Homeostasis Flashcards

1️⃣ Familiarise yourself with the flashcards:

  • Look through all the flashcards to see what’s on both sides.
  • Make sure you understand the information on each card. If something’s unclear, click the link to the revision notes at the bottom of the page for more details.

2️⃣ Test yourself:

  • Look at the question or prompt on each card and try to remember the answer before flipping it over.
  • Check the answer and make a note of any cards you find challenging and need to go over more.

3️⃣ Consistently Review and Practice:

  • Use spaced repetition: spend more time on the cards you struggle with and go over them more often.
  • Regularly review all the flashcards to help you better understand and retain the information over time.

Note: We may include questions that have multiple correct answers. It’s useful to remember specific examples to understand these concepts better.

What is homeostasis?

Homeostasis is the maintenance of a constant internal environment in the body, ensuring optimal conditions for enzymes and cell functions.

Name three things that homeostasis helps to control in the body.

Body temperature, water content, and blood glucose concentration.

What are the components of the body’s automatic control systems in homeostasis?

Receptors (detect stimuli), coordination centres (process information), and effectors (produce responses).

What mechanism does the body use to maintain internal conditions?

Negative feedback, which restores equilibrium when levels are too high or too low.

Describe the role of negative feedback when levels in the body are too high.

The receptor detects high levels, the coordination centre processes the information, and the effector produces a response to decrease the levels.

What happens when blood glucose levels are too low in the body?

The receptor detects low levels, the coordination centre processes the information, and the effector produces a response to increase the levels.
