Understanding Respiratory System

The respiration system is the process of supplying oxygen to the cells so that cells can metabolise energy. The main functions of the respiratory system are to maintain oxygen supply to cells, to remove water from the body, and to remove carbon dioxide from the body.

➢ Inhaled air enters the nasal cavity, where it is cleaned, warmed and humidified on its way through the pharynx.

The respiratory system is a complex organ structure of the human body anatomy, and the primary purpose of this system is to supply the blood with oxygen in order for the blood vessels to carry the precious gaseous element to all parts of the body to accomplish cell respiration. The respiratory system completes this important function of breathing throughout inspiration. In the breathing process inhaling oxygen is essential for cells to metabolize nutrients and carry out some other tasks, but it must occur simultaneously with exhaling when the carbon dioxide is excreted, this exchange of gases is the respiratory system's means of getting oxygen to the blood (McGowan, Jefferies & Turley, 2004).

The respiratory system consists of the lungs and air passages. The system functions to bring in air and extract oxygen and remove carbon dioxide*. The body can hold 4 to 6 minutes worth of oxygen so the respiratory system must work at all times to prevent death. There are multiple parts to the respiratory system for example, the nose has nostrils or nares. It contains a nasal septum which divides the nose into hollow spaces called nasal cavities. The nose filters the air with the mucus produced. Also located in the nose are the olfactory receptors, and nasolacrimal ducts. The sinuses which are resonating chambers of cavities located in the skull. A larger part of the respiratory system is the pharynx also known as the throat. It is located directly behind the nasal area, divided into three parts; nasopharynx(upper portion), Oropharynx(middle portion), Laryngopharynx (lower portion). The larynx also known as the “voice box” located between the trachea and pharynx. Trachea also known as the windpipe extends from the larynx to the center of the chest; its functions to carry air between the pharynx and bronchi. The bronchi function to carry air to the lungs. The right bronchus is more vertical, shorter, and wider compared to the left.Bronchi continue to branch off into smaller bronchioles, the smallest is called terminal bronchioles which deliver air to the alveoli. 500 million alveoli, which have a rich network of capillaries needed for exchange of oxygen and CO2( taken place

The respiratory system, also known as the ventilatory system, is a series of organs found in the human body. The system’s primary function is performing respiration – inhaling oxygen from the environment and exhaling carbon dioxide out of the body (K.M Zimmermann, 2016). Oxygen acts as fuel – without it, the body would be unable to function. Carbon dioxide, the by-product of this process, is breathed out as it is toxic to the human body when it builds up (A.M Helminstine, 2016).

Respiratory rate is a greater predictor of a deteriorating patient, and a predictor foe adverse patient outcomes. There is much discussion within the literature around the importance of accurate measurement of respiratory rate, registered nurses perception of respiratory rate compared to other vital signs and adverse patient outcomes and implications associated with respiratory dysfunction. This discussion is undertaken to gain a further understanding of the role of the Registered Nurse in assessing patients respiratory rate.

The respiratory system and the digestive system interrelate because the respiratory system takes the oxygen that it needs for the body from the outer side and brings it into the lungs and there it is diffused through the lungs into the blood stream. The circulatory system carries the oxygenated blood throughout the body in where the oxygen is exchanged for waste materials and the carbon dioxide is carried back to the lungs and let out of the atmosphere to exchange for the oxygen. The digestive system interrelates with the respiratory system because, the respiratory gives oxygen to the digestive system. The digestive system interrelates with the respiratory system because they both need energy to work When oxygen and glucose reacts together

The respiratory system is the process responsible for the transportation and exchange of gases into and out of the human body. As we breath in, oxygen in the air containing oxygen is drawn into the lungs through a series of air pipes known as the airway and into the lungs. As air is drawn into the lungs and waste gas excreted, it passes through the airway, first through the mouth or nose and through the pharynx, larynx and windpipe – also known as the trachea. At this point it then enters the lungs through the bronchi before finally reaching the air sacs known as alveoli. Within the lungs, through a process known as diffusion, the oxygen is transferred to the blood stream through the alveoli (air ducts) where it is then transported inside

The respiratory system is a series of organs in which is responsible for taking in oxygen and releasing carbon dioxide. The main organ in the respiratory is the lungs which helps with the prosses of exchanging gases as we breath. Red blood cells collect and use the oxygen to carry around the body to parts that need it. The body needs oxygen to survive because when without it, it would be fatal which is why the respiratory system is important.

The respiratory system is what allows the body to exchange gasses between the air and blood, and between blood and the body’s billions of cells. (Healthline, 2015) The respiratory system also filters, warms and humidifies the air you breathe in. This system helps the body maintain homeostasis, which is the balance of the many different internal elements in the body.

This is part of the respiratory system which refers to the process of oxygen and carbon dioxide moving between the lungs and blood. Within the alveoli, the exchange of gases takes place between the gases inside the alveoli and the blood. Due to the air in the alveoli having a much lower concentration of carbon dioxide.

Observe for rate, rhythm, breath volume, and any effort associated with breathing. Most resting adults breathe about 12 times per minute.

Despite its importance, respiration rates are being found to be documented less often that any other vital sign. . This may be due to inadequete understanding of the physiology of respiratory rate and the potential problems that an increased or decreased respiratory rate could mean. (Ansell, Meyer & Thompson 2014). Respiratory rate remains the only vital sign taken manually, without a machine, which could also contribute to why it is inconsistantly taken. Respiratory rate is a highly sensitive marker of patients’ conditions and of early signs of deterioration, and their assessment can help health practitioners detect subtle changes in patients’ physiology and reduce the risk of multi-organ damage, arrest or death. (Smith et al 2011, Cretikos

These 3 experiments offered an in-depth understanding to the respiratory system’s role in homeostatic regulation. Furthermore, it provided an insight to the relationship between the respiratory system and the central nervous system. Consequently, seen firsthand throughout the experiments, this system is one of the first responders when the body requires an accurate, and immediate response to changes involving internal, and external gas compositions.

The human respiratory system is a variety of organs responsible for taking in oxygen and releasing carbon dioxide. The respiratory insists of key parts, which are the lungs, the airway, and the muscles of respiration.
