Front

What detects that the system is outside of homeostasis and adjustments need to be made?

Back

Control center: The part of the body that receives information about the internal environment and initiates responses to restore balance.

Front

What is the 'post office' of the cell that packages proteins and fats?

Back

Golgi Apparatus: An organelle that modifies, sorts, and packages proteins and lipids for secretion or delivery to other organelles.

What are the 'garbage collectors' of the cell that remove waste?

Back

If the environment gets cold, we will often shiver in order to:

Back

Increase body temperature: Shivering generates heat through muscle activity to maintain body temperature.

Front

What is homeostasis?

Back

Homeostasis: The process by which living organisms regulate their internal environment to maintain stable, constant conditions.

Front

What role do effectors play in homeostasis?

Back

Effectors: Organs or cells that act to bring about a response to restore balance in the body.

Front

What is a stimulus in the context of homeostasis?

Back

Stimulus: A change in the environment that triggers a response in the body to maintain homeostasis.

Front

What is the function of the cell membrane?

Back

Cell Membrane: A protective barrier that regulates what enters and leaves the cell, maintaining homeostasis.

Front

What is the function of ribosomes?

Back

Ribosomes: Organelles that synthesize proteins by translating messenger RNA.
