    Study Notes

    Tissues

    • A tissue is a group of similar cells that perform a specific function.

    Organ and System

    • An organ is a structure composed of two or more types of tissues that work together to perform a specific function.
    • A system is a group of organs that work together to perform a specific function.

    Components of Tissue

    • The three components of tissue are cells, cell products, and matrix.

    Main Types of Tissue

    • The four main types of tissue are epithelial, connective, muscle, and nervous tissue.

    Epithelial Tissue

    • Epithelial tissue forms the lining of internal and external surfaces, such as skin, lung, and gut.
    • It provides a barrier against external environment, absorbs and secretes substances, and detects sensory stimuli.

    Endothelium

    • Endothelium is a type of epithelial tissue that lines blood vessels, lymph vessels, and serous cavities.

    Types of Epithelial Tissue

    • Simple epithelium is composed of a single layer of cells.
    • Stratified epithelium is composed of multiple layers of cells.
    • The main difference between simple and stratified epithelium is the number of cell layers.
    • The thickness of epithelium determines its function; for example, thick epithelium provides extra protection, while thin epithelium allows for easy diffusion.

    Shapes of Epithelial Cells

    • The three basic shapes of epithelial cells are cuboidal, squamous, and columnar.
    • Examples of each shape:
      • Cuboidal: kidney tubules
      • Squamous: skin
      • Columnar: intestine

    Types of Epithelial Cells

    • Simple cuboidal epithelium: forms the lining of kidney tubules and glands.
    • Simple squamous epithelium: forms the lining of skin, lung, and blood vessels.
    • Simple columnar epithelium: forms the lining of intestine and uterus.
    • Ciliated epithelium: has hair-like structures that move mucus and debris.
    • Stratified epithelium: forms the lining of skin, mouth, and vagina.
    • Transitional epithelium: forms the lining of bladder and ureters.

    Glands

    • Unicellular glands are single cells that produce and secrete substances, found in the lining of intestine and lung.
    • Exocrine glands produce and secrete substances into a duct, such as sweat glands.
    • Endocrine glands produce and secrete hormones directly into the bloodstream, such as thyroid gland.

    Connective Tissue

    • The function of connective tissue is to provide support, structure, and protection to the body.

    Tissues
