CELL MOVEMENT Flashcards
Characterized by PSEUDOPODIUM
Amoeboid movt
Movement of an entire cell in relation to its surrounding (the whole cell moves)
Amoeboid movt
Attached to anything and bring the whole cell with it
Amoeboid movt
Example of amoebiid movt
WBC
From blood to tissue
Whip like movt of the CILIA on the surfaces of the cell
Ciliary movt
Ex of ciliary movt
Movt of cilia on respiratory passages
Movt in fallopian tube
Interstitial fluid
Extracellular fluid
Cell membrane is made up of
Lipids
Water loving
Head
Lipid soluble
Nonpolar
Tails
Lipid soluble matls
Vitamins
O2
Co2
Serves as channels
Lipids
Body weight is % fluid
56% fluid
2 types of fluid in the body
Intracellular
Extracellular
Inside the cell numerous in K, Mg P
Intracellular fluid
Diluted salt soln
Mostly Na and Cl
Extracellular fluid
Regulates the intracellular and extracellular fluid
Cell memb
2 mechanisms in movt across the cell membrane
Passive process
Active process
Move ions of molecules without energy expenditure
Passive process
Passive processes
DOF FBS
Diffusion
Osmosis
Filtration
Facilitated diffusion
Bulk flow
Solvent drag *downhill movt
Determines which molecules comes out and comes in
Permeability
Selectively permeable
Factors of solubility
SSS EC
Shape Size Solubility of mol Electric charge Combination of all factors varies from cell to cell
Differences between the concentrations of subs EXTRACELLULARLY and INTRACELLULARLY
Concentration gradient
Req energy source by the cell for movt across the cell memb
Transport subs AGAINST their concentration gradient
Active process
Uphill movement
Active process
2 types of active process
Carrier mediated active process
Transport mediated active process
You get substances inward
Endocytosis
2 types of endocytosis
Phagocytosis
Pinocytosis
Get subs outside the cell
Exocytosis
