Question

What is an animal disease that involves the simple squamous epithelium?

Answer 1

Simple Squamous Epithelium: It is a single layer of flat cells in contact with basal lamina of epithelium.

• Basal lamina is one of the two layers of basement membrane which is made up of proteins and mucopolysaccharides separating epithelium from tissue.
• Function: It plays a role in transport of materials and absorption through Diffusion,Osmosis and Filtration process.
• Location: Blood Vessels (Inner lying of blood vessels to reduce friction for blood flow) and walls of Alveoli( for exchange of gases between Air and Blood)

DISEASE INVOLVING SIMPLE SQUAMOUS EPITHELIUM: Emphysema( in animals)is a condition where there is damage to the alveoli where there is difficulty in expelling air from the lungs as a result the body do not get sufficient amount of oxygen. They are classified into two types: 1.Alveolar Emphysema 2.Interstitial Emphysema

• The Walls of Alveoli are damaged in Emphysema leading to squamous metaplasia which is changes in the Squamous epithelium structure.
• The Emphysema is seen in both animals and Humans but the factors of causing are different.In animals,Emphysema is commonly seen in Dogs and the causes are Lung Trauma,Cancer,lung Parasites,Congenital Bronchial Hypoplasia.
