means The branch of biology that studies how living organisms and their parts actually function — how organs, cells, and systems work and keep working.
from From Greek physis, 'nature,' plus -logia, 'study of' — so literally 'the study of nature,' specifically the workings of living things. It came into English through Latin and French around the 16th century, at first meaning natural philosophy broadly before narrowing to the science of how bodies operate.
