Why Do We ALL Need Oxygen In Order To Survive?
Oxygen is one of the main sources of energy in a human and animal body. In order for humans to have the ability to do procedures essential to an everyday, such as walking, thinking, and laughing we need to breathe in oxygen. It gives humans life because without it the human body would not be able to live for any more than 10 minutes. Oxygen enters the human body and has to reach the blood cells to supply the body with the amount of oxygen it needs. There have also been studies that show if you breathe in oxygen when prescribed it leads to a longer and better quality filled life. [1]
Cellular Respiration is the process in which glucose is broken down which helps ATP (Adenosine Triphosphate) to occur in the mitochondria, releasing energy.
Cellular Respiration Formula:
C6H12O6 + O2 -> H2O + CO2
What Does Respiration Mean?
Respiration is a term for the exchange of oxygen when you inhale, inspiration, to carbon dioxide when you exhale, expiration. Carbon dioxide we exhale is a waste gas that includes the combination of carbon and oxygen during one of the processes in energy-making in a human body. [2]
How Does A Black Widow Spider "Breathe"?
The Black Widow Spider is contain lungs called "book lungs". A book lung contains several soft plates called lamellae which are peg-like structured to prevent them from collapsing . Both oxygen and carbon dioxide are carried in the spiders hemolymph, a liquid in arthropods and is similar to cells that make the blood in spiders, which shows that gas exchange is done in the spider's hemolyphm. Oxygen in the air passes in between the lamellae where it diffuses through the tissue to get to the blood. The book lungs are very unique because of their ability to widen or shrink the lamellae to the oxygen necessities in order to create energy in a spider.[3][4]
