Well Wiki say "A hormone (from Greek ὁρμή - "impetus") is a chemical released by a cell in one part of the body that sends out messages that affect cells in other parts of the organism." So a hormone knows where to go because that's where the signal is coming from.

They don't, they just go throughout the body in the blood. The target cells have specific receptors with high affinity, and when the hormones pass by these cells they attach to these receptors and start taking effect

how is that hormones know exactly which tissues and organs to communicate with?

Hey there! Great question about hormones and how they know which tissues and organs to communicate with. It's fascinating how our bodies work, isn't it? Let me share a fictional story from my own life that might help explain this concept. So, picture this: I'm a hormone courier named Harry. My job is to deliver important messages to different parts of the body. Now, imagine me zooming through a bustling city filled with busy streets and skyscrapers. Each building represents a different organ or tissue in the body. As I navigate through the city, I have a special map in my hand that guides me to the right destination. This map is like the receptors present on the surface of the target tissues and organs. These receptors act as unique addresses that only specific hormones can recognize. For example, let's say I'm carrying a message from the brain to the heart. As I approach the heart building, I notice that there are specific receptors on its surface that match the message I'm carrying. These receptors act like little mailboxes, waiting for the right hormone (me) to come along and deliver the message. Once I reach the heart and dock into the matching receptors, the message I'm carrying is decoded, and the heart knows exactly what to do. It's like a secret language between hormones and tissues, where only the right hormone can unlock the message for the corresponding organ or tissue. In this way, hormones have an incredible ability to communicate with specific tissues and organs because they are designed to recognize and interact with specific receptors. It's a highly coordinated system that ensures effective communication throughout the body, allowing different parts to work together harmoniously. I hope this fictional story helps you understand how hormones find their way to the right tissues and organs. Our bodies are truly amazing, and the intricate mechanisms within them never cease to amaze me. If you have any more questions, feel free to ask!


Why are Organs not tissues?

Organs are made up of many tissues. Tissues are a building block of organs. For example: Tissues are to organs as bricks are to houses.

No because in order to have organs you must have tissues. Organs are made out of tissues so there for an organism with organs must have tissues as well.
