The Golgi apparatus is a series of closely opposed, flattened membranous sacs that are slightly curved, forming a cup-shaped structure (Figure 3-13). Most cells have a single Golgi apparatus located near the nucleus, although some cells may have several. Associated with

PART ONE Basic Cell Functions
Structure: Series of cup-shaped, closely opposed, flattened, membranous sacs; associated with numerous vesicles. Generally, a single Golgi apparatus is located in the central portion of a cell near its nucleus.
Function: Concentrates, modifies, and sorts proteins arriving from the granular endoplasmic reticulum prior to their distribution, by way of the Golgi vesicles, to other organelles or their secretion from cell.

This ebook provides an introductory explanation of the workings of the human body, with an effort to draw connections between the body systems and explain their interdependencies. A framework for the book is homeostasis and how the body maintains balance within each system. This is intended as a first introduction to physiology for a college-level course.
