Within the single system, individual organs, actions and co-ordinations are culminated to equate in the survival of humans. The respiratory system carries out many roles within the body; control of bodily pH, aid in speech production and olfaction

Section 1 : Anatomy and Physiology 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

trying to breathe, the epiglottis opens up and this will allow air to pass into our respiratory tract. Now whenever food does get into our respiratory tract, sometimes if we're eating too fast and we're not giving ourselves time to swallow, then food can get lodged down in the larynx or trachea and what happens usually is we begin to cough. Coughing is basically just pushing a big puff of air through the respiratory tract, which will hopefully pop out or dislodge that food particle. This is the

Bailey Kundinger Anatomy and Physiology II Friday February 17, 2017 Respiratory Syncytial Virus A mother brings their toddler in to the clinic, with what they think is a cold but a nurse wonders if the child could possibly have respiratory syncytial virus (RSV). A cold and RSV are a lot alike, in the way that they both may come across as “cold-like symptoms,” but this is not the case. Throughout this report one will find out what the differences between a common cold and RSV are, the signs and

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

Pathophysiology essay Lung compliance and its disorders Philippe Wöllenstein Study group 3052; Topic No.62 29.04.2015 ------------------------------------------------- Abstract ------------------------------------------------- The essay comprises an introduction explaining the term pulmonary compliance. The next section includes a definition and characteristics of the group of diseases-restrictive pulmonary disorders. Further on a short summary of restrictive lung diseases and especially

established initially by blood gas analysis. If the gradient between arterial and end tidal carbon dioxide partial pressures, P(a-ET)CO2 is stable with time, changes in treatment and clinical conditions, then PETCO2 can be reliably used to follow respiratory acid-base status and assist in the titration of hyperventilation therapy, at the same time decreases the expense and time involved in frequent ABG sampling. Several factors such as changes in body position, temperature and pulmonary blood flow

The conceptual overview, along with the experimental procedures are found in the NPB 101L Physiology Lab Manual 2nd Edition. More specifically, pages 55 to 63 provided a full insight to all the experiments in the respiratory lab. In addition, a list of required materials was given for every experiment. The authors of this lab manual were Erwin Bautista and Julia Korber. As for data acquisition, the BIOPAC software was used to collect and record data for all the trials. Furthermore, the teaching assistants

an equation that was more robust than the PaO2/FiO2 ratio in terms of less variation. The first chapter described two different types of oxygen indices and its use. The second chapter described the medical simulator in general and the Nottingham Physiology Simulator (NPS) in particular. In chapter three, we examined the variation of certain oxygen indices with changes in the following external physiological factors (FIO2, Hb, RQ, and VO2) without changing the pulmonary configuration status.
