Homeostasis And AutoMatic Control System

Question 1

What is Homeostasis

Answer 1

• This is the regulation of the internal conditions of a cell or organism to maintain optimal conditions for function in response to internal or external changes.
• It is when the body keeps internal conditions as constant as possible.

Question 2

What are the three features of the automatic control system?

Answer 2

1. Receptor Cells
2. Co-ordination Centre
3. Effector

Question 3

What are the two automatic control systems in humans?

Answer 3

Nervous system and hormones

Question 4

What is the purpose of receptor cells?

Answer 4

• Detects changes in the environment.
• this is also known as detecting a stimulus.

Question 5

What is an example of internal change to the environment (homeostasis)?

Answer 5

Concentration of glucose in the blood.

Question 6

What is an example of external change to the environment (homeostasis)?

Answer 6

Temperature of the skin.

Question 7

What does the coordination centre do? (Homeostasis)

Answer 7

Receives and Processes information from the receptor cells.

Question 8

What are three coordination centres in the human body?

Answer 8

• Brain
• Spinal Chord
• Pancreas

Question 9

What is the purpose of effectors (Homeostasis)?

Answer 9

To carry out a response / restore optimal levels

Question 10

What are examples of effectors in the human body? (Homeostasis)

Answer 10

Glands and Muscles

Question 11

What is the order in which the automatic control system’s factors come?

Answer 11

Receptor Cell -> Coordination centre -> effector
