Your body has an amazing chemical messaging system called hormones... Show more





Think of your body as having its own master controller - that's the pituitary gland sitting right next to your brain. This tiny but mighty gland either sends out hormones to control your body directly or tells other glands what to do, making it the boss of your entire hormone system.
Your thyroid gland in your neck produces thyroxine, which is like your body's speed controller. This hormone manages your metabolism (how fast you burn energy), plus it's crucial for your growth and development - pretty important stuff when you're still growing!
When you need a sudden burst of energy or feel scared, thank your adrenal glands sitting on top of your kidneys. They pump out adrenaline to trigger your 'fight or flight' response, making your heart race and boosting blood flow to help you react quickly.
Remember: Each gland has a specific location and job - the pituitary controls others, the thyroid manages metabolism, and the adrenals handle emergency responses.

Your pancreas is like a sugar referee, releasing two opposing hormones called insulin and glucagon. These work together to keep your blood glucose levels perfectly balanced, making sure your cells get the energy they need without having too much or too little sugar floating around.
During puberty, different hormones kick into high gear depending on whether you're male or female. Testicles produce testosterone, which causes all those male puberty changes like facial hair growth, voice deepening, and sperm production.
For females, the ovaries release oestrogen and progesterone. Oestrogen helps produce eggs and thickens the uterus lining each month, while progesterone maintains that lining during ovulation - essentially preparing the body for potential pregnancy.
Key Point: Pancreatic hormones control blood sugar, whilst sex hormones (testosterone, oestrogen, progesterone) drive all the physical changes during puberty.

This app has made me feel so much more confident in my exam prep, not only through boosting my own self confidence through the features that allow you to connect with others and feel less alone, but also through the way the app itself is centred around making you feel better. It is easy to navigate, fun to use, and helpful to anyone struggling in absolutely any way.

I know a lot of apps use fake accounts to boost their reviews but this app deserves it all. Originally I was getting 4 in my English exams and this time I got a grade 7. I didn’t even know about this app three days until the exam and it has helped A LOT. Please actually trust me and use it as I’m sure you too will see developments.
