INTRODUCTION TO
HISTOLOGY
Our Lady of Fatima University
,Histology - study of the tissues of the body and
how these tissues are arranged to constitute organs.
Tissues have two interacting components:
a. cells
b. extracellular matrix (ECM).
ECM - supports the cells and contains the fluid
transporting nutrients to the cells, and carrying
away their wastes and secretory products.
Cells produce the ECM locally and are in turn
strongly influenced by matrix molecules.
, HISTOLOGY
2 interacting components
1. Cell: basic unit of life
2. Extracellular matrix (ECM)
• organized and form complex structures that
surround the cells (eq. Collagen fibrils and
basement membrane)
- mechanical support of the cell
- transport nutrients
- carry away metabolites and secretory
products
