Endocrine System: Homeostasis And Negetive Feedback

Question 1

Tissue fluid

Answer 1

Fluid that surrounds all body cells

Question 2

Control centre

Answer 2

That processes the information and activates corrective mechanisms that it send to the effector

Question 3

Homeostasis

Answer 3

The process of maintaining the internal environment in a constant optimal state, despite constant changes in the external environment.

Question 4

Receptor

Answer 4

Detects a change from the set point and sends information to the control centre, usually the brain.

Answer 5

Control mechanisms whereby a change from the set point of any factor is corrected by bringing about a change in the
opposite ( negative)
direction
