ICSE Class 7 Biology Epithelial tissue
|
Epithelial tissue is widespread throughout the body.
Think about it!
Think about it!
Cuboidal epithelium is a type of epithelium that consists of a single layer of cuboidal (cube-like) cells. These cuboidal cells have large, spherical, and central nuclei. Ciliated epithelium performs the function of moving particles or fluid over the epithelial surface in such structures as the trachea, bronchial tubes, and nasal cavities Columnar epithelia are tissues made of a single layer of long epithelial cells that are often seen in regions where absorption and secretion are important features. The cells of this epithelium are arranged in a neat row with the nuclei at the same level, near the basal end. Squamous epithelium is a single layer of flat cells in contact with the basal lamina (one of the two layers of the basement membrane) of the epithelium. This type of epithelium is often permeable and occurs where small molecules need to pass quickly through the membranes via filtration or diffusion.
Goblet cells are simple columnar goblet shaped like epithelial cells that secrete gel-forming mucins, like mucin
The large air passages that lead from the trachea (windpipe) to the lungs.
Epithelial tissue is a sheet of cells that covers the body's surface.
