, definition of a tissue: Answer: Cells (and intercellular material) that work together to perform a
function
term used to mean the "study of tissues?" Answer: Histology
Four main types of tissues: Answer: connective, epithelial, muscle, nervous
Tight junction: Answer: (Fluid-sealed) keeps fluid from entering between cells
Desmosome Answer: (Spot welding) hold cells together
gap junctions Answer: (Communication) allows chemicals to move between cells
functions of epithelial tissue Answer: protection, absorption, secretion, permeability
Name two places where epithelial tissue is found: Answer: Kidney and lungs
characteristics of epithelial tissue Answer: tightly packed cells, avascular, basement membrane,
regeneration, nerve supply, free surface
Free surface: Answer: Epithelial tissues often cover or line organs
Basement membrane is made of: Answer: Collagen and glycoproteins and attached to
epithelium to connective tissues underneath
Epithelial tissues generally have cells that: Answer: Rapidly undergo mitosis. Example:
intestinal lining replaced every 2-3 days
How are epithelial tissues classified? Answer: shape and number of layers (simple, stratified,
squamous, cuboidal, columnar)
Simple squamous tissue epithelial tissue has how many layers of cells and what is their shape:
Answer: One layer of flat cells
simple squamous epithelium are located: Answer: lines the blood vessels and heart, air sacs of
lungs, body cavities and kidney tubules.
why are simple squamous epithelial tissue located there: Answer: A simple squamous layer of
cells provides a very thin layer of cells for diffusion across those cells
Two specific types of simple squamous epithelial tissue: Answer: Endothelium and
mesothelium
endothelium tissue lines Answer: The heart, blood and lymphatic vessel
Mesothelium (simple squamous) is Answer: a serous membrane of flat cells that lines the body
cavity and forms the squamous cells of the peritoneum, pericardium, and pleura.
Mesothelium function Answer: production of fluid to provide lubrication
The pleura is the membrane that surrounds the Answer: Lungs
