Tissues Flashcards
Inside and out side surfaces
Main glandular tissue’s secretion
Cells laid out in sheets with strong connections/attachments
Cells packed tightly together
Epithelial tissues
Attached to underlying connective tissue by no cellular, nonliving (fibers and glue) basement membrane.
Epithelial tissue
The tissue that performs the epithelial organ’s function
Parenchyma ( the actual cells)
The tissue that supports the organ’s function
Stroma ( connective tissue)
Outside the cell network; typically exposed to world around it
Lumen
thin, fibrous, extracellular matric tissue that seperates the lining of an internal or external body surface from underlying connective tissue
Basement membrane
Six specific types of epithelial tissues categorized based on their ———– and ————-.
shape and layering
we wont distinguish glandular epithelium because —–
it is the stratified cuboidal or columnar type.
——— single layer (simple) of thin, flattened cells (squamous)
Function is ——-
Found in ——-
Simple squamous,
Diffusion and filtration
Air sacs of the lungs, walls of capillaries (very thin blood lining at the cell level)
Single layer, cube-shaped cells
Function is ——–
Found in
Simple cuboidal
secretion and absorption
lining of kidney tubulues, ducts/glands, covering surface of ovaries.
——–single layer, elongated cells with their nuclei in the same position ( usually near the basement membrane)
Function is ——
Found in the ——
Columnar
Secretion and absorption
lining of digestive tract and uterus
contains scatter ———– functioning in the secretion of mucus
Goblet cells
tiny finger like processes from their free surface- increase surface for absorption
Microvilli
help movement of particles
Cilia
multilayered squamous cells
Function is——
Found in —–
stratified squamous
protection
Lining body cavities like skin, mouth, anus and vagina
Appear “ stratifies” but really a single layer with uneven nuclei giving the appearance of layered cells- uneven assortment of nuclei
pseudostratified
tiny, hair like projections for sweeping materials along a surface
Function is —–
ciliated
secretion, ciliated movement
pseudostratified columnar epithelial cells contains ———
location is —-
goblet cells,
lining of the air passages and tubes of the respiratory tract,, also in reproductive track
thick, layered cuboidal cells———
Function is ——–
Found in ——
Transitional Epithelium
Contract and stretch to form a barrier to block diffusion ( no leaking) and block infection.
Lining of bladder and genital tract, urinary system
Most abundant tissue in the body, found throughout every system, sticks and shiny, glide over tissues prevents friction;
Examples:
Connective Tissue (stroma)
cartilage, bursae, synovial fluid
Explain the functions of connective tissue
Connects structures, provides support, protection, framework, fills space, stores fat, produces blood cells, fights infection, helps repair tissues
1) connective tissue composed of ——
2) made up of ——–
3) most has a ——-with reproduce over —–
1) more scattered cells with abundant intracellular and extra cellular (matrix).
2) a ground substance ( fluid, semi-solid) and fibers.
3) blood supply, various time frames ( quick to basically never)
