Emphysema is characterized by the destruction of alveolar walls, leading to the formation of larger, less efficient air spaces. Histologically, this is accompanied by the loss of elastic fibers, resulting in decreased lung elasticity and impaired airflow. Additionally, there may be an increase in inflammatory cells, such as macrophages, and a thickening of the bronchiolar walls. These changes contribute to the hallmark symptoms of reduced gas exchange and respiratory distress.
What else can I help you with?
What is a disease that destroys lung tissue and causes difficulty in breathing?
emphysema
What is a histological exam?
A histological exam is a microscopic examination of tissue samples to study their cellular composition and structure. It is commonly used in medicine to diagnose and characterize diseases, such as cancer, based on the appearance of the tissue under a microscope.
What is the meaning of emphysema?
A swelling produced by gas or air diffused in the cellular tissue.
What is a calyx in a breast tissue specimen?
In breast tissue specimens, a calyx is a grouping of ducts and lobules surrounded by fibrous tissue. It is a structural unit that is commonly seen in histological examination of breast tissue to assess its health and changes. Calyces are important for understanding breast anatomy and pathology.
Is emphysema a respiratory disease?
Yes. It is usually caused by the destruction of lung tissue from smoking.
Which animals are best used in histological experiments?
The main features of experimental ALI include histological evidence of tissue, lar measurements that best suit the experimental questions being addressed as animal studies frequently use young mice with no comorbidities.
What is the definition of tissue cutting?
Tissue cutting refers to the process of dividing or separating biological tissues with a sharp instrument, such as a scalpel or scissors, for various purposes like histological examination, medical procedures, or research studies.
Stretching of lung tissue caused by the alveoli becoming distended and losing elasticity occurs in?
emphysema
A thin stained slice of tissue mounted on a microscope is called?
A thin stained slice of tissue mounted on a microscope is called a histological slide. These slides are used to observe and examine tissue structures at a cellular level under a microscope.
How does emphysema damage the tissue?
air sacs Hope I helped! Ace that test :P
What is an adjective for tissue biology?
An appropriate adjective for tissue biology is "histological," which pertains to the study of the microscopic structure of tissues. This term encompasses the examination of tissue organization, cellular composition, and the interactions between different cell types within various biological systems.
Choose the answer that shows the correct order for the standard preparation of a histological specimen?
The standard preparation of a histological specimen typically involves the following steps: fixation to preserve the tissue structure, embedding in a supportive medium (usually paraffin), sectioning the tissue into thin slices using a microtome, and then staining the sections to enhance contrast and highlight specific cellular components. This sequence ensures that the tissue is adequately preserved, accessible for microscopic analysis, and visually distinct for examination.
