Microvilli

Tiny, finger-like projections from the surface of some cells, increasing their surface area for absorption.

Goblet Cells

Specialized epithelial cells found in the respiratory and intestinal tracts, which secrete mucus to trap irritants and protect mucous membranes.

Columnar Epithelium

A type of epithelium that consists of single or multiple layers of column-shaped cells.

  • Recognize the various forms and properties of epithelial tissues, along with their distinct placements within the human anatomy.
  • Examine how epithelial tissues are functionally adapted to fulfill their distinctive roles in protection, absorption, and secretion.
