There are three parts to the process of respiration: ventilation, external respiration, and internal respiration. Ventilation is where the air from the outside environment flows into our body. When we inhale, we breathe fresh air into our lungs and when we exhale we release carbon dioxide from our lungs. Next is external respiration, where oxygen and carbon dioxide meet in the lungs. The gases then go opposite directions and disseminate between the blood stream and air sacs of the lungs. Oxygen first enters the air sacs of the lungs and then the bloodstream to be delivered throughout the whole body, Carbon dioxide leaves through the bloodstream and reaches the air sacs to be released from the body. Lastly is internal respiration, the process of carbon dioxide and oxygen interchanging at a cellular level. Oxygen is delivered to tissues upon leaving the bloodstream. As a result of the oxygen reaching the cells, it produces metabolism for the body’s cells and the waste product is carbon dioxide.
The first organ to come into contact with air, is the nasal cavity, in which current air is distributed through nares, these are openings in the nose that air passes within. Next in the cavity is what ...

...g infants and young children, which is the Respiratory Syncytial Virus (RSV). RSV is a genus pneumovirus, which is a part of the Paramyxoviridae family (McCarthy & Hall, 2003.) During most children’s first two years of life they will have become a recipient of one or more RSV infections (C. McCarthy, C. Hall, 2003.) The RSV infection is spread VIA secretions that are sent into the air when the individual coughs are leaves nasal secretions on a surface that another individual may touch. The incubation period for RSV infection is generally between 2 to 8 days (C. McCarthy, C. Hall, 2003.) Typical symptoms include a cough, nasal congestion, and a fever. Otitis media can occur as well and is common. While most cases of RSV do not require treatments or hospitalizations, some cases do, to prevent the recipient from great harm or even in some cases death.

- The human respiratory system is a series of organs responsible for taking in oxygen and expelling carbon dioxide. In terrestrial animals, this is accomplished by breathing. The human body needs oxygen to sustain itself. A complete lack of oxygen is known as anoxia and a decrease in oxygen is known as hypoxia. After four to six minutes brain cells without oxygen, brain cells are destroyed and an extended period of hypoxia leads to brain damage and ultimately death. In humans, the average rate of breathing is dependent upon age.... [tags: breathing, respiratory system, oxygen]

- The Respiratory System Anatomy has to do with the structure of the body, or how it is made. Physiology has to do with how it all works together. Just like a car, unless you know all of the parts, how they work individually, and also how they work together, you won 't know how to figure out what the source of the problem is, or how to fix it. One of the few systems in the body is the respiratory system. Each system has an important job in keeping the body functioning.... [tags: Respiratory system, Oxygen, Vertebrate trachea]

- The EB’s case study said the female patient is 50 years old with symptoms of fever, chills, congestion, three weeks of coughing, shortness of breath when walking. The study implies that the patient is now seeking medical advice due to vital signs recording and the noting of decreased breath sounds and wheezing. She denies smoking and not taking any chronic medication. Based on the subjective symptoms, it appears this patient has bronchitis, a type of chronic obstructive pulmonary disease, which is a respiratory disorder....

- Smoking and the Respiratory System Respiratory system is an important part of our body. It is responsible for gaseous exchange, external and internal respirations, which are some of the most important functions in our body. While it is important, the system is also really delicate. If it is exposed to many pollutants, it can lead to serious diseases or even death. Smoking is a perfect example of exposing to pollutants. Most people smoke because they think they look stylish and become addicted to it, which cause bigger health problems to their respiratory system as well as other body parts....

- Introduction The body’s respiratory system’s functionality is primarily simple. Starting with inhalation first, oxygen rich air enters either the nostrils where cilia filter out foreign particles such as dust. After these foreign particles are coughed or sneezed out of the airway, air then passes through the nasal cavity into the oropharynx. From here the air containing oxygen the body needs passes through the laryngopharynx to the larynx, which is the transitional point between the upper and lower airways, and is protected by the epiglottis....

- ... These filter out dust and bacteria and are captured by the mucus in the lining of the airway where it can be excreted. Two processes control diffusion, internal and external respiration. External respiration is the process by which oxygen is drawn into the lungs and carbon dioxide and water are breathed out, and takes place inside the lungs through diffusion. Internal respiration takes place at a cellular level, also occurs due to diffusion but transports the oxygen rich blood to the body’s tissues and organs whilst picking up the waste water and carbon dioxide for external respiration....

- The lungs are the main organs of the respiratory system. Their function is to regulate gas exchange. They are located in the thorax. They are connected to the trachea which conducts inhaled air through its tubular branches, called bronchi. The bronchi then divide into smaller and smaller branches (called bronchioles). The bronchioles eventually end in small air sacs called alveoli. It is in alveoli that occurs the gas exchange. Lungs are in contact with airway microorganisms and elements like tobacco....

- The simple act of breathing is often taken for granted. As an automated function sustaining life, most of us do not have to think about the act of breathing. However, for many others, respiratory diseases make this simple act thought consuming. Emphysema is one such disease taking away the ease, but instead inflicting labored breathing and a hope for a cure. Healthy lung tissue is predominately soft, elastic connective tissue, designed to slide easily over the thorax with each breath. The lungs are covered with visceral pleura which glide fluidly over the parietal pleura of the thoracic cavity thanks to the serous secretion of pleural fluid (Marieb, 2006, p....

Panacinar emphysema “generally is observed in patients with homozygous alpha1-antitrypsin (AAT) deficiency. In people who smoke, focal panacinar emphysema at the lung bases may accompany centriacinar emphysema” (Demirjian 1). The third type of emphysema is called paraseptal emphysema, also known as distal acinar emphysema. This type involves the distal airway structures, alveolar ducts, and alveolar sacs....

- Respiratory Acidosis and Respiratory Alkalosis is described as the abnormal conditions that come from imbalances in the pH of the blood which is caused by an excess of acid or alkali. Typically, these imbalances can be caused by many underlying conditions and or diseases. Normal blood pH levels in blood must be maintained within a narrow range of 7.35-7.45 to ensure that metabolic process is functioning properly and is producing the correct amount of oxygen to the tissues (Healthline.com, 2012)....
