What Are Glands?
Glands are special organs in your body that make and release substances to help you stay alive and healthy. Some glands release hormones (chemical messengers), while others release things like sweat, saliva, or digestive juices.
Think of glands as tiny factories that work behind the scenes, keeping your body balanced and running smoothly.
Types of Glands
1. Endocrine Glands (Inside the Body)
- These release hormones directly into the bloodstream.
- Examples:
- Thyroid gland → controls metabolism and energy
- Adrenal glands → help manage stress with cortisol and adrenaline
- Pancreas (endocrine part) → makes insulin to control blood sugar
2. Exocrine Glands (Outside the Body)
- These release substances through ducts to specific parts of the body.
- Examples:
- Sweat glands → help cool you down
- Salivary glands → make saliva to start digestion
- Pancreas (exocrine part) → makes digestive juices for breaking down food
Why Are Glands Important?
- ⚡ Energy & Metabolism → Hormones from glands regulate how your body uses food for fuel.
- ❤️ Growth & Development → Glands control puberty, growth, and reproduction.
- 🛡️ Defense → Some glands (like lymph nodes) help fight infection.
- 🌡️ Balance → Keep your body’s systems in harmony (temperature, blood sugar, hydration).
Health Problems with Glands
When glands don’t work properly, problems can happen:
- Diabetes → pancreas not making enough insulin
- Hypothyroidism → thyroid too slow
- Hyperthyroidism → thyroid too fast
- Adrenal fatigue → stress hormones out of balance
Fun Fact 🌟
