IS THIS RIGHT FOR MOD 8 TECHNOLOGIES?? --i need to re-explain dialysis lol

EYE:
- glasses --fix myopia (short sightedness with concave lenses) and hyperopia (long sightedness with convex lenses)
- laser surgery --fix astigmatism and other things

EAR:
- outer ear issues: hearing aid
- middle ear issues: bone conductive implant (bypasses outer+middle - directs vibrations straight to inner)
- inner ear issues (uh oh that sucks): cochlear implant (bypasses the whole damn ear by stimulating auditory nerve directly)

KIDNEY:
- dialysis --basically performs the transfer of salts and fluids and filtration of blood that would be done in the kidney with nephrons, but outside the body because the kidney doesn't work (using specific dialysis fluid that runs opposite direction to blood)
- two types:
----haemodialysis --attached to machine
----peritoneal dialysis --can be done at home

For Mod 8, the stuff about the nervous and endocrine system is far too convoluted for me. Esp all the terminology eg: axons, dendrites and its hard to remember each term and its function. Can anyone suggest a simple way to break it down so I can understand it better? Thanks.

Hello!
Please do not pull an all-nighter. It destroys your concentration and health. No matter how tempting it is. Maybe you can do it over 2-3 days? I mean, there is still time for the Biology HSC.
You got this!

A quick question, when the syllabus asks to "evaluate the effectiveness of" what exactly does it mean? NESA defines "evaluate" as making a judgement based on criteria or determining the value of. When it says effectiveness, do we just list the advantages/disadvantages? If not, how to evaluate effectiveness in Bio?
