How a pet’s body works
Every animal has the same main systems working together. See inside a healthy, happy pet — then tap a system to learn what it does and how a vet gently checks it.
The skeleton
The frame of bones that holds the body up and protects the soft parts inside.
A vet looks: A vet gently watches how the animal walks — a limp or a sore spot is a clue.
The heart & blood
The heart pumps blood all around the body so every part gets what it needs.
A vet looks: A vet listens to the heartbeat with a stethoscope — a steady beat is a good sign.
The lungs
The lungs breathe air in and out so the blood can carry oxygen everywhere.
A vet looks: A vet listens for calm, quiet breathing — coughing or fast breaths are clues.
The tummy
Turns food into the energy the body runs on, and carries away what is left over.
A vet looks: A vet asks whether the animal is eating and feeling settled.
