CAMPBELL BIOLOGY EXAM 2
CHAPTER 40 Q’S AND A’S
interstitial fluid - ANSWER-liquid found between the cells of the body that provides
much of the liquid environment of the body
circulatory fluid - ANSWER-blood or hemolymph
tissues - ANSWER-groups of similar cells that perform a specific function in an
organism
4 types of animal tissue - ANSWER-1. Epithelial tissue
2. Connective tissue
3. Nervous tissue
4. Muscle tissue
epithelia - ANSWER-Tissues that cover the internal and external surfaces of the
body, the cells of which are held together with specialized structures such as tight
junctions.
connective tissue - ANSWER-One of the four basic tissue types in the body
(epithelial, connective, muscle, and nervous). Connective tissue is a supportive
tissue consisting of a relatively few cells scattered among a great deal of
extracellular material (matrix), and includes adipose tissue (fat), bone, cartilage, the
dermis of teh skin, tendons, ligaments, and blood.
fibroblasts - ANSWER-connective tissue cells that produce fibrous components of
extracellular matrix like collagen and elastin
macrophages - ANSWER-Found within the lymph nodes, they are phagocytes that
destroy bacteria, cancer cells, and other foreign matter in the lymphatic stream.
collagenous fibers - ANSWER-Strong and flexible connective tissue fibers that
contain the protein collagen
Reticular fibers - ANSWER-join connective tissue to adjacent tissues
elastic fibers - ANSWER-Flexible and "stretchy" fibers that add elasticity to tissue
loose connective tissue - ANSWER-The most widespread connective tissue in the
vertebrate body. It binds epithelia to underlying tissues and functions as packing
material, holding organs in place.
