A tubule is a small tube-like structure found in various parts of the body. They're like tiny pipes that transport fluids and other substances. Think of them as the plumbing system of your cells and organs! ๐ง They're essential for processes like filtering waste in the kidneys (renal tubules) and transporting sperm in the testes (seminiferous tubules). Their small size allows for efficient transport and exchange of materials. They come in many sizes and complexities. ๐
