输送 (shū sòng) is a transitive verb meaning 'to transport', 'to convey', or 'to deliver'—especially over distance or through a system. The first character 输 (shū) means 'to transport' or 'to transmit', often implying movement via infrastructure (e.g., pipelines, blood vessels, or logistics networks); the second character 送 (sòng) means 'to send' or 'to deliver', adding directionality and purpose. Together, they emphasize systematic, often continuous or large-scale movement of people, goods, fluids, or signals.

This word is commonly used in formal, technical, or institutional contexts: medical (e.g., blood circulation), engineering (e.g., water or gas pipelines), logistics (e.g., cargo distribution), and even abstract domains like data transmission. It’s rarely used for casual, one-off hand-deliveries—that’s more appropriately expressed with 送 (sòng) alone. 输送 carries a neutral-to-formal register and frequently appears in compound nouns like 输送带 (conveyor belt) or 输送系统 (transportation system).
