👉 A "with fluid" refers to a substance that flows or moves freely, often in response to external stimuli or pressure changes. In various contexts, it can describe a liquid that behaves similarly to water, such as blood in the circulatory system or synovial fluid in joints, which helps lubricate and cushion tissues. In a broader sense, it can also describe any fluid that exhibits dynamic properties, like blood flow in arteries or the movement of cerebrospinal fluid in the brain. This term highlights the fluid's ability to adapt and change its state or behavior based on the surrounding environment or physiological needs.
