Epithelial Tissue
This tissue is the Squamous Epithelium and is classified by cell arrangement, simple and stratified squamous. Simple squamous is one cell thick and forms a solid layer of cells that lines blood vessels and organs. Its function is to filtrate and diffuse. Stratified Squamous is multiple layers, forms the epidermis and functions in protection.

This tissue is the Cubiodal Epithelium. Simple Cuboidal is one cell thick, lines ducts in kidney and glands and functions with reabsorption and secretion. Stratified Cuboidal is more than one layer and it is very rare in sweat glands and salivary glands.

This tissue is the Columnar Epithelium. The simple columnar is one cell thick, lines the digestive tract and functions with reabsorption and secretion. The stratified columnar is multiple layers and is rare in pharynx and larynx. Pseudostratified Columnar appears stratified but is a single layer, usually ciliated and is found in lining air passages and reproductive tubes. It functions in secretion and cilia aids with movement.

This tissue is the Transitional Epithelium, it is found in bladder, urethra and the ureters of urinary tract. It stretches from stratified appearance to squamous and cells are very large.

Connective Tissue
There are five tissue types: bone, cartilage, dense, loose, and blood. Bone tissue is the hardest type, tree ring like appearance, supports and protects, stores minerals, and produces blood cells. Cartilage has strength and flexibility and resists wear. Dense tissue has collagen fibers which are the main matrix and splits into dense regular and irregular. Loose tissue is split into 3 types: Areolar, Adipose and Reticular Tissue. Their function is to cushion and hold organs together, store energy and protects insulates, and provides internal supporting framework for organs. Blood is surrounded by matrix called blood plasma. Blood carries nutrients, wastes, gases and other substances throughout the body.

Muscle Tissue
There are 3 different types of muscles: skeletal, smooth and cardiac. Skeletal tissue is a large body muscles, muscle bundles attach to bones for movement. Smooth tissue has organ and blood vessel walls and moves blood, food and waste. Cardiac tissue has heart walls and is involuntary. It deals with the contraction of the heart beat.

Nervous Tissue
The nervous tissue is located in the brain, spinal cord and nerves. The nervous system generates and transmits nerve impulses to and from body organs. It also supports, insulates and protect neurons.

I believe the best type of tissue for it's location and function in the body is the nervous tissue. Without the nervous tissue, our body wouldn't be able to function. For example, our brain wouldn't allow us to think and send signals.
