2.58: Describe the Role of the Plasma in the Transport of Carbon Dioxide, Digested Food, Urea, Hormones and Heat Energy

PLASMA: Straw-Coloured Liquid that Transports Dissolved Substances Around the Body Including:

SUBSTANCE	EXPLANATION
CARBON DIOXIDE	Plasma Carries Away Waste Carbon Dioxide from Respiring Cells to the Lungs for Exhalation in the Form of Carbon Dioxide or Hydrogen Carbonate Molecules
DIGESTED FOOD	Plasma carries Digested Food to Respiring Cells for Assimilation in the Form of Simple Sugars (E.g, Glucose) and Amino Acids
UREA	Waste Substances such as Urea is Carried by the Plasma from the Liver to the Kidney for Excretion
HORMONES	Hormones Produced by Endocrine Gland is Secreted in the Plasma to be Carried to Target Organs to Stimulate Chang
HEAT ENERGY	As Plasma is Mainly Composed of Water, Water has High Heat Capacity so is Important for Maintaining a Balanced Temperature in the Body (Optimum Temperature of 37°C)
