How does the lymphatic system contribute to maintaining normal blood volume?
Understand the Problem
The question is asking how the lymphatic system helps keep the blood volume at a normal level. It presents four options, and we need to determine which one accurately describes the lymphatic system's role in blood volume regulation.
Answer
The lymphatic system collects excess fluid from tissues and returns it to the bloodstream to maintain blood volume.
The lymphatic system maintains normal blood volume by collecting excess fluid (lymph) from tissues and returning it to the bloodstream. This process prevents fluid buildup in tissues (edema) and helps sustain adequate blood volume and pressure.

More Information
The lymphatic system also plays a crucial role in immune function by transporting immune cells and filtering pathogens from the lymph.
Tips
A common mistake is to think the lymphatic system acts as a closed loop like the blood circulatory system; it is an open system that collects and returns fluid.
