Respiratory physiology

they should be. The respiratory system, the system that brings oxygen into your body and delivers it to the blood to be sent around for everything else to use. Breathing out seems like a simple task but it takes many different anatomical parts of your body and physiology to get the oxygen where it needs to go. There is also pathophysiology that will play a role in the system and the way that things may go wrong and oxygen may not get where it needs to be. Anatomy and Physiology of the Upper…

decreases progressively from wholly aquatic, to intertidal, to land species; and is greater in young crabs than in older crabs. Often the gills are enclosed in protective chambers, and ventilation is provided by specialized appendages that create the respiratory current. As in cephalopod mollusks, oxygen utilization is relatively high—up to 70 percent of the oxygen is extracted from the water passing over the gills in the European crayfish Astacus. A decrease in the partial pressure of oxygen in…

Respiratory Therapy began to enter the medical field in the early 1940s. Fast forward a few years and Respiratory Care still remains a relatively new field in the medical industry. Almost all fifty states now require a license or some other form of “other legal credentialing law governing the profession of respiratory care” (Weilacher). A Respiratory therapist by definition “treats people with health care issues affecting the cardiopulmonary system such as asthma, emphysema, pneumonia,…

Other prevalent lung illnesses in the United States are asthma, pneumonia, and ARDS, which all correlate with the concept of gas exchange. In each phase in the continuum of healthcare, nurses will be faced with a patient who is diagnosed with a respiratory illness or disease. Therefore, nurses play a vital role in health promotion and prevention in patients who are at risk for these problems. There is a wide range of evidence-based research available for nurses and health care professionals to…

The Upper Respiratory Tract The human respiratory system involves complex organization of structural and defense mechanisms for the inhalation and exhalation of gases. The primary function of the respiratory system is to breathe air, provide oxygen to the bloodstream, and expel carbon dioxide. The respiratory system also provides transport of respiratory gases, internal respiration, pulmonary ventilation, and external respiration. There are two zones of the respiratory system, the conducting…

use of a respiratory and circulatory system (Harris-Haller, 226). The respiratory system includes the lungs, and the cardiovascular system includes the heart. The evolution of the heart started from a two-chambered heart of a fish to a four-chambered heart in mammals (Harris-Haller, 229). The purpose of the experiment is to study the cardiopulmonary function of humans. Collecting data from a spirometry, electrocardiogram, blood pressure, pulse, and respiratory rate, the anatomy and physiology of…

Respiratory Syncytial Virus – RSV Anatomical & Physiological Influences Causes RSV more frequently effects infants but can affect adults. Infants who have had RSV have an increase frequency of wheezing. Air enters the respiratory tract through the nose or mouth and then either enters the nasopharynx, or oropharynx respectively. Continuing through the laryngopharynx to trachea, which divides at the carina to form the left and right main bronchus. In each lung the bronchus divide into the…

Our bodies maintain many complex systems in order to have a consistent internal environment to achieve homeostasis. The lungs which are part of the respiratory system play a crucial role in homeostasis by controlling our breathing. The lungs provide the appropriate interface for gas exchange to occur, this includes the delivery of oxygen to the blood and the removal of carbon dioxide carried in the blood to the alveoli which is then expired out of the body. The removal of carbon dioxide also…

The respiratory system is concerned with the exchange of water and carbon dioxide, the control of body fluid, the control of pH, and particularly the maintenance of homeostasis. Going into this lab, I wanted to observe the different parts of respiratory physiology and determine their purpose in being able to maintain homeostasis in the body. Through this lab I learned about lung capacity, or the amount of air my lungs can carry during different stages, such as inspiratory reserve volume,…

However, the elimination of CO2 is reliant upon alveolar ventilation. Over an extended period of time, this build up of CO2 will result in an uncompensated respiratory acidosis (Frumin et al., 1959). One potential side effect of delivering high levels of oxygen to the apneic patient is the resultant washout of nitrogen from the respiratory system, which is needed to prevent alveolar collapse. In order for apneic oxygenation to be effective, the alveoli must be patent, with minimal atelectasis…
