"The lung is not a sterile organ," Dr. David Cornfield, a pulmonologist at
Packard Children's and a professor of pediatrics in pulmonary medicine at
the Stanford School of Medicine, said in a university news release. "This
research confirmed a long-held suspicion that a forest of microbes exists in
both healthy and diseased lungs."

Anything you breathe in, dust, germs particulates, all pass through the lungs, so no; the air inside would not be sterile. It'd be contaminated by anything you've taken in.

If a sterile field becomes "contaminated" with a sterile solution, the field remains sterile.

I think Pleural (lungs), Peritoneal (abdomen), and Pericardial (heart) fluids are normally sterile. Also, synovial (joints) and cerebral spinal fluids.
No it's not sterile
Some examples of sterile body fluids include cerebrospinal fluid (CSF), pleural fluid, pericardial fluid, peritoneal fluid, and synovial fluid. These fluids are typically free from microorganisms and are important for various physiological functions in the body.
Four sterile sites in the human body are the brain and cerebrospinal fluid, the blood, the lower respiratory tract (including the lungs), and the bladder (when not infected). These sites are normally free from microorganisms to prevent infections.
No, sterile saline is a solution of salt (sodium chloride) in sterile water, while sterile water is just water that has been sterilized. Sterile saline is commonly used in medical procedures and wound cleaning, while sterile water is used for irrigation and as a diluent for medications.
Sterile is clean and clean is sterile, so both
Yes, and I wouldn't be surprised if the cat did die from this. The lungs are a sterile environment for the most part, but the stomach can have all sorts of bacteria in it. Also, the vomit is very irritating (remember the burning sensation at the back of your nose the last time you threw up?), which causes a massive inflammatory response in the lungs that can basically flood the lungs with water and drown the cat.
The healthy human lung is sterile
