The vas deferens (also called the ductus deferens) is a muscular tube that carries sperm from the epididymis to the ejaculatory duct. It's a key component of the male reproductive system. During ejaculation, the smooth muscle in the vas deferens contracts, propelling sperm forward. Think of it as the sperm's highway to delivery! 🛣️ It ensures the sperm reach their final destination.
