Write the word or phrase that best completes each statement or answers the question. 59) Areolar or loose connective 60) lacuna 61) branched 62) Skeletal 63) Chondrocytes 64) keratinized stratified squamous epithelium 65) simple cuboidal 66) basement membrane 67) phagocytosis 68) 1-4-3-7-6-5-2 69) Adipocytes contain a fat-filled vacuole that can fill or empty, causing the cell to gain or lose volume. 70) Tendons are composed of dense regular connective tissue, which consists of densely packed, parallel connective tissue fibers. This type of tissue has relatively few cells and vascular supply is poor; consequently, repair is slow. Because of the structure of the tissue, surgical repair can be compared to attempting to suture two bristle brushes together. 71) In epithelial tissue the cells are packed together very tightly. Epithelial tissue is avascular. Epithelial tissue has three cell types that cover or line things and make tubes. Epithelial tissue has no fibers and it tends to be polar. Connective tissue has cells spaced far apart and is highly vascular (except cartilage). The cells of connective tissue vary greatly in shape and size. Connective tissue glues other tissues together and has three fiber types. Connective tissue tends to be nonpolar. Connective tissue has a large amount of ground substance, epithelial tissue does not. 72) Blood does not give mechanical support, its matrix is fluid, the cells are loose, the fibers are soluble, it carries nutrients, waste products, and other substances and attaches to several gasses. ESSAY. Write your answer in the space provided or on a separate sheet of paper. 73) The sweeping action of the ciliated epithelium is essential in order to propel inhaled dust and other debris out of the respiratory tract. Anything that inhibits this mechanism would allow foreign substances to remain in the tract, which may cause damage. Chemicals such as nicotine may inhibit the action of the cilia, allowing carbon particles found in smoke to remain in the lungs. 74) Epithelium gives rise to most cancers. This is probably because epithelial cells divide more, leading to more opportunity for damage to growth control mechanisms, and because epithelia are more often in contact with environmental insults such as ultraviolet radiation and carcinogens. 2
Answer Key Testname: 4-TISSUES.TST 75) Macrophages are large, irregularly shaped cells that act as key defenders that avidly phagocytize a broad variety of foreign materials, ranging from foreign molecules to entire bacteria to dust particles. This "big eater" also disposes of dead tissue cells which helps to clean out the wound, allowing for granulation tissue to form. 76) The skin is the largest organ in the body and protects underlying tissues from injury by preventing the passage of microorganisms. The skin and the mucus membranes are considered the body's first line of defense. 77) Pain, swelling, redness, and heat. 3
