Functions of the Epithelial Tissue

  • Protection (skin)
  • Absorption (stomach)
  • Filtration and Excretion (kidneys)
  • Secretion (gland)
  • Sensory Perception (nerves)

  • Flat and scale-like

Simple Squamous: a single layer and flat, forms a solid layer of cells which line blood vessels and organs, filtration and diffusion

Stratified Squamous: multiple layers, thick and flat with waves, forms the epidermis, provides protection


  • Cube shaped

Simple Cuboidal: lines the ducts in the kidneys and glands, responsible for reabsorption and secretion, made of a single layer and is cube shaped

Stratified Cuboidal: multiple layers, thick and cube-shaped


  • Tall, elongated cells

Simple Columnar: are tall and elongated, one cell and is thick, lines the digestive tract, responsible for reabsorption and secretion

Stratified Columnar: multiple layers of cells, very rare, found in the pharynx and larynx

Pseudostratified Columnar: tall elongated cells with cilia, it lines the body's passage ways, secretion


Functions of the Connective Tissue

  • Connect, bind, and support structures
  • Protect/ cushion organs and tissues
  • The extracellular matrix can bear weight, stretch, and take abuse
  • Adipose insulates and stores fat while blood transports substances
  • Bones provide framework/protection

Types of Connective Tissue

Bone: support and protection for our body and organs, also needed for its mineral storage and blood cell production

Cartilage: 1.) Hyaline 2.) Elastic 3.) Fibrocartilage

Dense Connective: irregular, runs in many different directions

Loose Connective: Three types of loose connective tissue

1.) Areolar

2.) Adipose

3.) Reticular

Blood: has a matrix, blood/plasma, that surrounds the

Types of Muscular Tissue

Skeletal Tissue: attaches muscle to bone, body movements voluntary, and
long strands

Smooth Tissue : along organ walls and blood vessel walls, moves blood, throughout body, involuntary,
and striated

Cardiac Tissue: found in the heart, synchronizes heart beat, involuntary, and branch-like


Anatomy and Physiology of the Nervous Tissue

Nervous tissue is found in the brain, spinal cord, and the nerves. Its main function is to generate and transmit nerve impulses to and from body organs through neurons. Some special cells, referred to as neuroglia, provide support, insulation, and protection to the neurons.

Nervous tissue is web-like.

Best Type of Tissue

The Nervous System

The Nervous System is the best type of tissue and the most important to our body. The nervous system is responsible for sending signals throughout the body to organs through nerves. This means that the nervous system is responsible for the overall control of our bodies. The nervous system is also needed for all other types of tissue to function. The signal for the other tissues must first be transferred through the nervous system in the body.
