Human Anatomy and Physiology Tissues questions and answers 100% guaranteed success. epithelial tissue - correct e: cells are avascular (closely packed together, little or no intercellular material between adjacent cells); major roles include secretion, absorption, protection, and synthesizing hormones; covers external body surfaces and lines inner walls of cavities and organs; has basement membrane (attachment) and free surface (exposed side); classified by shape and layer squamous - correct elium: flat cuboidal - correct elium: cube-shaped columnar - correct elium: greater in height than width simple - correct elium: single layer stratified - correct elium: multiple layers simple squamous - correct elium: singer layer of flat cells; lines inside wall of blood vessels, forms walls of capillaries and lung air sacs - absorption by diffusion, filtration, osmosis; secretion simple cuboidal - correct elium: single layer of cube-shaped cells; forms walls of ducts in skin glands and kidney tubules - secretion, absorption simple columnar - correct elium: single layer of column-shaped cells; lines inside walls of stomach and intestines - protection, secretion, absorption, moving of mucus w/ cilia stratified squamous - correct elium: multiple layers of cells, with cells along free edge flattened in shape; superficial layer of the skin, mouth, and throat (friction) - protection pseudostratified columnar - correct elium: single layer of irregularly shaped cells that appear multi-layered, often with cilia; lines inside walls of larynx, trachea, and bronchi - protection transitional - correct elium: multiple layers of spherical or irregularly shaped cells; lines inside walls of urinary bladder and ureter - permits stretching glandular - correct elium: specialized epithelium that manufacture and secrete products exocrine glands - correct s that empty products into ducts. the ducts transport products to the body surface or into a cavity. (salivary glands, oil glands in skin, sweat glands) endocrine glands - correct s that secrete products into the extracellular space, where the products diffuse into the bloodstream. (pituitary gland, thyroid gland, adrenal glands) connective tissue - correct e: cells are vascular (widely scattered with large amounts of nonliving intercellular material); contains ground substance (protein-sugar molecules and protein fibers); functions include supporting body structures and gluing tissues and organs in place; contains two types of cells: one maintains intercellular material and one protects tissue from infections; has great capacity for growth and repair collagenous fibers - correct of protein fiber in connective tissue; thick, wavelike strands; resists stretching; has great tensile strength; composed of most abundant protein in the body (found in tendons, scar tissue) elastic fibers - correct of protein fiber in connective tissue; elasticity (ability to stretch) and extensibility (ability to return to original shape); found in skin reticular fibers - correct of protein fiber in connective tissue; resists physical stress; least abundant of all the fibers areolar tissue - correct connective tissue; most common connective tissue; all 3 protein fibers present in a fluid ground substance; has fibroblasts (cells that produce fibers and ground substance) and macrophages (white blood cells); functions include being a structural anchor to body parts; found between skin and muscles, surface of organs, filling spaces between organs adipose tissue - correct connective tissue; has adipocytes (specialized fibroblasts that contain large deposits of fat); has minimal intercellular material; functions include storing energy as fat, being an insulating pad between organs, being a shock absorber reticular tissue - correct connective tissue; contains reticular fibers; makes a 3D network for support in the liver and spleen dense connective tissue - correct ctive tissue: protein fibers are packed closely together with little ground substance dense irregular connective tissue - correct ctive tissue: fibers extend in various directions; found in skin and round bone and cartilage dense regular connective tissue - correct ctive tissue: fibers extend parallel to each other; found in tendons and ligaments cartilage - correct ctive tissue: more solid than connective tissue proper; has a matrix of protein fibers and thickened ground substance; has chondrocytes (cartilage cells that maintain the matrix, embedded in small chambers called lacunae); has perichondium (dense connective tissue that surrounds the cartilage and is vascular; materials diffuse from perichondrium to chondrocytes); 3 types hyaline cartilage - correct ctive tissue: most abundant type of cartilage; matrix is dominated by chondroitin sulfate and collagen; sparsely distributed chondrocytes in matrix; found in the upper portion of the respiratory tract (trachea and bronci), ends of bones and ribs, skeleton of a fetus elastic cartilage - correct ctive tissue: elastic fibers dominate the matrix and weave through the chondrocytes; found in ears, end of nose, epiglottis
