How does sweating help regulate body temperature?

• By evaporating and drawing heat away

• By increasing blood flow

• By contracting muscles

• By increasing oxygen intake

What is the first step in the homeostasis process?

• Control center decision

• Effector response

• Receptor detection

• Signal transmission

What is the role of the control center in homeostasis?

• Producing sweat

• Generating heat

• Sending signals to effectors

• Detecting changes in the environment

What can cause a failure in homeostasis?

• Balanced internal conditions

• Proper functioning of effectors

• Stable external environment

• Interference with normal processes
