Respiration
Main organs of respiration are the lungs, where oxygen from the atmosphere diffuses across the thin membrane separating the air in the Alveoli (the smallest, sac-like structures in the air-containing part of the lungs) into the bloodstream and carbon dioxide - the product of the energy-producing reactions in the body - travels in the opposite direction, to be expelled to the atmoshere.
The heart is also important in respiration, as it is responsible for pumping de-oxygenated blood to the lungs, where it becomes oxygenated; and also drawing the oxygenated blood from the lungs and pumping it into thel system for distribution around the body. Including the soft issues of lungs, the heart, and muscles.
communication: Cheetahs communicate with each other using a variety of sounds. Cheetahs don't meow, but they do chirp and squeak. Mother cheetahs chirp to call their young. They also purr to show contentment and growl to show aggression. Cheetahs also communicate using body language, like other cats. Flattened ears and bared teeth mean aggression, and this is accentuated by white spots on the backs of black ears.
