According to my Biology text, the first air breathing animal was a Scorpion-like Arthropod, about 444 million years ago.
campylobacter moves by a infected animal or human coughing ir sneezing and another human or animal breathing in that air you can also get it by eating contaminated food or water.
If you mean 'respiratory system'.....then it starts at the nose (breathing in is the first process before the air can reach the lungs for filtering out of oxygen into the blood stream). Breathing in is referred to as inhalation (of air), and breathing out is exhalation. Try browsing through the Biology categories (Human Anatomy, etc.) for the technical details, if you need them.

Breathing
Every air breathing animal can.
it gives them air in the their lungs
Blue Whale
The same way as any air-breathing animal - through its lungs !
fish - fins cockroach-air tube earthworm- skin
Air breathing life appeared on earth about 400 million years ago, a little bit after the first plants came. The first air to be breathed was by insects.
They get their air the same way we get ours by breathing it in and breathing it back out again this is the sane with every animal Ollie Mason Thank you and please read more of my answers on answer.com
You may mean 'suffocation', -this is when a breathing animal is denied enough air to breathe effectively.
Through their lungs - just like every other air-breathing animal.

Panting is rapid shallow breathing. It cools an animal by bringing in cooler air to the body, and it helps evaporate saliva in the mouth that also cools.
It is a mammal: a warm-blooded, air-breathing animal that nurses its young. All cats are mammals.
