Class 11 Zoology simulations · Structural Organisation in Animals

Epithelial tissues

Build sheets of epithelium from flat, cube-shaped or tall cells, with or without cilia.

Open the simulation

What to notice

Thin squamous cells suit diffusion; tall columnar cells hold more machinery for secretion and absorption.

Key relation

Simple (one layer) vs compound (many layers)

Try this

Switch to ciliated epithelium and watch the cilia beat in waves.

What you can change

• Epithelium: choose Squamous, Cuboidal, Columnar, Ciliated, Compound (stratified)
