Respiratory system – all you need to know about it

     The human body is a complex machine, driven by multiple systems, complicated and fascinating at the same time. Each has its role but interacts with each other so that if a problem occurs at one, the other will start to give warning signals. One of these complex systems is the respiratory system, which assures us the necessary oxygen intake by our body as needed and removes carbon dioxide resulting from oxidation. Human respiratory device is formed of two types of organs, lung and airways, the latter being represented by the pharynx, trachea, larynx, bronchial and nasal cavity. The airways have the role of leading the air to the lungs and back, before purified, moist and warm.


    Each component of the respiratory system, is responsible for a task, namely, the the air we breathe, go through the nasal cavity, which heats the air, it is moistened and filtered and then  sends it to the pharynx, larynx, trachea, bronchi, alveolar sacs and in finally reaches the lungs. Respiratory function is ensured by two areas of the brainstem namely Varolio’s deck and medulla.

    Breathing process, occurs in two stages: pulmonary respiration and cellular respiration. During pulmonary respiration, air flows into the lungs and then out in a cycle which is repeated approximately 16 times per minute for a human at rest. This rhythm is more intense in women and in people who practice sport. Breathing, is an involuntary act and it is important to know that the lungs do not have muscles, they just passively follow the chest movements. Specifically, while we inhale, the chest expands due to respiratory muscle contraction. In that moment, the movement of the ribs, push sternum forward and lungs fill with air. Once you exhale, relax muscles and lungs decreases its volume in parallel with that of the ribcage.


    But what exactly does the respiratory system and what happens during the breathing process? More accurate, when we breathe, the air that reaches our lungs, lose oxygen and is enriched in water vapor and carbon dioxide. The exchange is made even into the lungs, where carbon dioxide in the blood, go through capillaries and alveoli walls, and later is exhaled. The oxygen from inhalation, reaches the alveoli, throughput capillary walls and lead to the blood, and to the organs of the body.

    A system as complex as the respiratory system, often encounter health problems. The most common cause respiratory disease occurrence, are infections, which is understandable when you consider that our respiratory system acts as a filter for the human body and is always exposed to germs, bacteria and viruses existing in the air. With so many risk factors, how to keep our respiratory system health? We can start by giving up smoking, active smoking and passive especially because non-smokers that are inhaling cigarette smoke in the rooms, are more affected than those who actively smoke. Then, it is highly recommended to do a daily routine of sports and not least, to control the quality of the air we breathe. As hygiene items that keep us constantly clean nasal passages, we can choose a neti pot. It help us to irrigate the nasal passages with saline fluid, while ensuring that our filtration system is operating at full capacity.
