Importance of Oxygen in the Human Body
Miscellanea / / August 08, 2023
He oxygen In the human body it has a fundamental role by allowing the generation of energy at the cellular level. Thus, the oxygen plays a vital role in the development of life for most living beings, including in this case human being. Such is the importance of this gas that without it the appearance of complex life on the face of the earth would have been impossible; In this sense, it should be noted that there are some bacteria that can survive without it, but these are very simple life forms compared to multicellular organisms.
Cells require energy for their maintenance and development, energy obtained from the combination of different chemical substances with the oxygen that is breathed However, the energy obtained from these processes can only be maintained for a short time at the cellular level, that is, it is used almost immediately. This circumstance means that you must continually enter oxygen to the cells and therefore must continuously enter oxygen to the human body (and to the body of other
animals). Thus, breathing from the lungs guarantees that this continuous renewal of the gas is carried out in a systematic way; in the event that it were hindered by any circumstance, the most likely result would be death.Once he oxygen enters the lungs, it comes into contact with the blood and begins its journey through it to reach every cell in the body. There are blood vessels specifically dedicated to transporting blood rich in oxygen and other blood vessels that specialize in transporting blood poor in this element. Given the importance of this mechanism, of this process to supply every corner of the human body, it is understandable that in this sense there is an automatic behavior, independent of the will human; in this way, both breathing and blood pumping are carried out involuntarily.
In some specific circumstances we can experience the difficulty represented by the lack of oxygen. A clear example of this situation occurs when we carry out a exercise quite prolonged and intense physical. In these cases we will experience a need for it, a need that will make us shake and breathe faster and deeper. This phenomenon is mainly explained by the fact that the body requires a greater amount of energy to perform these activities, amount of energy that has its correlate in a greater amount of oxygen.
