tissue: how connective.

tissues are made up of cells. they have four different types: epitheal, connective, muscle, and nervous. they are given different work to do and at the same time, they were as complicated as the cells themselves.

epitheal tissue covers many of the parts of the body and packed tightly together. it serves as protection from any foreign body that might go in our body. it can be identified in four shapes: squamous or flat/scale-like, cuboidal or cube-shaped, columnar or column-like shaped, and transitional or stretchy and variably shaped. also, it can be identified through two arrangements: stratified or several-layer arrangement, or simple or single-layer and same cell type arrangement.

next is the connective tissue. connective tissues are the most common of the tissues and is found throughout the body more than any form. it hold things together and provide structure and support. there are three types of connective tissues: areolar, adipose and dense connective tissues. areolar tissues are fine, delicate web of loosely connective tissue. then, adipose tissues are used for proper funtioning and an example is fat. lastly, dense connective tissue forms a protective barriers for protection. an example is skin.

after the two, we have muscle tissues. muscle tissues are responsible for movement by and in the body. there are three types of muscle tissues. first is the skeletal tissue which is attached to the bones. then, the second is the cardiac muscle. cardiac muscles are found in the walls of the heart. and last is the smooth muscle which forms the walls of hollow organs.

last type is the nervous tissue which acts as messenger of the body. it has two types: neurons, and glia. neurons are conductors of information and glia is the support by holding the neurons in place.
