Large amounts of ground substance are found in A) connective tissue (B) muscle tissue (C) nervous tissue (D) epithelial tissue

If you guessed connective tissue, you're right! Connective tissue is the body’s support system, and it's packed with ground substance, which is a gel-like material that fills the spaces between cells and fibers. This ground substance is crucial as it helps in nutrient exchange and provides a medium for cell communication. Think of it as the glue that holds everything together! Now, let’s dive into the real-world application. Imagine a soft, spongy padding you sit on or a thick gel that cushions your joints—yep, that's connective tissue doing its handy work! It’s not just about structural support; it's pivotal in wound healing, insulations (like in fat tissue), and even in fighting off infections through its role in immune responses. Quite the multitasker, isn't it?
