Study Set Content:
lungs type of tissue that allows gas exchange
simple squamous epithelium
lungs type of tissue that allows gas exchange
simple squamous epithelium
- Types of tissue in the kidneys helps filter wastes from the blood while keeping blood cells inside the blood vessels.
simple squamous epithelium
Single layer of flat, often hexagonal cells; the nuclei appear as bumps when viewed in cross section because the cells are so flat
simple squamous epithelium
Function of simple squamous epithelium
Diffusion, filtration, some secretion, and some protection against friction
Location of simple squamous epithelium
Lining of blood vessels and the heart, lymphatic vessels, alveoli of the lungs, portions of the kidney tubules, lining of serious membranes of body cavities (pleural, pericardial, peritoneal)
is a single layer of cube-like cells that carry out active transport, facilitated diffusion, or secretion.
Simple cuboidal epithelium
Single layer of cube-shaped cells; some cells have microvilli (kidney tubules) or cilia (terminal bronchioles of the lungs)
Simple cuboidal epithelium
Simple cuboidal epithelium function
Secretion and absorption by cells of the kidney tubules; secretion by cells of glands and choroid plexuses; movement of particles embedded in mucus out of terminal bronchioles by ciliated cells
Simple Cuboidal Epithelium location
Kidney tubules, glands and their ducts, choroid plexuses of the brain, lining of terminal bronchioles of the lungs, and surfaces of the ovaries
- is a single layer of tall, thin cells.
Simple columnar epithelium
The large size of these cells enables them to perform complex function, such as
secretion
- type of cell small intestine produces and secretes mucus and digestive enzymes.
simple Columnar epithelium
Single layer of tall, narrow cells; some cells have cilia (bronchioles of lungs, auditory tubes, uterine tubes, and uterus) or microvilli (intestines)
Simple Columnar Epithelium
Function of simple columnar epithelium
Movement of particles out of the bronchioles of the lungs by ciliated cells; partially responsible for the movement of oocytes through the uterine tubes by ciliated cells; secretion by cells of the glands, the stomach, and the intestines; absorption by cells of the intestines
Location of simple columnar epithelium
Glands and some ducts, bronchioles of lungs, auditory tubes, uterus, uterine tubes, stomach, intestines, gallbladder, bile ducts, and ventricles of the brain
secretes mucus; which covers its free surface
Pseudostratified columnar epithelium
- in the airways move the mucus and accumulated debris toward the throat, where it is swallowed.
Cilia
Single layer of the cells; some cells are tall and thin and reach the free surface, and others do not; the nuclei of these cells are at different levels and appear stratified; the cells are almost always ciliated and are associated with goblet cells that secrete mucus onto free surface
Pseudostratified Columnar Epithelium
Location Pseudostratified Columnar Epithelium
Lining of nasal cavity, nasal sinuses, auditory tubes, pharynx, trachea, and bronchi of lungs
