Endocrine System: How Hormones Work?

How does the endocrine system work? In this video, we explain how hormones function in simple words — from the megacity analogy (the nervous system is telephone wires, the endocrine system is a courier service) to how insulin regulates blood sugar step by step, the difference between endocrine and exocrine glands, negative vs positive feedback loops, and what happens when hormone levels go wrong (hyperthyroidism, Type 1 diabetes). Whether you're a biology student, curious about how your body keeps itself balanced, or want to understand the difference between the nervous system and the endocrine system, this beginner-friendly animated explainer covers it all.
