Homeostasis

What is homeostasis?

• A process of maintaining a stable internal environment

• A process of maintaining a stable external environment

• A process of increasing body temperature

• A process of decreasing body temperature

What are the main components of automatic control systems?

• Sensors, Coordination centers, Executors

• Sensors, Coordinators, Executors

• Receptors, Coordination centers, Effectors

• Receptors, Coordinators, Effectors

How does the nervous system communicate within the body?

• Through gland secretions

• Through hormones released into the bloodstream

• Through electrical impulses through nerves

• Through muscle contractions

What is the function of effectors in automatic control systems?

• Send signals to the brain

• Carry out the necessary changes

• Interpret changes in the body

• Detect changes in the environment

What is the mechanism called that maintains stable internal conditions?

• Negative feedback

• Feedback loop

• Positive feedback

• Neutral feedback

How does negative feedback work in maintaining homeostasis?

• It increases the levels of substances

• It fluctuates the levels of substances

• It decreases the levels of substances

• It has no effect on substance levels

What is the role of the endocrine system in homeostasis?

• Detects changes in the environment

• Relies on hormones released into the bloodstream

• Sends electrical impulses through nerves

• Interprets changes in the body

What happens if the glucose level in the blood gets too high?

• Negative feedback decreases it

• It remains high

• It decreases

• Positive feedback increases it

How does the body respond to a low room temperature?

• By decreasing body temperature

• By increasing body temperature

• By shivering

• By sweating

What is the overall process of maintaining a stable internal environment called?

• Nervous system

• Feedback loop

• Homeostasis

• Endocrine system
