The air travels through a system of organs called the respiratory system. This system includes organs such as the nose, trachea, bronchi, and lungs, which work together to bring oxygen into the body and remove carbon dioxide.
You breath through a respiratory system for short you breath through your lungs
The organs in the renal system are the kidneys, ureters, bladder, and urethra. The kidneys filter waste and excess fluids from the blood to form urine, which then travels through the ureters to the bladder for storage before being excreted through the urethra.
The digestive tract that carries food includes the mouth, pharynx, esophagus, stomach, small intestine and large intestine. Other organs, such as the pancreas, are part of the digestive system, but don't carry the food.
Oxygen flows into the body through the respiratory system. When we breathe in, oxygen is inhaled through the nose or mouth, travels down the trachea, and then into the lungs where it is absorbed into the bloodstream and carried to the body's cells.
Deer breath through there lungs, and out there nose or mouth. That's why people always try to shoot them in there vital organs (there lungs)
skin is also an organ through which we breathe 2 lungs 1 nose 1 treachea 2 bronchi 1 mouth
Once you breathe in oxygen through your nose, it travels through the trachea, then to the bronchi. The bronchi helps to get oxygen to your lungs. After the air passes through the bronchi, it travels through the bronchioles which are smaller tubes than the bronchi which are bigger tubes than the bronchioles. From the bronchioles air goes to the alveoli. Then it travels back out through the bronchioles, then through the bronchi until the carbon dioxide waste is out of your system. Hope i helped :)
The organs in the repiratory system, help you breathe. When the oxygen is in the body, the heart pumps it around to help the blood.
the circulatory system
The circulatory system is the way your blood travels throughout your body. It starts at the heart, then is pumped to the organs that need it.
Koalas breathe in oxygen through their nose, which then travels down their windpipe and into their lungs. Inside the lungs, oxygen is absorbed into their bloodstream and circulated throughout their body to support cellular functions.
