We wouldn't be able to use oxygen to burn fuel to produce energy. In our cells this takes place in specialized organelles called mitochondria, which organize the enzyme pathways needed to run the Krebs Cycle, which transfers electrons from food to oxygen and generates 32 molecules of the currency of energy, ATP, from each food molecule.
The whole anatomical structure of the Respiratory System - trachea, lungs, etc. - exists just to deliver oxygen in a timely manner to those mitochondria.
Without it, our cells would have to get by on the ancient system of Fermentation, which is what cells used prior to Earth's having an oxygen-rich atmosphere, billions of years ago. Fermentation only yields 2 ATP per sugar molecule, as opposed to 32. You can see why respiration became preferred by Evolution!
it is simple we can't breath and live.
respiratory system Circulatory system
Nothing much will happen.
in a cell different cell organelles do different functions(e.g. mitochondria-respiration) in the same way our body has different organs or different organ systems to do different functions(heart-respiration;digestive system-complete digestion and excretion of food)
The circulatory system performs many vital functions. It plays an important role in respiration. The circulatory system is also important in nutrition, in the removal of wastes and poisons, and in several other body processes.
There Is two kinds of respiration through your mouth and also your nose
In the lungs. That's where gas exchange and respiration takes place
You would die.
Respiration
No function, no life!
Aerobic respiration will be stopped. Body will not get enough energy
respiration system
Then the human body wouldn't exist. XD
Everyone and it happens because our body needs energy.
The end result would be death.
respitory, digestive, curculitory, & uranary
respiration
Your body might not grow or mature properly.All body function would be deranged and death would occur .
