioxide,  digested food, urea (basically urine...lovely), hormones and heat. 

Digested foods = soluble sugars and amino acids :)

Heat is important to regulate body temperature.

Figure 1 (below) shows a sample of plasma and blood - the plasma is the (rather gross-looking) yellow stuff above the red.
