Front 1

Tissue

Back 1

an aggregation of cells performing a similar function

Front 2

Histology

Back 2

the study of microscopic structure of tissues

Front 3

4 Primary Tissue Types

Back 3

1. Epithelial

2. Connective

3. Muscular

4. Nervous

Front 4

Epithelial Tissue

Back 4

lines cavities (lumen), covers surfaces, forms glands, always has a free surface

Front 5

Connective Tissue

Back 5

Protects and connects other tissues, transport system, primary energy reserve

Front 6

Muscle Tissue

Back 6

responsible for movement, produces heat

Front 7

Nervous Tissue

Back 7

generates and detects action potentials (nerve impulses)

Front 8

Intracellular Fluid (ICF)

Back 8

Fluid within cells

Front 9

Extracellular Fluid (ECF)

Back 9

Fluid outside body cells

*consists of ISF and Plasma

Front 10

Interstitial Fluid (ISF)

Back 10

ECF that fills narrow spaces between cells of

tissues

Front 11

Plasma

Back 11

liquid portion of blood

Front 12

Fluid Mosaic Model

Back 12

continually moving sea of fluid lipids that contains a mosaic of many different proteins

Front 13

Plasma Membrane

Back 13

a flexible yet sturdy barrier that surrounds and contains the cytoplasm

Front 14

Phospholipid Bilayer

Back 14

two back to back layers made up of three types of lipid molecules: phospholipids, cholesterol, and glycolipids

Front 15

selective permeability

Back 15

permits some substance to pass more readily than others

Front 16

Active Process

Back 16

substance moving against its gradient

Front 17

Passive Process

Back 17

substance moving down its gradient

Front 18

Solute

Back 18

MINOR (dissolved in solvent)

ex: salt

Front 19

Solvent

Back 19

MAJOR (dissolves the solute)

ex: water

Front 20

Diffusion

Back 20

net movement of solutes from a region of greater concentration to a region of to a region of lesser concentration (moving down a concentration gradient - passive transport)

Front 21

Osmosis

Back 21

specialized form of diffusion, diffusion of solvent across a selectively permeable membrane in response to differences in solute concentrations, movement from high solvent concentration to low solvent concentration, passive process
