Connective Tissue

Connective tissue connects, binds and supports structures, such as tendons and ligaments. It wraps around organs to protect and cushion them. The extracellular matrix can bear weight, stretch and take abuse. It insulates and fills space as well as stores fat. Blood functions to transport nutrients and other substances throughout the body. There are different types of connective tissue: bone, cartilage, muslce, nervous, and blood. You have dense regular and dense irregular connective tissue. Dense regular connective tissue are regularly arranged bundles packed with fibers running the same way in one direction. Dense irregular connective tissue is irregularly arranged bundles with fibers running all directions. There are also three types of loose connective tissue. Areolar connective tissue has a loose arrangement of cells and fibers. It cushions organs and holds them together, and is mostly empty space. Adipose tissue appears empty when you look at it under a microscope because oil fills most of enlarged nucleus. This tissue functions to protect and insulate. Reticular connective tissue has a delicate network of fibers and cells. It provides internal supporting framework for lymphoid organs. Therefore, connective tissue is found throughout the body. It is everywhere.
