Basic function of the lung
The lungs are a significant organ in the body. Lungs permit the breathing process. They allow oxygen into the body and also remove carbon dioxide. The lung is a soft organ that is protected by the ribcage. Two lungs are contained in the chest, a right and left lung for each side of the chest. They are further divided into lobes and segments and are mostly involved in the gas exchange at the alveolar level (Diaz-Medonza et al. 2013). Lungs are able to expand, when expanding air is drawn in, and bound back to their original position and size when air is leaving. Being able to execute this function depends on the control and balance present between ventilation, breathing mechanics, and vascular perfusion (Hazari et al. 2010). Oxygen is key for organisms because this is what provides energy and nutrients for the blood supply. Carbon dioxide is a waste product of the body which needs to be ridded.
Chronic Obstructive Pulmonary Disease (COPD)
A disease that occurs in the lungs is Chronic Obstructive Pulmonary Disease (COPD). It is considered a group of lung conditions which makes it difficult for the lungs to clear the air out. Symptons of this disease include shortness of breath, the feeling of fatigue or cough. COPD is also a disease used to describe someone with chronic bronchitis, emphysema, or even a combination of both conditions. This disease is at most of a higher risk when a person is a smoker. Along with smoking, other factors that can contribute to COPD is aging and sleep disturbances. In a majority of cases COPD is a weakening disease that coexist with sleep disturbances (Ohayon 2014). Difficulty breathing or night awakenings during sleep is commonl...

...in order to focus on the growth of pulmonary cells. It has been demonstrated that pulmonary cells can grow rapidly in vitro.
Future Research of COPD
Many Americans suffer from COPD, it is now ranked the forth leading disease to cause death (Croxton et al. 2002). A major way to prevent this disease is by being a non-smoker, but many people still continue to smoke cigarettes. Although smoking is a key factor in COPD, it is not the only thing causing this disease, this means that further research in risk factors should be looked into. Things such as discoveries, new experimental approaches, and techniques have been developed (Croxton et al. 2002). Developments such as these are significant in aiding the prevention and treatment of the disease. COPD is currently an enormous health burden, therefore the research progress on this disease is in urgent need.

- 1.1 Regenerative Medicine 1.1.1 Tissue Engineering Tissue engineering uses natural biology principles and engineering to develop materials that can be used to restore, maintain, improve or enhance natural regeneration of tissue function. Tissue engineering is a potential solution to help increase the length of life, alleviate the current shortage of donor tissue. On average, 2.2 million annual bone grafting procedures are carried out globally, with most using biological autograph tissue (Malak and Anderson, 2008)....

- Bone and Teeth Tissue Regeneration The ability to be able to regenerate bone tissue by tissue engineering may be the first method of regeneration to be successful. Researchers are constantly looking for solutions to reduce the amount of complications that accompany dentistry and/or orthopedic treatment of congenital anomalies, trauma, periodontitis, and other diseases (Alsberg et al. 2001). Though the common treatments may include autograph tissue (tissue that was taken from one part of the body and placed in another part of the same body) or artificial teeth, there are many complications that are associated with these types of treatments (Xiong 2002)....

- One of the most versatile and dynamic substances used by researchers and doctors is also the most ubiquitous: human tissue. Donated tissue samples are used many different ways, from basic study to advanced testing. Scientists can better understand the disease process by observing it at a cellular level. Drugs can also be tested and refined on tissue samples. Some of the more important areas of study include cancer, diabetes, liver disease, stroke and Alzheimer's disease. It is also used to help develop diagnostic tests, so that doctors can detect disease less invasively, during a routine office visit.... [tags: pharmacology, regeneration, future ]

- Epithelial-mesenchymal interactions mediate organogenesis, which results from the activation of complex gene networks. Early respiratory development arises from the foregut endoderm and gives rise to tracheal and lung progenitor cells. Recent studies have linked fibroblast growth factor, Wnt, and other signaling pathways to the initial stages of lung development. Cells respond to signaling proteins mainly though transcription factors that ultimately determine cell fate and pattern formation. Gain and loss-of-function studies have facilitated the identification and functionality of molecular components as part of development.... [tags: Biology, Lung]

- Lung cancer is a leading cause of death worldwide both in men and women. It accounts for nearly 1.2 million deaths per year. Over the last few years many advances have been made in the field of surgery, chemotherapy and radiations for treating this deadly cancer but they are unlikely to result in cure. Lung cancer is associated with very bad prognosis. So there is a dire need of developing novel therapeutic vaccines for improving prognosis of this disease Cancer therapeutic vaccines are designed to regulate the host tumour interactions in order to shift the balance from tumour acceptance to tumour control....

- Regeneration Process of Tissues When an injury is sustained, the body sets into motion various processes, which are needed to repair the damaged tissue. A Physical Therapist or Athletic Trainer can aid the natural repair processes of tissue by using various therapeutic modalities within an appropriate time shortly after an injury. This paper will discuss the physiological effects of therapeutic modalities and their relation to the regeneration process of tissues. A. The injury process The body's reaction to injury may be divided into two distinct parts.... [tags: Therapeutic Modalities Therapy Papers]

- Regeneration by Pat Barker The war in 'Regeneration' is explored 'back home'. Rather than portraying the war in terms of fighting on the frontline in the battlefields of France, Barker demonstrates the effects on the soldiers 'back home', both physically and mentally. The soldiers are those who have been injured, shell-shocked, or had a breakdown and are being treated with the intention of sending those who are able, back to France or at least resuming some kind of war duties. The war is explored, essentially in terms of the psychological effects of those who fought it.... [tags: Regeneration Pat Barker Essays]
