A&p Cell Phisiology

Front 1

Interstitial fluid or extracellular fluid

Back 1

Baths the exterior of the cell, rich in nutrients

Front 2

Intracellular fluid

Back 2

the nucleoplasm and cytosol
inside the plasma membrane

Front 3

Passive transport

Back 3

substances are transported across the membrane without energy input from the cell

Front 4

Active transport

Back 4

the cell provides metabolic energy ATP that drives the transport process

Front 5

Osmosis

Back 5

the diffusion of a solution through a membrane from a dilute solution into a more concentrated one

Front 6

Kenetic Energy

Back 6

(energy of motion)bouncing molecules move away from a region of more concentration to one of less concentration

Front 7

Concentration Gradient

Back 7

Moveing from area of more concentration to an area of less concentration

Front 8

Simple Diffusion

Back 8

the unassisted diffusion of solutes through the plasma membrane (or any selectivly permeable membrane)

Front 9

Facillitated Diffusion

Back 9

Provides passage for certian needed substances (glucose) that are lipid insoluableand to large to pass thru the membrane pores a protien membrane channel is used

Front 10

Osmotic Pressure

Back 10

the tendancy of a solution to hold water or pull into it,directly related to the concentration of solutesin the solution

Front 11

Tonicity

Back 11

the ability of a solution to change yhe size and shape of cells by altering the amount of water they contain

Front 12

Isotonic Solutions

Back 12

Have the same solute and water concentration that a cell has,(Lactated Ringer, 5% dextrose, 0.9% saline)

Front 13

Hypertonic Solution

Back 13

solution contains more solutes than are inside the cell, causes the cell to shrink or crenate, givrn to patients who have edema

Front 14

Hypotonic Solution

Back 14

the solution contains less solutes and more water than the cell, causing cells to plump up rapidly as water rushes into them. may cause cell to burst

Front 15

Solute Pumping

Back 15

Active transport reqires ATP to energize its protien carriers to move against concentration gradient (sodium-potasssium pump)
