Question

Quizplus · Accepted Answer

The lymphatic system collects fluid that seeps into the tissues, which is then filtered and returned to the bloodstream. While it is connected to the circulatory system, it is not a closed system like the circulatory system. It is mostly uni-directional, moving from the tissues to the bloodstream, but it can also be bi-directional to a limited extent. The lymphatic vessels exhibit rhythmic contractions, but not peristaltic contractions. The lymphatic system also plays a role in immune function, transporting immune cells and removing pathogens and cell debris. It does not carry all metabolites from the small intestine to the liver, as some are transported via the portal vein.
