Final answer:
The clear fluid collected from body tissues and transported into the venous circulation is known as lymph. It's part of the lymphatic system's function to maintain fluid balance and provide filtration through lymph nodes.
Step-by-step explanation:
A clear fluid collected from body tissues and transported to the venous circulation is D. lymph. The lymphatic system plays a critical role in maintaining fluid balance within the body. It drains excess interstitial fluid, now called lymph, from the tissue spaces and returns it to the bloodstream. Every day, roughly 20 liters of plasma are released into the interstitial space from capillaries, with 17 liters directly reabsorbed and the remaining three liters collected by the lymphatic system.
Lymphatic capillaries absorb this fluid, which then passes through lymph nodes that filter out harmful organisms and cell debris. This function of the lymphatic system is essential for the body's defense mechanisms and the maintenance of homeostasis.
