Fsn Test #2 (Cells And Systems Of The Body)

Front 1

tissues

Back 1

collections of cells adapted to perform a specific function

Front 2

organ

Back 2

a group of tissues designed to perform a specific function (example the heart which contains muscle tissue, nerve tissue, and so on)

Front 3

organ system

Back 3

a collection of organs that work together to perform an overall function

Front 4

organelles

Back 4

compartments, particles, or filaments that perform specialized functions within a cell

Front 5

enzyme

Back 5

a compound that speeds the rate of a chemical process but is not altered by that process (almost all are proteins)

Front 6

cytoplasm

Back 6

the fluid and organelles (except the nucleus) in a cell

Front 7

mitochondria

Back 7

the main sites of energy production in a cell. They contain the pathway for oxidizing fat for fuel, among other metabolic pathways

Front 8

cell nucleus

Back 8

an organelle bound by its own double membrane and containing chromosomes, the genetic information for cell protein synthesis and cell replication

Front 9

gene

Back 9

a specific segment on a chromosome, provide the blueprint for the production of cell proteins

Front 10

epithelial tissue

Back 10

tissue that lines the outside surfaces and external passages

Front 11

connective tissue

Back 11

tissue that holds structures together

Front 12

muscle tissue

Back 12

tissue that contracts to cause movement

Front 13

nervous tissue

Back 13

tissue that transports nerve impulses

Front 14

artery

Back 14

a blood vessel that carries blood away from the heart

Front 15

capillary

Back 15

exchange of nutrients and waste

Front 16

vein

Back 16

a blood vessel that carries blood to the heart

Front 17

urea

Back 17

nitrogenous waste product of protein metabolism; major source of nitrogen in the urine

Front 18

nervous system

Back 18

the body system consisting of the brain, spinal chord, nerves, and sensory receptors. This system detects sensations, directs movements, and controls physiological and intellectual functions

Front 19

neuron

Back 19

the structural and functional unit of the nervous system. consists of cell body, dendrites, and an axon

Front 20

Immune System

Back 20

the body system consisting of white blood cells, lymph glands and vessels, and various other body tissues. Provides defense against foreign invaders, primarily due to the action of various types of white blood cells

Front 21

White Blood Cells

Back 21

they phagocytize bacteria, fungi, and viruses, as well as detoxify harmful proteins

Front 22

Digestion

Back 22

process by which food is broken down into their component molecules, either mechanically or chemically

Front 23

Absorption

Back 23

process by which molecules of food cross from the intestine into the cells
