You can find the following on the Biology A level Revision Summary pages
The plasma makes up most of the blood. It is mainly water but carries lots of other essential ingredients.
The following substances are carried in the plasma:
Dissolved carbon dioxide: This is the waste gas produced by respiration in cells
Dissolved glucose and amino acids: Food molecules for respiration, building and repairing cells
Urea: Waste product of digestion, this is lost from the kidney.
Antibodies and antitoxins: Chemicals that protect us from disease and poisons
Hormones: Chemicals that control some of our body functions
Plasma has a yellowish appearance. It sometimes oozes out of blisters. Nice!
BLOOD is a fluid tissue which provides a link between all the other tissues and organs of the body.
It has the capacity to carry essential items around the body.
Oxygen from lungs to body cells
Carbon dioxide from body to lungs
Waste products and water from cells to kidneys
White blood cells to sites of infection
Platelets to damaged capillary areas
Glucose and nutrients from digestive system to cells
Hormones from glands to where they are needed
Heat from warmer to cooler parts of the body
Hi there. Most of it does, yes, but you need to keep an eye on the exact details of your course. We will be adding signposts to help with that in the future.

Absolutely - not a lot of democracy going on there. Anyone who wants to be emperor does not want to do a lot of listening to the people.
I think what you wrote is pretty much a definition of demand.
