| Question | Answer |
|---|---|
| Fibroblasts | cells that connect body parts |
| Epithielial cell | cells that cover and line body organs |
| Skeletal muscle and smooth muscle | cells that move organs and body parts |
| Fat cell | cell that store nutrients |
| Macrophage (a phgocyte cell) | cells that fight disease |
| Nerve cells | cells that gather information and control body function |
| Oocyte (female) Sperm (male) | cels of reproduction |
| Interstitial fluid | fluid that continuously baths the exterior of the cell |
| Intracellular fluid | inside the cell (cytoplasm and cytosol) |
| Selective permiability | a barrier allows some substances to pass thru while excluding others |
| Passive transport processes | substances are transported across the membrane without energy input from the cell |
| active transport processes | the cell provides metabolic energy (ATP) that drives the transport system |
| Kinetic energy | all molecules possess_________ __________(energy in motion) |
| concentration gradient | molecule move awy from a region where they are mopre concentrated to an region of less concentration |
| Simple diffusion | particles in solution move continuously and collide constantly with other particles, as a result particles tend to move away from more concentrated areas to evenly distribute particle in solution |
| Facilitated diffusion | to move along concentration gradient certian molecule need a protein channel or protein molecule that acts as a transport vehicle |
| Osmosis | diffusion of eater through a selectively permiable membrane such a the plasma membrane is specifically called_______ |
| Osmotic pressure | the tendancy of a solution to hold or "pull" water into it is called_________ _______ |
| Isotonic solution | have the same solute and water concentration as the cell |
| Hypertonic solution | contains more solutes than the inside of the cell |
| Crenate | Shrinking of the blood cell is called ______ |
| Hypotonic solution | when a solution contains fewer solutes than the cell does |
| Red Blood cells exposed to isotonic solution | no change to the cell (ringers lactate, normal saline) |
| Red Blood cells exposed to hypertonic solution | creanate or shrinking takes place |
| Red Blood cells exposed to hypotonic solutions | causes the cell to plump up as water enters the cell along concentration gradient, (distilled water most extreme form) |
| Solute pumping | uses ATP to energize it protein carriers (more simply called active transport) |
| Phagocytosis | term that means cell eating act as scavengers cells that police and protect the body by ingesting bacteria and other forien debris as well as dead body cells (whit blood cells) |
| Pinocytosis | if cells can eat tehy can also drink this is called _________ |
| Exocytosis | the means by which cells actively secrete hormones, mucus, and other cell products or eject cellular waste (out of the cell) |
| Endocytosis | includes those ATP-requireing processes that take up ,or engulf, extracellular substances (into the cell) |
