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.

1. This is part of the heart that is under the simple squamous epithelium, fibroelastic connective tissue and some smooth muscles. This is where modified cardiac muscles are located. 2. These are structures made up of dense irregular connective tissue that acts as insulator for the flow of electric current across the heart, surrounds the cardiac valves, and where the ventricular and atrial muscles are inserted. 3. These are modified cardiac muscle that are pale staining, smaller with fewer myofibrils...
