Tissues Flashcards
(26 cards)
Cells closely packed that cover exterior surfaces of the body, line internal cavities and the outside of organs and form certain glands
Epthelial Tissue
It provides the body’s FIRST line of pretection
Controls permeability of substances
Secretion of chemicals compounds onto their surfaces
Epithelial Tissue
Three types of epithelial tissue (check presentation for images)
Squamous, Cubodial and Columnar
Epithelial tissue located in the lungs’ air sacs, heart lining, vlood vessels and lymphatic vessels. It allows to pass through by diffusion and filtration and secretes lubricating substance CHECK IMAGE
Simple Squamous Epithelium
Epithelial tissue In ducts and secretory portions of small glands and in kidney tubules; It secretes and absorbs CHECK IMAGE
Simple Cubodial Epithelium
Epithelial tissue in bronchi, uterine tubes and uterus and digestive tract and bladder; absorbs, secretes mucous and enzymes CHECK IMAGE
Simple columnar Epithelium
Epithelial tissue in trachea and upper respiratory tract; secretes mucous and moves it CHECK IMAGE
Pseudostratified Columnar Epithelium
Epithelial tissue in the esophagus, mouth and vagina; protects against abrasion CHECK IMAGE
Stratified Squamous Epithelium
Epithelial Tissue on sweat glands, salivary glands and mammary glands; protective tissue
Stratified cubodial Epithelium
Combination of ________ tissue cells dispered in a matrix
Conncetive
Ground subtstance made of polysaccharids often crisscrossed by protein fibers such as collagen fiber, elastic fiber and reticular
Matrix
Make up of connective tissue
Cells + ground substance + protein fiber
It supports and connects other tissues; protects from microoorganisms and transport of fluid nutrients
Connective Tissue
3 categories of connective tissue:
connective, supportive and fluid
Dense types of _______ tissue include ligaments and tendons. Loose ones are adipose, areolar and reticular
CHECK IMAGE
Connective
Cartilage and bones are (CHECK IMAGE)
supportive
Blood (red blood cells) and lymph (white blood cell)
fluid connective
Allow movement; contractile, meaning they can shorten and generate a pulling force.
Muscle Tissue
3 types of muscle tissue
skeletal, smooth, cardiac
Long cylindrical fiber; stirated; peipherically located nuclei; volunatry movement, produces heat and protects organs; attatched to bones and around entrance points to body CHECK IMAGE
skeletal tissue (muscle tissue)
short, branched, striated, sigle central nucleus; contracts to pump blood in the heart CHECK IMAGE
Cardiac Tissue (muscle tissue)
short, spindle shaped, no sitartion, single nucleus per fiber; involuntary movement, moves food, involuntary respiration, moves secretions, regulates flow of blood in arteries by contraction; walls of major organs and passage ways CHECK IMAGE
Smooth Tissue (Muscle Tissue)
Characterized as being excitable and capable of sending and receiving electrochemical signals that provide the body the information in the form of nerve impulses that communicate between regions of the body
Nervous Tissue
Cells in nervous tissue
Neuron, neuroglia
