Essays on Parenchyma

COPD is a medical condition that is characterized by alteration in lung parenchyma, bronchitis, emphysema and narrowing of the respiratory passages. It occurs as a consequence to chronic inflammation reaction involving the respiratory tract. The mucous secretion and fibrosis associated with chronic inflammation, can cause blockage and narrowing of the airway. Bronchitis refers to inflammation of the inner lining of the lung, while, emphysema is a clinical condition that occurs following the long term destruction of lung parenchyma. Bronchitis and emphysema are both characteristic features of COPD. Destruction of lung parenchyma causes loss of alveolar attachment and decreases the ...

A Proper understanding of the pathophysiology of diseases and conditions is essential in their treatment as well as management. Every disease has a way of affecting the normal functioning of the body. Some disorders attack the whole body while others affect specific organs. Therefore, it is crucial to study the pathophysiology of diseases. It is also essential to understand the relationship between related diseases. This helps in understanding the interactions between the diseases. This paper is set to examine the pathophysiology of pneumonia, hypoxemia, as well as thyroid cancer. Additionally, the paper analyses the relationship between these diseases.

Pathophysiology of Pneumonia

Compare and contrast the structure and function of the three simple tissue types: parenchyma, collenchyma, and sclerenchyma.

Parenchyma cells refer to plant cells in the leaf that are usually alive at maturity. They have cell walls that are thin and flexible. They generally have a central vacuole that is large. They have a polyhedral arrangement. They are involved in carrying out photosynthesis, storage functions, and other metabolic functions. Most of these cells have the potential to undergo differentiation generating other cell types in certain conditions. For instance, when the plant is injured and there is a need for repairing and replacing organs. Their large central vacuoles enable them to store water, regulate intake of ions and ...

Liver is the largest ‘gland’ of the digestive system. It is located right under the dome of the diaphragm, coated by the capsule. It is distinguished the liver’s convex upper surface adjacent to the diaphragm, and a lower, downwardly facing and in contact with the back and abdominal organs. On the part of the upper surface of the liver it can be seen its right and left lobes, the boundary of which is the crescent liver ligament. To the lower surface of the right lobe there is a gallbladder, close to the deep groove of the liver there ...

Introduction

Pulmonary edema (PE) is characterized by the accumulation of fluid in the parenchyma and air spaces of the lungs. Most often PE is associated with respiratory failure and impaired gas exchange. Globally, PE is known to be characterized by two major factors, the first is associated with the injury of the lung parenchyma which is termed as non-cardiogenic pulmonary edema. The second is associated with the failure of the left ventricle of the heart to release blood from the pulmonary circulation within the system and is termed as cardiogenic pulmonary edema (Glaus, Schellenberg , and Lang. 2010). The major cause ...

Introduction

Approximately 2.5 million individuals in the United States contract pneumonia annually, and 55,000 of those individuals die as a result. In fact, pneumonia was the eighth prominent cause of morbidity and is the number one communicable disease in the United States. Pneumonia is the leading deadly hospital-contracted disease and contributes to a sizable amount of deaths in unindustrialized countries as well. It is a grave illness that can impact individuals in all age groups, but it is especially serious in adolescents, the elderly population, and in people with fundamental medical issues such as ischemia, low blood sugar, and ...

Smoke Inhalation

Smoke inhalational injury is the most prominent cause of death in patients involved in fire accidents. It has been said that prevalence of death due to inhalation of smoke and other noxious substances stands between 60 and 80% in the United States. (Lafferty, 2010). Smoke inhalational injury remains a serious threat to the health of victims of explosions, house fires and other forms of fire disaster. (Murakami & Traber, 2002) In the Pathophysiology of acute and chronic Smoke Inhalational Injury, three mechanisms readily come into mind. They include thermal damage of the lung parenchyma, pulmonary irritation and asphyxiation. (Lafferty, 2010). ...
