Tissues

A & P I

Simple Squamous Epithelium

Single layer of flat cells, lines surfaces, facilitates diffusion and filtration. Found in the alveoli of the lungs and the lining of blood vessels

Simple Cuboidal Epithelium

A single layer of cube-shaped cells that function in secretion and absorption, commonly found in kidney tubules and glands

Simple Columnar Epithelium

A single layer of tall, column-shaped cells involved in absorption and secretion, often found in the lining of the digestive tract and uterus (if ciliated).

Stratified Columnar Epithelium

A type of epithelial tissue composed of multiple layers of cells, with the surface layer being columnar. Found in certain ducts and the male urethra

Pseudostratified columnar epithelium with cilia and goblet cells

A type of epithelial tissue that appears to have multiple layers due to varying cell heights but is actually a single layer. Found lining the respiratory tract

Stratified squamous non-kertatinizing epithelium

A type of epithelial tissue consisting of several layers of cells, where the outer layer is made up of flat, scale-like cells. It is found in moist areas such as the mouth, esophagus, and female canal

Stratified Squamous Keratinizing Epithelium

Tough multilayered tissue whose surface cells are dead and filled with waterproof protein keratin. Forms the skin

Transitional epithelium

Changes shape to allow organs to stretch and relax. Found in the urinary tract

Areolar Connective Tissue

Soft, flexible, and widely distributed loose connective tissue. Cushions and binds organs providing a fluid filled matrix

Adipose Tissue

Connective tissue made of fat cells. Holds lipids and triglycerides to release when the body needs fuel, physical cushion and thermal insulator

Reticular Connective Tissue

Specialized type of loose connective tissue characterized by thin branching fibers. Forms internal supporting framework of lymph nodes, spleen, tonsils. Supports developing blood cells in red bone marrow.

Dense Regular Connective Tissue

Fibrous connective tissue with densely packed collagen fibers arranged in parallel bundles. Found in tendons and ligaments.

Dense Irregular Connective Tissue

Thick interwoven collagen fibers provide strength. Found in deep layer of dermis, digestive tract

Elastic Connective Tissue

Dense tissue packed with branching elastin fibers allowing organs to stretch and return to original shape. Found in arteries and alveoli

Hyaline Cartilage

Most common glass like connective tissue. Found in ribs and nose

Elastic Cartilage

Highly flexible, bends easy and returns to original shape. Found in external ear, epiglottis

Fibrocartilage

Strongest cartilege, found in intervertebral discs

Spongy Bone

Interior layer of bone tissue found inside long bones, holds red bone marrow

Compact Bone

Hard dense outer layer of bone tissue, structural support, holds yellow bone marrow

Blood

Fluid connective tissue that circulates through heart, arteries, veins, and capillaries
