The Endocrine System 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 the endocrine system and what does it do?

The endocrine system is made up of glands that secrete hormones into the bloodstream. These hormones act on target organs to produce effects, and their effects are slower but longer-lasting compared to the nervous system.

Which hormones are produced by the pituitary gland?

The pituitary gland produces many hormones, including anti-diuretic hormone (ADH), follicle-stimulating hormone (FSH), and luteinising hormone (LH).

What hormones are produced by the pancreas and what do they regulate?

The pancreas produces insulin and glucagon, which regulate blood sugar levels.

Why is the pituitary gland often referred to as the ‘master gland’?

The pituitary gland is called the ‘master gland’ because it secretes hormones that act on other glands, causing them to release hormones and trigger various effects in the body.

What hormones are produced by the adrenal glands and what are their effects?

The adrenal glands produce adrenaline, which prepares the body for ‘fight or flight’ responses by increasing heart rate, blood flow to muscles, and releasing stored energy.

What are the primary hormones produced by the ovaries and testes, and what do they regulate?

The ovaries produce oestrogen and progesterone, which regulate female reproductive functions.

The testes produce testosterone, which regulates male reproductive functions and secondary sexual characteristics.
