Campbell biology chapter 40 Exam Questions With All Correct Answers A+ Pass 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. Fibrous connective tissue - Answer- A dense tissue with large numbers of collagenous fibers organized into parallel bundles. This is the dominant tissue in tendons and ligaments. bone - Answer- rigid connective tissue that makes up the skeleton of vertebrates adipose tissue - Answer- a kind of body tissue containing stored fat that serves as a source of energy cartilage - Answer- strong connective tissue that supports the body and is softer and more flexible than bone Muscle tissue - Answer- Tissue consisting of long muscle cells that are capable of contracting when stimulated by nerve impulses. Three types skeletal, cardiac, and smooth. nervous tissue - Answer- A body tissue that carries electrical messages back and forth between the brain and every other part of the body. neurons - Answer- Individual cells in the nervous system that receive, integrate, and transmit information. Glia - Answer- cells that support, nurture, and insulate neurons, remove debris when neurons die, enhance the formation and maintenance of neural connections, and modify neuronal functioning Hormones - Answer- chemical messengers, mostly those manufactured by the endocrine glands, that are produced in one tissue and affect another regulator - Answer- an animal for which mechanisms of homeostasis moderate internal changes in the face of external fluctuations conformer - Answer- organisms that do not regulate their internal conditions; they change as their external environment changes homeostasis - Answer- metabolic equilibrium actively maintained by several complex biological mechanisms that operate via the autonomic nervous system to offset disrupting changes set point - Answer- tells what a particular value should be negative feedback - Answer- a mechanism of response in which a stimulus initiates reactions that reduce the stimulus positive feedback - Answer- A physiological control mechanism in which a change in some variable triggers mechanisms that amplify the change.
