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!
What else can I help you with?
Which body systems are involved in respiration?
respiratory system Circulatory system
What would happen if your body temperature was 98.6 degrees celsius?
Nothing much will happen.
In what way could you compare your whole body to a single cell?
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)
What is the main job of the circularty system science?
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.
How many kinds of respiration occur in your body?
There Is two kinds of respiration through your mouth and also your nose
What would happen if the circulatory system failed your body?
You would die.
What system of the body is the most important?
Respiration
How would respiration in your body cells be affected if respiratory system did not bring enough oxygen?
No function, no life!
What would happen if our mitochondria did not have access to oxygen?
Aerobic respiration will be stopped. Body will not get enough energy
What would happen if the human body didn't have a respiratory system?
Then the human body wouldn't exist. XD
Who does cellular respiration happen to?
Everyone and it happens because our body needs energy.
What would happen if the nervous system of the human body stops working?
The end result would be death.
What would happen if the endocrine system fails?
Your body might not grow or mature properly.All body function would be deranged and death would occur .
What could happen to the body if the urinary system stopped working?
You would die, your bladder would explode and you would die
What system of your body do you get cellular respiration?
respitory, digestive, curculitory, & uranary
What system gets oxygen into the body so our cells can respire?
respiration
Where in the body does respiration happen?
Respiration occurs in the lungs, specifically in the alveoli where oxygen is taken in and carbon dioxide is eliminated from the bloodstream. The process involves the exchange of gases between the air we breathe and the blood.
