Homeostasis

Passive Transport system

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

1. Receptor

2. Control Center

3. Effector

Detection/Receptor

Specialized structures sense changes.

Integration/Control center

Brain interprets signals and decides changes.

Response/Effector

Organs/systems adjust conditions back to normal.
