La histología es la ciencia que estudia los tejidos biológicos mediante el microscopio. Nos permite ver cómo se organizan las células para formar los órganos del cuerpo.

La célula se divide en dos compartimentos principales: el citoplasma (que contiene orgánulos e inclusiones) y el núcleo. Orgánulos Membranosos
Histology is the study of the organization and structure of tissues, which are groups of similar cells that perform specific functions. Tissues are the building blocks of organs, and understanding their structure and function is crucial for understanding how organs work and how diseases develop. Histology is an essential tool for diagnosing diseases, as it allows pathologists to examine tissue samples under a microscope to identify abnormalities.
The text organizes biological complexity into three primary levels: :
: Mucosa (epitelio, lámina propia, muscular de la mucosa), Submucosa (contiene el plexo de Meissner), Muscular Externa (capas circular interna y longitudinal externa con el plexo de Auerbach) y Serosa/Adventicia.
