Since we are born, the very first thing we do is we breathe! Breathing feeds oxygen to each cell within the body through the lungs and expels out waste CO2 . However, we usually take our lung functions and breathing without any consideration . We don’t consider the importance of our lungs unless we experience breathing problems, and therefore the COVID-19 pandemic teaches us this! A lung capacity and volume are the entire amounts of air that hold your lungs during inspiration and expiration. Over time, as we age, our lung capacity and functions decrease. Smoking, pollution, and other health problems like asthma or chronic obstructive pulmonary disease (COPD) can make it worse. Though an individual unable to regulate the quantity of oxygen their lung can hold, lung exercises provide ways to assist your lungs become more efficient at managing airflow and oxygen levels.  You can increase the number of oxygen in your blood naturally. Some ways include: Open windows or get outside to br...

Breathing is central to life, because it permits human body to obtains the energy it has to sustain itself and its activities. But how does it work? Breathing uses chemical and mechanical processes to bring oxygen to every cell of the body and to get rid of carbon dioxide. Our body needs oxygen to obtain energy to fuel all our living processes. Carbon dioxide is a waste product of that process. The respiratory system, with its conduction and respiratory zones, brings air from the environment to the lungs and facilitates gas exchange both in the lungs and within the cells.    Our  body needs oxygen  to obtain energy to fuel all our living processes.
