Tissue Types in Human Anatomy

A single layer of thin, flat cells allowing rapid diffusion and filtration; found in air sacs of lungs.

A single layer of cube-shaped cells with a centrally located nucleus; often found in glands and kidney tubules.

Multiple layers of flat cells; provides protection; found in areas like the mouth and vagina.

Multiple layers of cube-shaped cells; mainly found in secretory ducts of glands.

Tall, column-shaped cells; can be simple (one layer) or stratified (multiple layers); often in digestive tract.

Epithelium that can change shape; found in the bladder; allows stretching.

Single layer of cells that appear stratified; typically contains cilia and goblet cells; lines respiratory tract.

Main functions include absorption and secretion.

Found in kidney tubules, thyroid gland follicles, surface of ovary, and in secretory regions and ducts of most glands.

A single layer of taller cells with oval-shaped nuclei, often contains microvilli and goblet cells for secretion.

Primary roles include absorption and secretion of mucin.

Lines most of the digestive tract including the stomach, small intestine, and large intestine.

Specialized cells within columnar epithelium that secrete mucin.

Small finger-like projections on the apical surface of some epithelial cells, increasing surface area for absorption.

Thin, fibrous layer that separates epithelial tissue from connective tissue, providing support.

Cartilaginous structures between vertebrae with collagen fibers.

Type of cartilage with parallel collagen fibers for strength and shock absorption.

Flexible cartilage with abundant elastic fibers allowing shape maintenance.

Bone cells residing in lacunae within calcified matrix.

Bone tissue organized in a meshwork, contains hemopoietic tissue.

The most diverse and abundant tissue type, originating from mesoderm in embryos.

A mixture of protein fibers and ground substance filling spaces between cells in connective tissue.

Components of the extracellular matrix, including elastic fibers, collagen, and reticular fibers.

A mixture of proteins and carbohydrates with varying salts and water in the extracellular matrix.

Includes physical protection, support, binding, storage, transport, and immune protection.

Stem cells that can differentiate into various types of connective tissues.

A type of connective tissue that includes blood and lymph.

Includes cartilage and bone, providing structure and support.

Includes loose connective tissue and dense connective tissue, providing varying degrees of support and flexibility.

Cells found in cartilage and bone, respectively, located in small spaces called lacunae.

The liquid portion of blood that contains water, proteins, and dissolved substances.

Red blood cells that carry oxygen from the lungs to the body and carbon dioxide back to the lungs.

White blood cells responsible for protecting the body against infections and foreign invaders.

Cell fragments in blood that are crucial for blood clotting.

Transports oxygen, carbon dioxide, hormones, nutrients, and waste; protects body from infection; regulates temperature.

Found within blood vessels; white blood cells can move into surrounding tissues.

A type of connective tissue with a glassy matrix and irregular chondrocytes; provides support.

Provides support and flexibility; forms much of the fetal skeleton.

Found in the tip of the nose, trachea, larynx, and the ends of long bones.
