Tissues are groups of cells that are similar in structure and function. There are four different types of tissues: Epithelium, Connective, Nervous, and Muscle. Tissues are organizes into organs like the heart, kidneys, and lungs. They determine the organs structure.

Epithelial cells fit closely together to form continuous sheets. The membranes always have one free unattached surface or edge. The lower surface of the tissue rests on a basement membrane. They have no blood supply of their own, so they depend on diffusion from the capillaries. They regenerate themselves.

Simple Squamous Simple Cuboidal Simple Columnar Stratified Squamous Pseudostratified Columnar Transtional

A single layer of thin squamous cells resting on a basement membrane. Cells fit closely together and form membranes where filtration or exchange of substances rapid diffusion occurs. Located in the air sacs of the lungs, also in the walls of the capillaries. Also forms serous membranes in the ventral body cavity.

It is one layer of cuboidal cells resting on a basement membrane. It is found in glands and their ducts like the salivary glands and pancreas. Also forms the walls of the kidney tubules and covers the surface of the ovaries.

Made up of a single layer of tall cells that fit closely together. Lines the entire length of the digestive tract from stomach to anus. Goblet cells are seen in this type of epithelium, they produce a lubricating mucus.

Is the most common stratified epithelium in the body. Consists of several layers of cells. Found in sights where it receives a good amount of abuse or friction like the esophagus, mouth, and outer portion of the skin.

Rest on a basement membrane and consist of different sizes of cells and nuclei appear at different heights above the basement membrane. Mainly functions in absorption and secretion. Lines the respiratory tract.

Highly modified, stratified squamous epithelium that forms the lining of a few organs It’s found in the urinary bladder, the ureters, and part of the urethra. In the tissue when its stretched out, the cells of the basal layer are cuboidal or columnar. If not stretched out, the cells are more rounded and domelike.

Bone Blood Cartilage Dense Loose/Areolar Adipose

Bone is composed of bone cells sitting in cavities called lacunae and layers of a very hard matrix that contains calcium salts in addition to large numbers of collagen fibers. Its rocklike hardness allow it the ability to protect and support other body organs.

Consists of blood cells surrounded by a nonliving fluid matrix called blood plasma. Blood is the transport vehicle for the cardiovascular system, carrying nutrients, wastes, respiratory gases, and many other substances throughout the body.

Cartilage It is a firm tissue but is softer and much more flexible than bone. A connective tissue found in many areas of the body including.

Dense Forms strong, rope-like structures such as tendons and ligaments. Dense connective tissue also make up the lower layers of the skin.

Loose/Areolar and Adipose These include areolar and adipose. Areolar and adipose are the most abundant types and these are typically found together in most body locales where blood vessels, nerves, ducts, and other structures are passing through tissues.

Muscle Skeletal Cardiac Smooth

Skeletal Most skeletal muscles are attached to bones by bundles of collagen fibers known as tendons. The skeletal muscle is also voluntary control.

Cardiac Is involuntary and is found on the walls and foundation of the heart.

Smooth Muscle tissue in which the contractile fibrils are not highly ordered. Not under voluntary control. Usually found in internal organs.

Nervous Tissue Nervous tissue is the main component of the two parts of the nervous system. It is found in he brain and spinal cord of the central nervous system, and the branching peripheral nerves of the peripheral nervous system, which regulates and controls bodily functions and activity.

Ulcer- open sore in the lining of the stomach Pleurisy- inflammation of lining of lungs and chest Peritonitis- inflammation of peritoneum, lining of inner wall of abdomen rheumatoid arthritis- persistent inflammation of synovial joints Carcinoma- cancer arising in epithelial tissue Sarcoma- cancer arising in striated muscle, cartilage, or bone
