Movement of substances from high to low concentration without energy.
Diffusion
Movement of substances from high to low concentration.
Facilitated Diffusion
Movement of substances with the help of carrier proteins.
Osmosis
Movement of water from high to low concentration.
Active transport
Movement from low to high concentration using energy.
Osmotic Pressure
Minimum pressure to prevent liquid inflow.
Hydrostatic Pressure
Pressure from liquid due to gravity.
Osmolality
Concentration expressed as solute particles per kg.
Carrier Mediated Transport
Molecules transported using carrier proteins.
Homeostasis
Self-regulating process in which biological systems maintain stability while adjusting to changing external conditions
Steps in homeostasis
Receptor
Control Center
Effector
Detection/Receptor
Specialized structures sense changes.
Integration/Control center
