Causes Of Visceral Pleura

Oxygen aids in carrying out several cellular processes of energy transformation for life. In many processes, oxygen is consumed when nutrients, such as protein, carbohydrates, or fats are oxidized, and carbon dioxide is produced as the gaseous waste. Respiration is the process by which oxygen is taken from the environment, delivered to the cells, utilized by those cells, and where carbon dioxide is is produced and delivered to the lungs to be excreted. There are three different categories of respiration;

presence of this airway obstruction causes edema and mucus secretion. When there is an increased sensitivity to irritating stimuli, bronchoconstriction occurs leading to hyperplasia of smooth muscle, hyper secretion and dis-modeling of the epithelium. Anatomy of the Lung The lung is located in the chest as part of the respiratory system. The respiratory systems consists of the trachea, bronchi, lung, mediastinum, pleura and diaphragm. The left lung has two

Asthma is a common, chronic, respiratory disease that causes the airways of the lungs to swell and narrow. Structurally, the respiratory system consists of two parts. The upper respiratory system includes the nose, pharynx, and associated structures. The pharynx is a muscular tube lined by a mucus membrane that starts at the internal nares and extends to the larynx. The lower respiratory system includes the larynx, trachea, bronchi, and the lungs. The larynx is a passageway connecting the laryngopharynx

and can cause varying degrees of symptoms and complications. Patients with pleural effusion are ripe for diagnostic radiography, as it is often the best source of information about their condition and it’s severity. Pleural effusion is defined by Liz Allibone as “an abnormal collection of fluid in the pleural space caused by a variety of mechanisms.” The pleural space is a cavity between the chest wall and the lung that consists of two layers, the parietal pleura and the visceral pleura. These two

Describe the gross anatomy of the lungs; And define pneumonia and outline briefly the etiology, pathophysiology and radiographic appearances of alveolar pneumonia. 1. Introduction The lungs are the essential organs of respiration; they are two in number and are placed one on either side within the thorax, separated from each other by the heart. The substance of the lung is light, spongy and porous. The surface is smooth, shining and marked into numerous areas, indicating the lobules of the organs

person feeling as though something is obstructing their airways. They cough to try to help clear their airways. The wheezing a person experiences comes from when the bronchioles are constricted and it makes it difficult to breathe the closed up airways causes a whistling noise occur when you breathe out. Chest tightness during asthma happens because in the lungs there are no nociceptors. The lack of

the serous pericardium, contains two inner layers. The lining of the fibrous pericardium called the parietal pericardium and usually measures 2mm in thickness. The layer lining the heart organ is known as visceral pericardium; also the epicardium. And the cavity between the parietal and visceral pericardium, filled with serous pericardial fluid,that helps reduce friction as the heart contracts. The pericardium provides protection in an enclosed lubricated space for the contracting heart. But, the

of the pigment in both abnormal and normal tissue, suggests that its presence is not significant. Based on the preceding observations, it was concluded that suppurative pneumonia is affecting the entirety of the lung, including the parenchyma and pleura. In tissues other than pulmonary tissues, the presence of macrophages would indicate chronic or sub-acute inflammation. The lung, however, has a large macrophage reservoir, that is mobilized much more rapidly than in other tissues. The differentiation

The circulatory system is made up of vessels and pumps that helps transport nutrients and oxygen throughout the body. The vessels and pumps help circulate the blood through the structures of the body systems. The heart is at the centre of the circulatory system. The heart helps pump blood throughout the whole body, and the blood goes back to the heart in a circular motion going round in a circle but it goes around the body and body systems. The cells within the body get their nutrients from both

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. 430). During inhalation, the lungs expand with air, similar to filling a balloon.
