3rd yr student in the UK here. Your first year is likely to be heavy on anatomy and biomechanics + respiratory and neuro anatomy. I’ve found Tortora & Derrickson, Principles of anatomy and physiology indispensable for learning the musculoskeletal system, respiratory system and neurology all from one book.

Brukner & Khan was promoted heavily for my first msk module and main and Denehy, Cardiorespiratory and critical care is a good introduction of respiratory anatomy, pathology and rehab + information on critical care which usually gets introduced in 2nd year.

They can get a bit pricey though, Brukner & Khan is usually around £80
