Have a feeling respiration will come up too.
What do you think the essay will be on?
- Heart, SAN and/or a graph
- Partial pressures/Hemoglobin
- Gene tech / Genetic fingerprinting
- Nitrogen cycle
- Digestion of lipids?
No bloody clue xD. Could be anything really. If it helps the specimen questions were; importance of movement, importance of receptors, nucleotides and water.
Good luck guys! We can do this
I also think heart can come up because it's a big part, also perhaps the nerves, e.g. Sympathetic and parasympathetic qs
