Respiratory system

Ventilation Ventilation is the movement of air in and out of the lungs, also known as inspiration and expiration as previously stated. Respirations are controlled by the medulla oblongata in the brain. The medulla oblongata initiates the signal for the respiratory muscles to…

function involuntary, the anatomy is awe-inspiring. Every aspect has a purpose, and consequently the design of the tissue or organ system is the result of form following function. As a result, when an anatomical aspect deviates from its intended shape or composition, the effect can prove detrimental. This occurrence is especially caustic in regards to the respiratory system, which is paramount for staying alive. A prime example of how dangerous a divergence from the typical lung-layout can be is…

Cigarettes consist of many harmful chemicals. One of those chemicals is Nicotine which is a highly toxic substance that causes many respiratory diseases like respiratory muscle paralysis, it also negatively affects the central nervous system. Nevertheless, scientific researches proved that the concentration of Nicotine in cigarettes increased by 16% in the time period between 1998 and 2004 according to the Massachusetts department of public health. Since Nicotine is an addictive substance, this…

The process of oxygen and carbon dioxide moving in opposite directions across respiratory membranes is referred to as gas exchange. To extract energy from the sugars and acids in our body, oxygen is needed. During the process of extracting energy carbon dioxide is produced and the body must rid its self of this toxin. Movement of the cellular molecules in the human body in a manner that is not directional is called diffusion. Net diffusion occurs when there is a directed movement and…

technique, positioning, bodily systems involved, and type of patient monitoring in the OR, PACU and respiratory. Be sure to describe the type of wounds and type of healing. The shift assessment I preformed on the patient with end-stage COPD was very congruent with the expected findings. I noted bilateral crackles, diminished capillary perfusion, low oxygen saturation, and increased anterior-posterior diameter upon assessment. Due to the patient’s status, frequent respiratory assessments were a…

Air pollution is the primary reason of why many adults and children suffer from several respiratory illnesses. The outdoor air pollution is not only man-made but nature has a role in it. Millions of people die or are diagnosed with diseases that could be acute or chronic. There are ways to save lives with simple steps that could be impactful. It could be complicated because of all the political and economic value tied into it, but there is always a way to make change possible.…

Asthma affects the respiratory system where there is limited airflow into the lungs. Which certain substances trigger an asthma attack, resulting the airways to respond by tightening the muscles(the bronchioles). The process is called bronchoconstriction. An asthma attack is quite frightening. One may cough and have difficulty of breathing or feel a shortness of breath. They may breathe out and a wheezing or whistling sound may be heard. With the attack, it may result in people feeling fatigued…

in the body. When complications with infections occur regions of the lung can fill with fluid, also babies born premature can have underdeveloped lungs causing increased surface tension. These cause the lungs to remain closed, a disease called respiratory distress syndrome. The deformation of biological cells when exposed to different flow conditions is a problem. Surface tension on an air–liquid boundary creates liquid flows, which causes the lung to close due to the formation of a liquid…

Bordetella pertussis is a very contagious disease in the upper respiratory system. It is known to cause whopping cough, or pertussis, an acute respiratory infection marked by spasmodic cough episodes. It is caused by the bacterium, Bordetella pertussis, and attaches to the lining of the airways, humans are its only host. It is characterized by fits of coughing that are so severe that you can’t stop or catch your breath. Although people of all ages can become infected with this disease, it is…

Respiratory systems vary from species to species but the basic anatomy for Serpentes suborder is straightforward. The average Serpentes respiratory system has two external nares, two internal nares, and a nasal cavity. While Serpentes have a nose, their nose is only meant to be another pathway for respiration. They are not used to smell like a human nose is used for. Serpentes have a glottis that is a vertical slit because it is always closed. The glottis is situated right behind the tongue and…
