  • Front
  • Back
Single layer of flattened or thin cells. Connect like floor tiles. Nuclei are usually broad and thin
Diffusion/ filtration.
Lines the air sacks (alveoli ) of the longs walls of capillaries , blood and lymph vessels, covers membranes that line body cavities. Simple squamous is thin and easily damaged.
Simple squamous
Single layer cub shaped cells centrally located, spherical nuclei
Tubular secreation / tubular respiration: in the gland it secretes glandular products.
Lines the follicles of the thyroid gland, covers the ovaries, kidneys tubules and ducts of certain glands.
Simple cuboidal epithelium
Single layer elongated cells whose nuclei are usually about the same level, near the basement membrane simple columnar cells , specialized for absorption , often have tiny , cylindrical processes extending from their free surface.
Thick tissue enables it to protect underlying tissue secretes digestive fluids and absorbs nutrients from digested fluids.
Lines the uterus, portions of the digestive tract, stomach and small intestines
Simple columnar epithelium
Appear stratified or layered , but are not! A layered affect occurs because the nuclei are at two or more levels in a row of aligned cells.(single layer elongated cells)
Protection, secretion movement of mucus and substance. The mucus- covered linings are sticky and trap dust and microorganisms that enter with the air. The cilia move the mucus and its captured particles and out of the airways,
Linings of the respiratory sysystem.
Pseudostratifed columnar epithelium
Many layers of cells making the tissue relatively thick. Cells nearest the free surface are flattened the most, whereas those in the deep layers , were cell division occurs, are cuboidal or columanar.As new cells grow he old ones are pushed father and father outward, and become flattened.

“Keratinazation “– produces a covering of dry tough protective material that prevents water and other substances from escaping from the underlying tissue and blocks chemicals and microorganisms from entering
Outer layer of the skin, lining oral, vagina and anal cavity, esophagus. In these parts the tissue is not keratinized: it stays soft and moist, and cells on its free surfaces remain alive.
Stratified squamous epithelium
Consist of several layers of cells. The superficial cells are elongated, whereas the basal layers consist of cube shaped cells.
Projection, secretion
Part of the male urethra and in parts of the pharynx.
Several layers of cuboidal cells, when the organ is distended the tissue streaches , and the physical relationships among the cells change. While distended the tissue appears to contain only a few layers of cells
Forms barrier that helps prevent the contents of the urinary track from diffusing back into the internal environment.
Inner lining of the urinary bladder, lines the ureters and part of the urethra.
Transitional epithelium-
Single epithelial cell (unicellular) , such as mucus secreting goblet cell) or multi-cellular forms can be structurally subdivided into two groups- simple and compound glands. Simple gland communicates with the surface by means of duct that does not have branches before reaching the glandular cells or secretory portion. Glands that consist of epithelial lined tubes are called tubular glands; those whose terminal portion from saclike dilations are called alveolar glands
Secretion substance into ducts or body fluids, such cells are usually found within columnar or cuboidal epithelium, and one or more of these cells constitutes a gland.
Salivary glands sweat glands, endocrine glands.
Glandular epithelium-
Cells in fluid- gel matrix contain many collagenous and elastic fibers.
Binds organs holds tissue fluids
Beneath the skin between muscles, beneath epithelial tissue
Loose connective tissue
Cell in fluid- gel matrix
Protects insulates and stores fat. At first these cells resembles fibroblast, but as the accumulate fat, they in large, and their nuclei are pushed to one side. Adipose cushions joints and some organs such as the kidneys.
Beneath the skin around the kidneys, between the eyeballs, on the surface of the heart.
Adipose tissue-
Cells in fluid gel matrix
Supports, provides internal frame work of certain organs
Walls of the liver, spleen, and lymphatic organs
Reticular connective tissue-
Dense connective tissue-
Cells in fluid gel matrix
Binds organs, body parts together
Tendons, ligaments, dermis the blood supply to regular dense connective tissue is poor, slowing tissue repair9a sprain around a joint takes a long time to heal)
Dense connective tissue-
Cells in fluid gel matrix
Provides elastic quality (yellow elastic fibers} in parallel strands or in branching networks.
Connecting parts of the spinal column in walls of arteries and airways (hollow internal organs including the larger arteries, some portions of the heart, and larger airways.
Elastic connective tissue-
Cells in solid gel-matrix look some what like white glass
Supports, protects provides flexible frame work supporting rings of the respiratory passages.
Ends of bones, nose, and ring in the walls of the respiratory passages
Hyaline cartilage-
Cells in solid gel-matrix
Supports, protects provides flexible frame work (MORE FLEXABLE than hyaline cartilage.)
Framework of external ear and part of the larynx
Elastic cartilage-
Cells in solid gel-matrix
Supports, protects, absorbs shock
Between bony parts of the spinal column, parts of the pelvic girdle, and knee
Cells in solid matrix
Supports protects provides framework
Bones of skeleton, middle ear
Cells and platelets in the fluid matrix
Red blood cells transport gases: defends against disease, clotting
Throughout the body within a closed system of blood vessels and chambers of heart.
