What is destruction of lung parenchyma?
Abstract. The pathological hallmarks of chronic obstructive pulmonary disease (COPD) are inflammation of the small airways (bronchiolitis) and destruction of lung parenchyma (emphysema).
What is lung suppuration?
Pulmonary suppuration is defined as necrosis of the pulmonary parenchyma caused by microbial infection. Pulmonary suppuration may be primary or secondary based upon the presence or absence of common associated conditions.
What is crystallization of the lungs?
Silicosis is a lung disease. It usually happens in jobs where you breathe in dust that contains silica. That’s a tiny crystal found in sand, rock, or mineral ores like quartz. Over time, silica can build up in your lungs and breathing passages.
What is parenchymal of the lung?
The lung parenchyma is that portion of the lungs involved in gas exchange. The most prominent structure in this region is the alveolus (Figure 1). Each alveolus in the lung parenchyma opens directly into an alveolar duct or occasionally, in a limited number of species, into a respiratory bronchiole.
What is the disease that destroys the alveoli in your lungs?
Emphysema is a chronic lung condition in which the air sacs (alveoli) may be: Collapsed. Destroyed.
What is inflammation of the lung parenchyma?
Pneumonitis (noo-moe-NIE-tis) is a general term that refers to inflammation of lung tissue.
What is suppurative lesion?
Suppurative is a term used to describe a disease or condition in which a purulent exudate (pus) is formed and discharged.
What does purulent sputum always contain?
Purulent sputum contains pus, composed of white blood cells, cellular debris, dead tissue, serous fluid, and viscous liquid (mucus). Purulent sputum is typically yellow or green. It is seen in cases of pneumonia, bronchiectasis, lung abscess, or an advanced stage of bronchitis.
When lung tissue swells as a result of distention and loss of elasticity in the alveoli the condition is called?
Emphysema is a chronic lung condition in which the lungs’ natural airspaces, called alveoli, become larger but decrease in number. The tissue surrounding the alveoli loses elasticity so that the airspaces can no longer expand and shrink as usual.
What happens when you breathe silica dust?
Breathing in dust from silica-containing materials can lead to silicosis. Silica dust particles become trapped in lung tissue causing inflammation and scarring. The particles also reduce the lungs’ ability to take in oxygen. This condition is called silicosis.
What is included in the parenchyma?
Parenchyma is a type of tissue consists of cells that carry out an essential function. In botany (plant biology), parenchyma is the simple permanent ground tissues that form the bulk of the plant tissues, such as the soft part of leaves, fruit pulp, and other plant organs.
What does the parenchyma do?
Parenchyma forms the bulk of plant ground tissue, where they may be specialised to function in photosynthesis, storage, or transport. Parenchyma is integral to vascular tissue, where it provides a route of exchange for materials within and between the xylem and the phloem.
