Which term describes the rate at which lymph is transported through the lymphatic system per unit time?

• A. Lymph time volume
• B. Transport capacity
• C. Filtration
• D. Edema

Answer: (A)

The rate at which lymph is moved through the lymphatic system is determined by how much lymph passes a given point in a specific time. Lymph time volume is the term used to describe that volume moving per unit of time, essentially the transport rate of the lymphatic system. It directly reflects how quickly lymph is being conveyed through the pathways, which is exactly what this question is asking about.

Transport capacity refers to the system’s maximum ability to move lymph, not the actual rate at a moment. Filtration describes fluid leaving capillaries into tissues, not the overall lymph transport rate. Edema is the buildup of excess interstitial fluid, a consequence of imbalance between fluid movement and lymph drainage, not a measure of transport rate.
