Physiology
Definition
Physiology is a branch of biology that studies how organisms function or work. It looks at how various body systems interact to help an organism survive and thrive.
Analogy
Imagine physiology as a car mechanic who understands how every part of your car works together. Just like how a mechanic knows what makes your engine run or brakes stop, physiologists understand how our bodies' systems work together for us to live healthily.
